Let's learn how to create an answering machine!
|
||||
|
||||
### ~
|
||||
|
||||
We will use `show string` to show text on the LED screen. *String* is a common name for *text* in programming languages. The function `show string` scrolls the text column by column at a *150* milliseconds interval.
|
||||
|
||||

# answering machine blocks challenges
|
||||
|
||||
Coding challenges for the answering machine tutorial.
|
||||
|
||||
## Before we get started
|
||||
|
||||
Complete the [answering machine](/lessons/answering-machine/activity) activity and your code will look like this:
|
||||
|
||||
```blocks
|
||||
basic.showString("ASK ME A QUESTION")
|
||||
```
|
||||
|
||||
### Challenge 1
|
||||
|
||||
Now we need to reply after someone asks micro:bit a yes or no question. We want to respond `YES` when button `A` is pressed. Add a condition for button `A` and inside it show the string `YES`.
|
||||
|
||||
```blocks
|
||||
basic.showString("ASK ME A QUESTION")
|
||||
input.onButtonPressed(Button.A, () => {
|
||||
basic.showString("Yes")
|
||||
})
|
||||
```
|
||||
|
||||
* `Run` the code to see if it works as expected.
|
||||
|
||||
### Challenge 2
|
||||
|
||||
What if micro:bit's answer to the question is no? Let's have `NO` be displayed when button `B` is pressed. Add a condition for button `B` and inside it show the string `NO`.
|
||||
|
||||
```blocks
|
||||
basic.showString("ASK ME A QUESTION")
|
||||
input.onButtonPressed(Button.A, () => {
|
||||
basic.showString("Yes")
|
||||
})
|
||||
input.onButtonPressed(Button.B, () => {
|
||||
basic.showString("NO")
|
||||
})
|
||||
|
||||
```
|
||||
|
||||
* `Run` the code to see if it works as expected.
|
||||
|
||||
### Challenge 3
|
||||
|
||||
When you are asked a yes or no question, do you always say yes or no? Add a condition for `on shake` that displays `MAYBE`.

# blink blocks activity

Turn an LED on and off with forever
|
||||
|
||||
### ~avatar avatar
|
||||
|
||||
```sim
|
||||
basic.forever(() => {
|
||||
led.plot(2, 2)
|
||||
basic.pause(500)
|
||||
led.unplot(2, 2)
|
||||
basic.pause(500)
|
||||
})
|
||||
```
|
||||
Let's build a blinking light!
|
||||
|
||||
### ~
|
||||
|
||||
Have you ever tried to blink a flashlight at night? The concept is fairly simply: turn on the light, wait for a little, turn off the light, wait again, and repeat. That's exactly what we need to code to get a blinking LED.
|
||||
|
||||
Let's start by adding a line of code that turns on the LED at position 2, 2.
|
||||
|
||||
```blocks
|
||||
led.plot(2, 2)
|
||||
```
|
||||
|
||||
Run your script to make sure it's correct. Then, let's add code to `pause` 500 milliseconds and turn off the LED.
|
||||
|
||||
```blocks
|
||||
led.plot(2, 2)
|
||||
basic.pause(500)
|
||||
led.unplot(2,2)
|
||||
```
|
||||
|
||||
We've got the LED blinking once. Let's add another pause and turn on the LED again.
|
||||
|
||||
```blocks
|
||||
led.plot(2, 2)
|
||||
basic.pause(500)
|
||||
led.unplot(2, 2)
|
||||
basic.pause(500)
|
||||
led.plot(2, 2)
|
||||
```
|
||||
|
||||
The current code works but it only blinks once! We are going to use a `forever` loop and move the code inside it to repeat it forever. We've dropped the second `plot` line since we don't need it in the loop.
|
||||
|
||||
```blocks
|
||||
basic.forever(() => {
|
||||
led.plot(2, 2)
|
||||
basic.pause(500)
|
||||
led.unplot(2, 2)
|
||||
basic.pause(500)
|
||||
})
|
||||
```

|
||||
Coding challenges for the blink tutorial
|
||||
|
||||
## Before we get started
|
||||
|
||||
Complete the [blink](/lessons/blink/activity) activity and your code will look like this:
|
||||
|
||||
```blocks
|
||||
basic.forever(() => {
|
||||
led.plot(2, 2)
|
||||
basic.pause(500)
|
||||
led.unplot(2, 2)
|
||||
basic.pause(500)
|
||||
})
|
||||
```
|
||||
|
||||
### Challenge 1
|
||||
|
||||
Let's display a "smiley face" on the screen! We'll start by plotting the eyes.
|
||||
|
||||
Add `plot(1,1)` and `plot(3,1)` under `plot(2,2)` ; then add `unplot(1,1)`, `unplot(3,1)` and `unplot(2,2)` after `pause`. When you're ready, don't forget to run your code to try it out!
|
||||
|
||||
```blocks
|
||||
basic.forever(() => {
|
||||
led.plot(2, 2)
|
||||
led.plot(1, 1)
|
||||
led.plot(3, 1)
|
||||
basic.pause(500)
|
||||
led.unplot(2, 2)
|
||||
led.unplot(1, 1)
|
||||
led.unplot(3, 1)
|
||||
basic.pause(500)
|
||||
})
|
||||
```

Let's add the code to plot the mouth by using `plot` and `unplot` to the following coordinates: (1,4), (2,4) and (3,4). When you're ready, don't forget to run your code to try it out!
|
||||
|
||||
```blocks
|
||||
basic.forever(() => {
|
||||
led.plot(2, 2)
|
||||
led.plot(1, 1)
|
||||
led.plot(3, 1)
|
||||
led.plot(1, 4)
|
||||
led.plot(2, 4)
|
||||
led.plot(3, 4)
|
||||
basic.pause(500)
|
||||
led.unplot(2, 2)
|
||||
led.unplot(1, 1)
|
||||
led.unplot(3, 1)
|
||||
led.unplot(1, 4)
|
||||
led.unplot(2, 4)
|
||||
led.unplot(3, 4)
|
||||
basic.pause(500)
|
||||
})
|
||||
```
|
||||
|
||||
### Challenge 3
|
||||
|
||||
Let's keep using `plot` to convert the mouth into a smiley face.
|
||||
|
||||
```` bitmatrix
|
||||

|
||||
|
||||
### Challenge 4
|
||||
|
||||
Let's make it blink a bit faster. To do so, we need to reduce the amount of time used in ``pause`` to 100 milliseconds.
|
||||
|
||||
### Challenge 5

# blink blocks quiz answers
|
||||
|
||||
Learn how to create a blinking LED script.
|
||||
|
||||
This is the answer key for the [blink quiz](/lessons/blink/quiz).
|
||||
|
||||
## 1. Describe what `plot` does?
|
||||
|
||||
Answers will vary. In general, plot refers to the code that turns on a specific LED. We specify the LED using x, y coordinates.
|
||||
|
||||
## 2. Draw which LED is ON after running this code
|
||||
|
||||
```blocks
|
||||
led.plot(2, 2)
|
||||
|
||||
```
|
||||
|
||||
|
||||
|
||||
By default, the position of an LED on *Blink Tutorial* is set to the centre of the screen. This code turns on the centre LED
|
||||
|
||||
## 3. Draw which LED is ON after running this code
|
||||
|
||||
```blocks
|
||||
led.plot(0, 0)
|
||||
|
||||
```
|
||||
|
||||
|
||||
|
||||
This code turns on specific LED. Plot turns on the specified LED on the LED screen. We specify the LED using x, y coordinates.
|
||||
|
||||
* ``x`` - the x coordinate or horizontal position (0)
|
||||
* ``y`` - the y coordinate or vertical position (0)
|
||||
|
||||
## 4. Draw which LED is ON after running this code
|
||||
|
||||
```blocks
|
||||
led.plot(4, 4)
|
||||
|
||||
```
|
||||
|
||||
|
||||
|
||||
This code turns on specific LED. Plot turns on the specified LED on the LED screen. We specify the LED using ``x``, ``y`` coordinates.
|
||||
|
||||
* ``x`` - the x coordinate or horizontal position (4)
|
||||
* ``y`` - the y coordinate or vertical position (4)

# blocks - if statements
|
||||
|
||||
An introduction to conditions for the Block Editor.
|
||||
|
||||
## Introduction to conditions
|
||||
|
||||
In the introduction to code, we made the BBC micro:bit automatically shows the message ‘hello, world!’:
|
||||
|
||||
|
||||
|
||||
This statement, or code, will happen as soon as the BBC micro:bit is activated. This means it is unconditional. We can add a condition to make code function in certain ways:
|
||||
|
||||
* A calculator waits for the user in input numbers and a function, before outputting a result
|
||||
* A game waits for the user to press a button at the right time before outputting their score
|
||||
* A quiz waits for the user to choose the correct option, and if they are wrong the quiz will tell the user
|
||||
|
||||
In programming we use an ‘if’ statement: if this condition is met, do something. Lets add an if statement to the code we had before; the BBC Micro:bit will wait for the user to press a button before showing the image.
|
||||
|
||||
### Write the code
|
||||
|
||||
Click the **if** category and drag an `if/do` block. Drag the`show string` block we wrote previously into the `do` section of the block. Next click the **input** tab and drag a `button pressed` block, connect it to the open jigsaw of the `if` block. This is our criteria: `if A button is pressed`. We can change which button (button A or B) by clicking the arrow next to ‘A’ and changing the value. This means our BBC micro:bit is waiting for button A (the left button) to be pressed. Finally go to the **basic** tab and drag a `forever` block, and attach all our code inside. We add this block to ensure the BBC micro:bit is always waiting to show us this message, not just once. Your code should look like this:
|
||||
|
||||
|
||||
|
||||
Again, test the code in the simulator. Try clicking **Button A** to display the "hello, world!" message every time the `button is pressed`.
|
||||
|
||||
### More 'if' statements
|
||||
|
||||
You could now add additional conditions to your 'if statement'. Here are some ideas:
|
||||
|
||||
* Change the 'get button' to ask for button B
|
||||
* Add another 'if' statement within the current one, and make it so both buttons must be pressed to show the message
|
||||
* Create a mini quiz that asks for one button to be pressed which represents an answer
|
||||
|
||||
## Else
|
||||
|
||||
What if the user does not press a button? What if the user presses the wrong button? We call this an else, because if the criteria of the if statement are not met then something else is done.
|
||||
|
||||
For example, we could make it so our BBC Micro:bit tells us to press the A button. Remove the `button pressed` and `show string` blocks from the `if` block and right click it and select **Delete**. Now click the **If** category and drag out an `else if` block. Plug the `button pressed` and `show string` blocks in the correct places.
|
||||
|
||||
We want the message "Press A!" to scroll across the BBC micro:bit, so right-click the `show string` block and select **Duplicate**. Drag this new block into the `else` section and replace the “hello, world!” with "Press A!". Your code should look like this:
|
||||
|
||||
|
||||
|
||||
So, to recap: the `forever` block makes sure our code runs forever. The BBC micro:bit checks if the user is pressing the left button, if the user is not then the “Press the button!” message will scroll across the LEDs. If the user is pressing the button then the “hello, world!” message will scroll across the screen. Check this in the simulator or attach the BBC micro:bit to the computer then click **compile** to send the code onto the BBC micro:bit.
|
||||
|
||||
## What is a condition?
|
||||
|
||||
A condition is criteria that the user must meet for a certain function to be carried out.

# bop it challenges
|
||||
|
||||
a game similar to "Simon Says" with the BBC micro:bit.
|
||||
|
||||
## Before we get started
|
||||
|
||||
Complete the following guided tutorial. Your code should look like this:
|
||||
|
||||
```blocks
|
||||
newAction() // ***
|
||||
input.onButtonPressed(Button.A, () => {
|
||||
if (action == 0) {
|
||||
game.addScore(1) // ***
|
||||
newAction() // ***
|
||||
}
|
||||
}) // ***
|
||||
input.onLogoDown(() => {
|
||||
if (action == 1) {
|
||||
game.addScore(1) // ***
|
||||
newAction()
|
||||
}
|
||||
})
|
||||
input.onGesture(Gesture.Shake, () => {
|
||||
if (action == 2) {
|
||||
game.addScore(1)
|
||||
newAction()
|
||||
}
|
||||
})
|
||||
input.onButtonPressed(Button.B, () => {
|
||||
basic.showNumber(game.score(), 150) // ***
|
||||
basic.pause(2000) // ***
|
||||
newAction() // ***
|
||||
})
|
||||
```
|
||||
|
||||
### Challenge 1
|
||||
|
||||
Now let's add some more types of instructions for the player to follow. Let's add `PRESS PIN 0`. Change the global variable `action` to `math->random(4)` so that we can add a new **IF** statement that checks if `action=3`. If it does, display instructions to press pin 0.
|
||||
|
||||
```blocks
|
||||
/**
|
||||
* {highlight}
|
||||
*/
|
||||
export function newAction_() {
|
||||
action = Math.random(4) // ***
|
||||
if (action == 0) {
|
||||
basic.showString("PUSH A", 150) // ***
|
||||
}
|
||||
if (action == 1) {
|
||||
basic.showString("LOGO DOWN", 150) // ***
|
||||
}
|
||||
if (action == 2) {
|
||||
basic.showString("SHAKE", 150) // ***
|
||||
}
|
||||
if (action == 3) {
|
||||
basic.showString("PRESS PIN 0", 150) // ***
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Challenge 2
|
||||
|
||||
Now let's implement `PRESS PIN 0` in the main. Create a condition of `input->on pin pressed("P0")` that will add one to the score and calls the method `new action`.
|
||||
|
||||
```
|
||||
// **. . .**
|
||||
input.onButtonPressed(Button.B, () => {
|
||||
basic.showNumber(game.score(), 150) // ***
|
||||
basic.pause(2000) // ***
|
||||
newAction() // ***
|
||||
}) // ***
|
||||
input.onPinPressed(TouchPin.P0, () => {
|
||||
if (action == 3) {
|
||||
game.addScore(1) // ***
|
||||
newAction() // ***
|
||||
}
|
||||
}) // ***
|
||||
```
|
||||
|
||||

# catch the egg game challenges
|
||||
|
||||
## Before we get started
|
||||
|
||||
Your starting code should look like this:
|
||||
|
||||
```blocks
|
||||
let basketX = 2
|
||||
let eggX = 2
|
||||
let eggY = 0
|
||||
basic.forever(() => {
|
||||
led.unplot(basketX, 4)
|
||||
led.unplot(eggX, eggY)
|
||||
eggY = eggY + 1
|
||||
led.plot(eggX, eggY)
|
||||
basic.pause(300)
|
||||
let accX = input.acceleration(Dimension.X)
|
||||
basketX = 2 + Math.min(2, Math.max(-2, accX / 200))
|
||||
led.plot(basketX, 4)
|
||||
if (eggY > 4) {
|
||||
eggY = -1
|
||||
eggX = Math.random(5)
|
||||
}
|
||||
basic.pause(300)
|
||||
})
|
||||
```
|
||||
|
||||

||||
|
||||
### Challenge 1
|
||||
|
||||
Let's use an **IF** statement to detect if the egg and the basket are lined up.
|
||||
|
||||
Now that we know when an egg is caught, we can keep track of the score! We need to use the `add score` function built into the game library to add `1` point for every egg that is caught. However, let's not forget to `remove life` if an egg falls off the display before it's caught!

### Challenge 2
|
||||
|
||||
Catching eggs gets easier with practice so let's make the eggs fall faster every 5 catches. We can do this by tracking how long the egg pauses in each position while falling with a global variable called **falling pause**. Let's create this variable and set it to `300` initially. Don't forget to also create a condition that will be true every 5 catches.

||||

|
||||
|
||||
### Challenge 3
|
||||
|
||||
Let's make the egg fall faster by decreasing the amount of time it pauses in each position by decreasing **falling pause** by `25` every 5 catches. Now, instead of pausing for 300 milliseconds we can pause for the value of **falling pause**.
|
||||
|
||||
```blocks
|
||||
let basketX3 = 2
|
||||
let eggX3 = 2
|
||||
let eggY3 = 0
|
||||
let fallingPause1 = 300
|
||||
basic.forever(() => {
|
||||
led.unplot(basketX3, 4)
|
||||
led.unplot(eggX3, eggY3)
|
||||
eggY3 = eggY3 + 1
|
||||
led.plot(eggX3, eggY3)
|
||||
basic.pause(300)
|
||||
let accX3 = input.acceleration(Dimension.X)
|
||||
basketX3 = 2 + Math.min(2, Math.max(-2, accX3 / 200))
|
||||
led.plot(basketX3, 4)
|
||||
if (eggY3 > 4) {
|
||||
eggY3 = -1
|
||||
eggX3 = Math.random(5)
|
||||
}
|
||||
if (eggY3 == 4) {
|
||||
if (basketX3 == eggX3) {
|
||||
game.addScore(1)
|
||||
if (game.score()% 5 == 0) {
|
||||
fallingPause1 = fallingPause1 - 25 // ***
|
||||
}
|
||||
} else {
|
||||
game.removeLife(1)
|
||||
}
|
||||
}
|
||||
basic.pause(fallingPause1)
|
||||
})
|
||||
|
||||
```
|
||||
|
||||
Fantastic! Your game is now ready to show off.

# blocks - challenges
|
||||
|
||||
Extra stuff for the Block Editor - an introduction to GPIO
|
||||
|
||||
## Before we get started
|
||||
|
||||
This section details challenges for the BBC micro:bit. Ensure you have completed all other sections of the Microsoft Block Editor tutorials before attempting these challenges!
|
||||
|
||||
## Quiz Challenge [1]
|
||||
|
||||
Using if statements, try to add more statements to create a simple quiz. The user will be told if the question is right or not, and will have two options (button A and button B).
|
||||
|
||||
Here is some sample code for a simple quiz:
|
||||
|
||||
|
||||
|
||||
## Timer Challenge [2]
|
||||
|
||||
Create a timer that runs out after a certain amount of time (using the *count* loop). For an extra challenge, let the user input the amount of seconds they want the timer to run for using variables and the buttons as input. The solution is below.
|
||||
|
||||
|
||||
|
||||
## Graphics Challenges [3]
|
||||
|
||||
Using the knowledge you have learnt from the [rendering graphics](/lessons/graphics) section, try creating an algorithm to draw these shapes. Before you write the code try to figure out how the BBC micro:bit will be thinking to plot these points. For example, with our diagonal line – “count up from 0 to 4 by 1, and plot points x=i and y=i”.
|
||||
|
||||
* Another diagonal line
|
||||
* A square going around the board
|
||||
* A filled square
|
||||
* A square which unplots itself after
|
||||
* A filled square which then unplots itself
|
||||
|
||||
The solutions are below.
|
||||
|
||||
### Square [3.1]
|
||||
|
||||
|
||||
|
||||
### Filled square [3.2]
|
||||
|
||||
|
||||
|
||||
### Vanishing square [3.3]
|
||||
|
||||
Use the same code and algorithm for the square solution, only use the ‘unplot’ block to make this LED turn off again. You could also reverse the algorithm.
|
||||
|
||||
### Vanishing filled square [3.4]
|
||||
|
||||
Use the same code and algorithm for the filled square solution, only use the `unplot` block to make this LED turn off again. You could also reverse the algorithm.
|
||||
|
||||
## Animation Challenge [4]
|
||||
|
||||
Use your new knowledge of animations and algorithms to program your BBC micro:bit to act human: for example, you could make your BBC micro:bit smile and wink. Remember you can display images with the `show image` and `create image` blocks. Sample code is below.
|
||||
|
||||
|
||||
|
||||
## Electronic Dice Challenge [5]
|
||||
|
||||
Using the code in the Random Numbers tutorial in Section 6, or your own algorithm, create an electronic dice that displays the values appropriate for a dice (so 1 shows a single LED on in the center, two shows two LEDs on at each corner, etc.). You may want to declare image variables to do this, then check what it is equal to using an ‘if’ statement. Sample code is below.
|
||||
|
||||
|
||||
|
||||
## Calculator Challenge [6]
|
||||
|
||||
Using your knowledge of loops, counters and math, create a calculator.
|
||||
|
||||
The calculator should:
|
||||
|
||||
* Count the amount of times the user presses the left button before pressing the right button (this is the first value, or valueOne)
|
||||
* Count the amount of times the user presses the left button before the right button again (this is the second value, or valueTwo)
|
||||
* Scroll through operations (+,-, x and divide) until the user presses the right button to make a choice
|
||||
* Perform the calculation
|
||||
* Show the entire calculation, for example: 5 + 10 = 15
|
||||
|
||||
Sample code is below.
|
||||
|
||||
|
||||
|
||||
## Smart watch Challenge [8]
|
||||
|
||||
Create a smart watch using the BBC micro:bit. Create a menu where the user presses one button to cycle through options and another button to choose this option. Add applications to this smart watch:
|
||||
|
||||
* Calculators
|
||||
* Games
|
||||
* Random number generators
|
||||
|
||||
And any other applications you can think of.

# Activity
|
||||
|
||||
Measure the acceleration on the micro:bit in the "x" direction.
|
||||
|
||||
### ~avatar avatar
|
||||
|
||||
Welcome! This activity will teach how to use the micro:bit to chart the acceleration in the "x" direction. Let's get started!
|
||||
|
||||
|
||||
### ~
|
||||
Let's measure `acceleration (mg)` in the "x" direction. Get the acceleration value (milli g-force), in one of three specified dimensions.
|
||||
|
||||
|
||||
```blocks
|
||||
input.acceleration(Dimension.X)
|
||||
```
|
||||
|
||||
### ~
|
||||
Use the plot bar chart to visualize the acceleration on the LED screen of the micro:bit in the specified range. You implement plot Bar Graph to display a vertical bar graph based on the "value" and "high" value. Then you must insert acceleration in the X dimension to measure the acceleration.
|
||||
|
||||
```blocks
|
||||
basic.forever(() => {
|
||||
led.plotBarGraph(input.acceleration(Dimension.X), 0)
|
||||
})
|
||||
|
||||
```
|
||||
|
||||
### ~
|
||||
Notice that moving the micro:bit in the simulator from left to right (x direction) changes the values beneath the micro:bit in a range from 1023 to -1023 as measured in milli-gravities. By hovering over the micro:bit from left to right, you can observe changing values beneath the micro:bit simulator. Also, the LEDs shown on the Bar Graph fluctates based on the movement of the micro:bit simulator in the x direction. The line underneath the micro:bit simulator reflect the acceleration in the x direction.
|
||||
|
||||
NOTE: The colors of the charts reflect the color of the micro:bit simulator. In this instance, the micro:bit is yellow. So the color of the data line reflects the color of the micro:bit
|
||||
|
||||
|
||||
|
||||
### ~
|
||||
|
||||
Vigorously move the micro:bit in the micro:bit simulatator by moving the micro:bit image from side to side. Every time the micro:bit moves in the x direction in the simulator, you are generating data points that can be reviewed in Excel. The more attempts to move the micro:bit from side to side, the more data being saved in Excel. After you have vigarously moved the micro:bit simulator from side to side for a sufficient amount of time, you are ready to graph or chart the accceleration of the micro:bit. We want a printout of our acceleration on Excel that can be graphed in Excel.
|
||||
|
||||
### ~
|
||||
|
||||
We want to chart the data collected by using a tool in Excel.
|
||||
|
||||
The final part of this experiment is opening and reviewing the data in the Excel CSV file. Simply click on the line beneath the simulator. A CSV file will be generated to display the data points collected by moving the micro:bit in the X direction. Then click or tap on the data Excel file that was downloaded to your local ``Downloads`` Folder.
|
||||
|
||||
|
||||
### ~
|
||||
|
||||
|
||||
First, click or tap on the first two columns (A, B) to include the time of the data being collected; b) the results of acceleration data on the micro:bit
|
||||
|
||||
|
||||
|
||||
Use the Recommended Charts command on the Insert tab to quickly create a chart that’s just right for your data.
|
||||
|
||||
* Select the data that you want to include in your chart.
|
||||
|
||||
* Click Insert > Recommended Charts.
|
||||
|
||||
|
||||
|
||||
* On the Recommended Charts tab, scroll through the list of chart types that Excel recommends for your data. Pick the **scatter plot**.

# Challenge
|
||||
|
||||
### ~avatar avatar
|
||||
|
||||
Welcome! The activity will teach you how to use the acceleration of the 1st micro:bit and to visualize the acceleration on the 2nd micro:bit.
|
||||
Let's get started!
|
||||
|
||||
### ~
|
||||
Let's measure `acceleration (mg)` and then `send number`. `Acceleration` is measured in **milli-gravities**, so a value of -1000 is equivalent to -1g or -9.81m/s^2. We will be able to get the acceleration value (g-force), in the specified "x" dimension. `Send number` will broadcast a number data packet to other micro:bits connected via radio.
|
||||
|
||||
```blocks
|
||||
radio.sendNumber(input.acceleration(Dimension.X));
|
||||
```
|
||||
### ~
|
||||
We want to display the acceleration forever. In order to do so, we need a `forever` loop. A forever loop will repeat code in the background forever.
|
||||
|
||||
```blocks
|
||||
basic.forever(() => {
|
||||
radio.sendNumber(input.acceleration(Dimension.X));
|
||||
});
|
||||
|
||||
|
||||
```
|
||||
### ~
|
||||
We want to register code to run when a packet is received over radio. We can implement this code by adding `on data received`.
|
||||
|
||||
```blocks
|
||||
basic.forever(() => {
|
||||
radio.sendNumber(input.acceleration(Dimension.X))
|
||||
})
|
||||
radio.onDataReceived(() => {
|
||||
|
||||
})
|
||||
```
|
||||
### ~
|
||||
Finally, we want to chart the acceleration. So we must first implement `plot bar graph`. `Plot Bar Graph` will display a vertical bar graph based on the value and high value. In order to transfer the receive the number from the 1st micro:bit, we must implement `receive number` to constantly display a vertical bar graph based on the value. Remember, the value will equal to the micro:bit's acceleration in the "x" direction.
|
||||
|
||||
```blocks
|
||||
basic.forever(() => {
|
||||
radio.sendNumber(input.acceleration(Dimension.X))
|
||||
})
|
||||
radio.onDataReceived(() => {
|
||||
led.plotBarGraph(radio.receiveNumber(), 1023)
|
||||
})
|
||||
|
||||
```
|
||||
### ~
|
||||
Notice that moving the micro:bit the farthest direction in the x direction will be -1023 on the charting beneath the simulator. The second observation will be that the LEDs will be full brightness on the 2nd micro:bit. There is a single LED turned on with the 1st micro:bit. Additionally, the graphs will reflect 0 acceleation for the 1st micro:bit. In this scenario, if you are adjusting the acceleration in the simualator, you are also changing your chart that will be produced.
|
||||
|
||||
|
||||
|
||||
### ~
|
||||
NOTE: The colors of the charts reflect the color of the micro:bit simulator. In this instance, the micro:bits are blue and green. So the colors of the line graphs reflect the colors of the micro:bit
|
||||
|
||||
### ~
|
||||
After running this simulation several seconds by moving the micro:bit side to side in the x direction, you are ready to graph or chart the accceleration of the micro:bit. We want a printout of our acceleration on Excel. We will graph the fluctuating acceleration of the simulation experiment.
|
||||
|
||||
|
||||
|
||||
### ~
|
||||
Finally, you must open the Excel CSV file by clicking on the data.xls file that was downloaded to Downloads Folder.
|
||||
|
||||
|
||||
|
||||
Use the Recommended Charts command on the Insert tab to quickly create a chart that’s just right for your data.
|
||||
|
||||
* Select the data that you want to include in your chart.
|
||||
|
||||
* Click Insert > Recommended Charts.
|
||||
|
||||
|
||||
|
||||
* On the Recommended Charts tab, scroll through the list of chart types that Excel recommends for your data. Pick the **scatter plot**.
|
||||
|
||||
|
||||
|
||||
* Use the Chart Elements, Chart Styles, and Chart Filters buttons next to the upper-right corner of the chart to add chart elements like axis titles or data labels, to customize the look of your chart
|
||||
|
||||
|
||||
|
||||
### ~
|
||||
Have fun reviewing your simulation and analyze the acceleration by chart the Excel data using Excel.
|
||||
|
||||

# beatbox activity
|
||||
|
||||
Control images with variables.
|
||||
|
||||
Have you ever tried to making beat box sounds? Let's try making a beatbox with code!
|
||||
|
||||
Let's start by adding a variable where you can store data. Then rename the variable to "sound". Then set the value of the variable to the note block `A` from the Music drawer. Modify your code so that your code looks like this.
|
||||
|
||||
```blocks
|
||||
let sound = music.noteFrequency(Note.A);
|
||||
```
|
||||
|
||||
We want to play music on pin pressed in order to register an event handler that will execute whenever when you run a script and click pin 1 on the simulator. We must start by opening the Input drawer and adding `on pin pressed` P1. Modify your code so that your code looks like this.
|
||||
|
||||
```blocks
|
||||
let sound = music.noteFrequency(Note.A);
|
||||
input.onPinPressed(TouchPin.P1, () => {
|
||||
|
||||
})
|
||||
```
|
||||
|
||||
We want to code the notes that will be played `on pin pressed`. We click on the Input drawer then insert a `for loop` that will increment by *i*. Click on the Variables drawer. Add `set item` block. Rename the variable block to "sound." Then add a Maths block to increase the variable sound from the note frequency of block `A` to `A` plus 25.Modify your code so that your code looks like this
|
||||
|
||||
```blocks
|
||||
let sound = music.noteFrequency(Note.A);
|
||||
input.onPinPressed(TouchPin.P1, () => {
|
||||
for (let i = 0; i < 4; i++) {
|
||||
sound = sound + 25
|
||||
}
|
||||
})
|
||||
```
|
||||
|
||||
Include a play block with the variable called "sound" and insert a music note block `1/16`. Modify your code so that your code looks like this
|
||||
|
||||
```blocks
|
||||
let sound = music.noteFrequency(Note.A);
|
||||
input.onPinPressed(TouchPin.P1, () => {
|
||||
for (let i = 0; i < 5; i++) {
|
||||
sound = sound + 25
|
||||
music.playTone(music.noteFrequency(sound), music.beat(BeatFraction.Sixteenth));
|
||||
}
|
||||
|
||||
})
|
||||
|
||||
```
|
||||
|
||||
|
||||
* click *run* to see if the code works as expected.

# beatbox challenges
|
||||
|
||||
Create sounds with variables.
|
||||
|
||||
## Before we get started
|
||||
|
||||
Complete the [beatbox](/lessons/classic-beatbox/activity) activity and your code will look like this:
|
||||
|
||||
|
||||
```blocks
|
||||
let sound = music.noteFrequency(Note.A);
|
||||
input.onPinPressed(TouchPin.P1, () => {
|
||||
for (let i = 0; i < 4; i++) {
|
||||
sound = sound + 25
|
||||
music.playTone(music.noteFrequency(sound), music.beat(BeatFraction.Sixteenth));
|
||||
}
|
||||
})
|
||||
```
|
||||
|
||||
### Challenge 1
|
||||
|
||||
Let's include a second sound `on pin pressed` *P2*. To do this, you need to add the same blocks as the banana keyboard activity. However, you must change alter `on pin pressed` from P1 to P2. Additionally, you must *decrease* the frequency of the variable "sound" by 25. Modify your code so that your code looks like this
|
||||
|
||||
|
||||
```blocks
|
||||
let sound = music.noteFrequency(Note.A);
|
||||
input.onPinPressed(TouchPin.P1, () => {
|
||||
for (let i = 0; i < 5; i++) {
|
||||
sound = sound + 25
|
||||
music.playTone(music.noteFrequency(sound), music.beat(BeatFraction.Sixteenth));
|
||||
}
|
||||
|
||||
})
|
||||
input.onPinPressed(TouchPin.P2, () => {
|
||||
for (let i = 0; i < 5; i++) {
|
||||
sound = sound - 25
|
||||
music.playTone(music.noteFrequency(sound), music.beat(BeatFraction.Sixteenth));
|
||||
}
|
||||
|
||||
})
|
||||
```
|
||||
|
||||
* click *run* to see if the code works as expected.
|
||||
|
||||
### Challenge 2
|
||||
|
||||
Finally, we want images to be displayed with sounds `on pin pressed`. Add `show LEDs` blocks under `on pin pressed` P1 and P2.

### ~avatar avatar
|
||||
|

Welcome! This guided tutorial will show you how to program a script that displays the direction the micro:bit is pointing. Let's get started!
|
||||
|
||||
### ~
|
||||
|
||||
Create a loop that will continuously update the reading of the compass.
|
||||
|
||||
|
||||
```blocks
|
||||
basic.forever(() => {
|
||||
|
||||
})
|
||||
```
|
||||
|
||||
Store the reading of the micro:bit in a variable called `degrees`.
|
||||
|
||||
```blocks
|
||||
basic.forever(() => {
|
||||
let degrees = input.compassHeading()
|
||||
})
|
||||
```
|
||||
|
||||
If `degrees` is less than `45`, then the compass heading is mostly pointing toward North. Display `N` on the micro:bit.
|
||||
|
||||
```blocks
|
||||
basic.forever(() => {
|
||||
let degrees = input.compassHeading();
|
||||
if (degrees < 45) {
|
||||
basic.showString("N");
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
If `degrees` is less than 135, the micro:bit is mostly pointing East. Display `E` on the micro:bit.
|
||||
|
||||
|
||||
```blocks
|
||||
basic.forever(() => {
|
||||
let degrees = input.compassHeading();
|
||||
if (degrees < 45) {
|
||||
basic.showString("N");
|
||||
}
|
||||
else if (degrees < 135) {
|
||||
basic.showString("E");
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
If `degrees` is less than 225, the micro:bit is mostly pointing South. Display `S` on the micro:bit.
|
||||
|
||||
|
||||
```blocks
|
||||
basic.forever(() => {
|
||||
let degrees = input.compassHeading();
|
||||
if (degrees < 45) {
|
||||
basic.showString("N");
|
||||
}
|
||||
else if (degrees < 135) {
|
||||
basic.showString("E");
|
||||
}
|
||||
else if (degrees < 225) {
|
||||
basic.showString("S");
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
|
||||
If none of these conditions returned true, then the micro:bit must be pointing West. Display `W` on the micro:bit.
|
||||
|
||||
```blocks
|
||||
basic.forever(() => {
|
||||
let degrees = input.compassHeading();
|
||||
if (degrees < 45) {
|
||||
basic.showString("N");
|
||||
}
|
||||
else if (degrees < 135) {
|
||||
basic.showString("E");
|
||||
}

|
||||
Display a number with a variable.
|
||||

|
||||
Welcome! This tutorial will teach you how to make a counter that increments when button A is pressed. Let's get started!
|
||||
|
||||
### ~
|
||||
|
||||
Let's start by creating a **local variable** `count` to keep track of the current count.
|
||||
|
||||
```blocks
|
||||
let count = 0
|
||||
```
|
||||
|
||||
The code under ``on button pressed("A")`` will run each time the user presses A. Let's add a line of code that increments `count` by `1`.
|
||||
|
||||
```blocks
|
||||
let count = 0
|
||||
input.onButtonPressed(Button.A, () => {
|
||||
count = count + 1
|
||||
})
|
||||
```
|
||||
|
||||
Since the count has changed, it's time to refresh the screen display. Let's add a line of code to display the count on screen.
|
||||
|
||||
|
||||
```blocks
|
||||
let count = 0
|
||||
input.onButtonPressed(Button.A, () => {
|
||||
count = count + 1
|
||||
basic.showNumber(count)
|
||||
})
|
||||
```

# counter challenges
|
||||
|
||||
Coding challenges for the counter.
|
||||
|
||||
## Before we get started
|
||||
|
||||
Complete the following [guided tutorial](/lessons/counter/activity) At the end of the tutorial, click **keep editing**. Your code should look like this:
|
||||
|
||||
```blocks
|
||||
let count = 0
|
||||
input.onButtonPressed(Button.A, () => {
|
||||
count = count + 1
|
||||
basic.showNumber(count)
|
||||
})
|
||||
```
|
||||
|
||||
### Challenge 1
|
||||
|
||||
Let's add the code to `count` when `B` is pressed. Add an event handler with `on button pressed(B)` then add the code to `count`.
|
||||
|
||||
|
||||
```blocks
|
||||
let count = 0
|
||||
input.onButtonPressed(Button.A, () => {
|
||||
count = count + 1
|
||||
basic.showNumber(count)
|
||||
})
|
||||
input.onButtonPressed(Button.B, () => {
|
||||
count = count - 1
|
||||
basic.showNumber(count)
|
||||
})
|
||||
```
|
||||
|
||||
### Challenge 3
|
||||
|
||||
Now let's try to reset the counter when the micro:bit is shaken. You will need to register an event handler with `on shake`.

# counter quiz answers
|
||||
|
||||
Learn how to create a counter with the BBC micro:bit button.
|
||||
|
||||
This is the answer key for the [counter quiz](/lessons/counter/quiz).
|
||||
|
||||
## 1. What is a variable?
|
||||
|
||||
Answers may vary but a variable is a place where you can store and retrieve data
|
||||
|
||||
## 2. Draw the stored value for the variable called count
|
||||
|
||||
```blocks
|
||||
let count = 0
|
||||
```
|
||||
|
||||
|
||||
|
||||
We create a **variable**, `count` to keep track of the current count. The number 0 is stored into memory of the variable.
|
||||
|
||||
<br/>
|
||||
|
||||
## 3. Draw which LEDs are ON after running this code and pressing button "A" once. Explain you chose to draw that number
|
||||
|
||||
```blocks
|
||||
let count = 0
|
||||
input.onButtonPressed(Button.A, () => {
|
||||
count = count + 1
|
||||
basic.showNumber(count)
|
||||
})
|
||||
```
|
||||
|
||||
|
||||
|
||||
We are only pressing on button pressed once. So the number to display on the micro:bit is also one.
|
||||
|
||||
<br/>
|
||||
|
||||
## 4. Draw which LEDs are ON after running this code and pressing button "A" three times. Explain you chose to draw that number
|
||||
|
||||
```blocks
|
||||
let count = 0
|
||||
input.onButtonPressed(Button.A, () => {
|
||||
count = + 1
|
||||
basic.showNumber(count)
|
||||
})
|
||||
```
|
||||
|
||||
|
||||
|
||||
We included the code ``on button pressed("A")`` that runs each time the user presses A. The code increments `count` by `1`. We increase `count` by 1 whenever the user presses the button. So the third time the A button is pressed on the BBC micro:bit, the number 3 is displayed

# dice roll activity
|
||||
|
||||
Create a dice on the micro:bit
|
||||
|
||||
### ~avatar avatar
|
||||
|
||||
Welcome! This tutorial will help you create a dice. Let's get started!
|
||||
|
||||
### ~
|
||||
|
||||
Let's create a condition for when the micro:bit is shaken.
|
||||
|
||||
|
||||
```blocks
|
||||
input.onGesture(Gesture.Shake, () => {
|
||||
|
||||
})
|
||||
```
|
||||
|
||||
We need to show a random value from 1 to 6 on our dice. So let's make a local variable called **roll**.
|
||||
|
||||
```blocks
|
||||
input.onGesture(Gesture.Shake, () => {
|
||||
let roll = Math.random(6)
|
||||
})
|
||||
```
|
||||
|
||||
We need a condition for if **roll** is 5. We will show a `6` if **roll** is 5 because **roll** has a range from 0 to 5. We can use `show LEDs` to display the side of a dice that shows 6.
|
||||
|
||||
|
||||
```blocks
|
||||
input.onGesture(Gesture.Shake, () => {
|
||||
let roll = Math.random(6);
|
||||
if (roll == 5) {
|
||||
basic.showLeds(`
|
||||
. # . # .
|
||||
. . . . .
|
||||
. # . # .
|
||||
. . . . .
|
||||
. # . # .`);
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
|
||||
Let's use an `else if` condition for if **roll** is 4. If **roll** is 4 we can show 5 dots on the dice.
|
||||
|
||||
|
||||
```blocks
|
||||
input.onGesture(Gesture.Shake, ()=> {
|
||||
let roll = Math.random(6);
|
||||
if (roll == 5) {
|
||||
basic.showLeds(`
|
||||
. # . # .
|
||||
. . . . .
|
||||
. # . # .
|
||||
. . . . .
|
||||
. # . # .`);
|
||||
}
|
||||
else if (roll == 4) {
|
||||
basic.showLeds(`
|
||||
. . . . .
|
||||
. # . # .
|
||||
. . # . .
|
||||
. # . # .
|
||||
. . . . .`);
|
||||
}
|
||||
});
|
||||
|
||||
```
|
||||
|
||||
|
||||
Now we need to repeat the same steps for if **roll** is 3. If **roll** is 3 we will show `4` on the dice.
|
||||
|
||||
|
||||
```blocks
|
||||
input.onGesture(Gesture.Shake, () => {
|
||||
let roll = Math.random(6);
|
||||
if (roll == 5) {
|
||||
basic.showLeds(`
|
||||
. # . # .
|
||||
. . . . .
|
||||
. # . # .
|
||||
. . . . .
|
||||
. # . # .`);
|
||||
}
|
||||
else if (roll == 4) {
|
||||
basic.showLeds(`
|
||||
. . . . .
|
||||
. # . # .
|
||||
. . # . .
|
||||
. # . # .
|
||||
. . . . .`);
|
||||
}
|
||||
else if (roll == 3) {
|
||||
basic.showLeds(`
|
||||
. . . . .
|
||||
. # . # .
|
||||
. . . . .
|
||||
. # . # .
|
||||
. . . . .`);
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
|
||||
Let's also repeat these steps to show the 3, 2, and 1 on the dice. We are almost done with our dice!
|
||||
|
||||
```blocks
|
||||
input.onGesture(Gesture.Shake, () => {
|
||||
let roll = Math.random(6);
|
||||
if (roll == 5) {
|
||||
basic.showLeds(`
|

. # . # .
|
||||
. . . . .
|
||||
. # . # .
|
||||
. . . . .
|

. # . # .`);
|
||||
}
|
||||
else if (roll == 4) {
|
||||
basic.showLeds(`
|
||||
. . . . .
|
||||
. # . # .
|
||||
. . # . .

. . . . .`);
|
||||
}
|
||||
else if (roll == 3) {
|
||||
basic.showLeds(`
|

. . . . .
|
||||
. # . # .
|

|
||||
}
|
||||
else if (roll == 2) {
|
||||
basic.showLeds(`
|
||||
# . . . .
|
||||
. . . . .
|
||||
. . # . .
|
||||
. . . . .
|
||||
. . . . #`);
|
||||
}
|
||||
else if (roll == 1) {
|
||||
basic.showLeds(`
|

. . . . .
|
||||
. # . . .
|

# dice roll challenges
|

Create a dice on the micro:bit.
|
||||
|

## Before we get started
|

```
|

### Challenge 1
|
||||
|
||||
Modify the line of code with `pick random` so that only number 1-4 can appear on the dice.
|
||||
|

### Challenge 2
|
||||
|
||||
Let's make a trick dice! Modify the line of code with `pick random` so that only numbers 3-6 can appear on the dice. Also note that we need to ensure `roll = 0` when only 1 dot is shown on the BBC micro:bit.
|
||||
|
||||
```blocks
|
||||
input.onGesture(Gesture.Shake, () => {
|
||||
let roll = Math.random(4) + 2;
|
||||
if (roll == 5) {
|
||||
basic.showLeds(`
|
||||
. # . # .
|
||||
. . . . .
|
||||
. # . # .
|

. # . # .`);
|
||||
}
|
||||
else if (roll == 4) {
|

basic.showLeds(`
|
||||
. . . . .
|

. . # . .
|

else if (roll == 3) {
|
||||
basic.showLeds(`
|
||||
. . . . .
|
||||
. # . # .
|
||||
. . . . .
|

. . . . .`);
|

|
||||
Create a counter with a while loop.
|
||||
|
||||
### ~avatar avatar
|
||||
|
||||
Welcome! This tutorial will teach how to create a counter with a while loop. Let's get started!
|
||||
|
||||
### ~
|
||||
|
||||
Create a variable that acts as a counter and set it to 0.
|
||||
|
||||
```blocks
|
||||
let count = 0
|
||||
```
|
||||
|
||||
Add a while loop that will loop over and over until the variable `count` equals 10.
|
||||
|
||||
|
||||
```blocks
|
||||
let count = 0
|
||||
while (count < 10) {
|
||||
|
||||
}
|
||||
|
||||
```
|
||||
|
||||
Let's add a pause. Then show the value of the the count.
|
||||
|
||||
|
||||
```blocks
|
||||
let count = 0;
|
||||
while (count < 10) {
|
||||
basic.pause(100);
|
||||
basic.showNumber(count)
|
||||
}
|
||||
|
||||
```
|
||||
|
||||
Increase the value of count by one.
|
||||
|
||||
|
||||
```blocks
|
||||
let count = 0
|
||||
while (count < 10) {
|
||||
basic.pause(100)
|
||||
basic.showNumber(count)
|
||||
count = count + (count - 1)
|
||||
}
|
||||
```

# digi yoyo challenges
|
||||
|
||||
Coding challenges for the digi yoyo.
|
||||
|
||||
## Before we get started
|
||||
|
||||
Complete the following [guided tutorial](/lessons/digi-yoyo/activity), your code should look like this:
|
||||
|
||||
|
||||
```blocks
|
||||
let count = 0;
|
||||
while (count < 10) {
|
||||
basic.pause(100);
|
||||
basic.showNumber(count);
|
||||
count = count + 1;
|
||||
basic.pause(20);
|
||||
}
|
||||
```
|
||||
|
||||
### Challenge 1
|
||||
|
||||
How about we create a counter that counts backwards from 10 to 1? Let's add a while loop that executes only when `count` is greater than 0.
|
||||
|
||||
|
||||
```blocks
|
||||
let count = 0;
|
||||
while (count < 10) {
|
||||
basic.pause(100);
|
||||
basic.showNumber(count);
|
||||
count = count + 1;
|
||||
basic.pause(20);
|
||||
}
|
||||
while (count > 0) {
|
||||
|
||||
}
|
||||
|
||||
|
||||
```
|
||||
|
||||
|
||||
### Challenge 2
|
||||
|
||||
Inside of the while loop, let's add `pause->(1000)` so that we have a pause between each number as it's counting down. Also, let's show `count`!
|
||||
|
||||
|
||||
|
||||
```blocks
|
||||
let count = 0;
|
||||
while (count < 10) {
|
||||
basic.pause(100);
|
||||
basic.showNumber(count);
|
||||
count = count + 1;
|
||||
}
|
||||
while (count > 0) {
|
||||
basic.pause(100);
|
||||
basic.showNumber(count);
|
||||
}
|
||||
```
|
||||
|
||||
|
||||
* Run the code to see if it works as expected.
|
||||
|
||||
### Challenge 3
|
||||
|
||||
Now, we need `count` to decrease by one after the micro:bit has displayed the value of `count`.
|
||||
|
||||
We can do this by adding this line:
|
||||
|
||||
```blocks
|
||||
let count = 0;
|
||||
count = count + (count - 1);
|
||||
|
||||
```

# flashing heart blocks activity
|
||||
|
||||
Control images with a variable.
|
||||
|
||||
### ~avatar avatar
|
||||
|
||||
In this activity, you will learn how to blink an image on the LED screen.
|
||||
|
||||
### ~
|
||||
|
||||
Let's start by adding code that plots a heart image on the screen using `show LEDs`. Once you are done coding, don't forget to run your code in the simulator or the micro:bit.
|
||||
|
||||
|
||||
```blocks
|
||||
basic.showLeds(`
|
||||
. # . # .
|
||||
# # # # #
|
||||
# # # # #
|
||||
. # # # .
|
||||
. . # . .`);
|
||||
```
|
||||
|
||||
We want to leave the image on the screen for 0.5 seconds (500 milliseconds), then clear the screen. We can use `pause` to wait and `clear screen` to turn off the LEDs.
|
||||
|
||||
|
||||
```blocks
|
||||
basic.forever(() => {
|
||||
basic.showLeds(`
|
||||
. # . # .
|
||||
# # # # #
|
||||
# # # # #
|
||||
. # # # .
|
||||
. . # . .
|
||||
`)
|
||||
basic.pause(500)
|
||||
basic.clearScreen()
|
||||
})
|
||||
|
||||
|
||||
```
|
||||
|
||||
|
||||
Finally, we can surround this code with a `forever` loop to repeat it and add a pause after `clear screen` to keep the screen off for a little while. Modify your code so that your code looks like this.
|
||||
|
||||
|
||||
```blocks
|
||||
basic.forever(() => {
|
||||
basic.showLeds(`
|
||||
. # . # .
|
||||
# # # # #
|
||||
# # # # #
|
||||
. # # # .
|
||||
. . # . .
|
||||
`)
|
||||
basic.pause(500)
|
||||
basic.clearScreen()
|
||||
basic.pause(500)
|
||||
|
||||
})
|
||||
|
||||

# flashing heart blocks challenges
|
||||
|
||||
Coding challenges for the flashing heart tutorial.
|
||||
|
||||
## Before we get started
|
||||
|
||||
Complete the [flashing heart](/lessons/flashing-heart/activity) activity and your code will look like this:
|
||||
|
||||
```blocks
|
||||
basic.forever(() => {
|
||||
basic.showLeds(`
|
||||
. # . # .
|
||||
# # # # #
|
||||
# # # # #
|
||||
. # # # .
|
||||
. . # . .
|
||||
`)
|
||||
basic.pause(500)
|
||||
basic.clearScreen()
|
||||
basic.pause(500)
|
||||
|
||||
})
|
||||
```
|
||||
|
||||
|
||||
### Challenge 1
|
||||
|
||||
Let's plot a different image. Let's display a broken heart!
|
||||
|
||||
To do this, you need to add a block between the last line and the end loop. Add a `show LEDs` block and then add a `pause` of 500 milliseconds.
|
||||
|
||||
|
||||
```blocks
|
||||
basic.forever(() => {
|
||||
basic.showLeds(`
|
||||
. # . # .
|
||||
# # # # #
|
||||
# # # # #
|
||||
. # # # .
|
||||
. . # . .
|
||||
`)
|
||||
basic.pause(500)
|
||||
basic.clearScreen()
|
||||
basic.pause(500)
|
||||
basic.showLeds(`
|
||||
. # . # .
|
||||
# . # # #
|
||||
# . . # #
|
||||
. # # # .
|
||||
. . # . .
|
||||
`)
|
||||
basic.pause(500)
|
||||
})
|
||||
```
|
||||
|
||||
|
||||
* click *run main* to see if the code works as expected.
|
||||
|
||||
### Challenge 2
|
||||
|
||||
Now let's alternate flashing the heart and the broken heart. To do this, we need to add a `clear screen` block and then add a `pause` block of 500 milliseconds under the new code we added in Challenge 1.
|
||||
|
||||
|
||||
```blocks
|
||||
basic.forever(() => {
|
||||

# game counter activity
|
||||
|
||||
Have you ever tried to create a game counter? The concept is fairly simply: increase the game `score` with `on button pressed` .
|
||||
|
||||
Let's start by adding `on button (A) pressed` will run each time the user presses A. Let's add a line of code that increments `score` by `1`.
|
||||
|
||||
```blocks
|
||||
input.onButtonPressed(Button.A, () => {
|
||||
game.addScore(1);
|
||||
});
|
||||
```
|
||||
|
||||
|
||||
Let's add a `add points to score` block to keep track of the current count. Since the count will change with the `add points to score` blocks, add a game block `score` to display the count on screen.
|
||||
|
||||
|
||||
|
||||
```blocks
|
||||
input.onButtonPressed(Button.A, () => {
|
||||
game.addScore(1);
|
||||
basic.showNumber(game.score())
|
||||
});

basic.showNumber(game.score())
|
||||
});
|
||||
```
|
||||
|
||||
### Challenge 1
|
||||
|
||||
Let's add the code to `score` when `B` is pressed. Add an event handler with `on button (B) pressed` then add the code to `score`.
|
||||
|
||||
|
||||
```blocks
|
||||
input.onButtonPressed(Button.A, () => {

# glowing pendulum block activity
|
||||
|
||||
Construct a pendulum that glows using acceleration.
|
||||
|
||||
Welcome! This activity will teach how to construct a pendulum that glows using acceleration. Let's get started!
|
||||
|
||||
Turn on all the LEDs.
|
||||
|
||||
```blocks
|
||||
basic.showLeds(`
|
||||
# # # # #
|
||||
# # # # #
|
||||
# # # # #
|
||||
# # # # #
|
||||
# # # # #
|
||||
`)
|
||||
```
|
||||
|
||||
Create a **forever** loop that will constantly display the appropriate brightness on the LED display.
|
||||
|
||||
|
||||
```blocks
|
||||
basic.showLeds(`
|
||||
# # # # #
|
||||
# # # # #
|
||||
# # # # #
|
||||
# # # # #
|
||||
# # # # #
|
||||
`)
|
||||
basic.forever(() => {
|
||||
|
||||
})
|
||||
```
|
||||
|
||||
Now let's measure the acceleration on the `y` axis and store that value in a variable. The `acceleration(y)` function will provide the value.
|
||||
|
||||
```blocks
|
||||
basic.showLeds(`
|
||||
# # # # #
|
||||
# # # # #
|
||||
# # # # #
|
||||
# # # # #
|
||||
# # # # #
|
||||
`)
|
||||
basic.forever(() => {
|
||||
let acceleration = input.acceleration(Dimension.Y);
|
||||
});
|
||||
```
|
||||
|
||||
Since the micro:bit will be swinging back and forth, the acceleration will only be positive half of the time. Thus, to always get a positive value, we want to take the absolute value of the acceleration.
|
||||
|
||||
|
||||
```blocks
|
||||
basic.showLeds(`
|
||||
# # # # #
|
||||
# # # # #
|
||||
# # # # #
|
||||
# # # # #
|
||||
# # # # #
|
||||
`)
|
||||
basic.forever(() => {
|
||||
let acceleration = input.acceleration(Dimension.Y);
|
||||
acceleration = Math.abs(acceleration)
|
||||
});
|
||||
```
|
||||
|
||||
The function `acceleration(y)` returns a number between 0 and 1024. We want to use this value for the brightness of the micro:bit, but the `set brightness()` only accepts a value between 0 and 256. Thus, we need to divide the acceleration by 4 to ensure we will be in the appropriate range.
|
||||
|
||||
```blocks
|
||||
basic.showLeds(`
|
||||
# # # # #
|
||||
# # # # #
|
||||
# # # # #
|
||||
# # # # #
|
||||
# # # # #
|
||||
`)
|
||||
basic.forever(() => {
|
||||
let acceleration = input.acceleration(Dimension.Y);
|
||||
acceleration = Math.abs(acceleration);
|
||||
acceleration = acceleration / 4;
|
||||
});
|
||||
|
||||
```
|
||||
|
||||
Now let's use our acceleration value to set the brightness on the micro:bit.
|
||||
|
||||
```blocks
|
||||
basic.showLeds(`
|
||||
# # # # #

|
||||
basic.forever(() => {
|
||||
let acceleration = input.acceleration(Dimension.Y);
|
||||
acceleration = Math.abs(acceleration);
|
||||
acceleration = acceleration / 4;
|

led.setBrightness(acceleration)

Coding challenges for the glowing pendulum tutorial.
|
||||
|
||||
## Before we get started
|
||||
|
||||
Complete the following [glowing pendulum activity](/lessons/glowing-pendulum/activity) and your code should look like this:
|
||||
|
||||
```blocks
|
||||
basic.forever(() => {
|
||||
let acceleration = input.acceleration(Dimension.Y);
|
||||
acceleration = Math.abs(acceleration);

```
|
||||
|
||||
### Challenge 1
|
||||
|
||||
|
||||
|
||||
Hold the micro:bit in your hand in a dark room. Move the micro:bit like a pendulum and produce a slow image that captures the pattern of the micro:bit LEDs.
|
||||
|
||||
### Challenge 2
|
||||
|
||||
Replace "y" in `acceleration(y)` with "x" or "z". Changing the axis will cause the micro:bit to measure the force in a different direction. What differences in the resulting pattern does this replacement make?

* all LEDs are turned on
|
||||
* the BBC micro:bit repeats code **forever** that
|
||||
* reads the acceleration along the ``y`` axis,
|
||||
* calculate the absolute value of the acceleration
|
||||
* scales down the acceleration value by a factor of `4`
|
||||
* uses the scaled value to set the screen **brightness**

# blocks - rendering graphics
|
||||
|
||||
An introduction to graphics for the Block Editor.
|
||||
|
||||
## Before we get started
|
||||
|
||||
Ensure you have completed the 'Hello, world!' and Loop tutorials and tested them on a simulator or on BBC micro:bit.
|
||||
|
||||
|
||||
|
||||
The BBC micro:bit has a grid of 25 LEDs, so we can use these to display images.
|
||||
|
||||
We’ve already experimented with the `show string` block that displays a string (some text) that we program it to. However we can use more blocks from the **Images** drawer to render or display images in different ways.
|
||||
|
||||
### Pixel Art
|
||||
|
||||
We can draw little images from the LEDs by ticking boxes. Drag a `show image` block from the **Images** drawer and connect in a `create image` block. You can customize this image by clicking boxes to tick whether the LED will turn on or off. For example, if we were creating a music player we may want to the show the `play` block:
|
||||
|
||||
|
||||
|
||||
### Plotting points
|
||||
|
||||
We can also code our bug to plot a point by giving an x (horizontal) and y (vertical) coordinates, from 0 to 4. Click the **LED** drawer and drag a `plot` block. Try changing the coordinates and see the effect this has on the BBC micro:bit.
|
||||
|
||||
We can also unplot a point (turn the LED off again) using the `unplot` block. So we could create a flashing LED program, using the `pause` block to create a delay.
|
||||
|
||||
|
||||
|
||||
We can also use the `clear screen` block to turn off all LEDs.
|
||||
|
||||
## Tip
|
||||
|
||||
The pause block is in milliseconds, so setting it to 1000 will have a pause of a single second.
|
||||
|
||||
### Devising algorithms for shapes
|
||||
|
||||
An algorithm is a set of steps to follow to solve a problem. We can begin to draw shapes on the BBC micro:bit using an algorithm. For example, we could draw a straight line with this code:
|
||||
|
||||
|
||||
|
||||
Our algorithm is: increase **i** by 1 **from 0** to **4**, and **plot** the point **x=i**, **y=0**. The pause block allows this line to be animated (drawn frame by frame).
|
||||
|
||||
Try devising an algorithm for a diagonal line using the code above and the variable **i**. Your code should look like this; as our variable increases, so does the location that the BBC micro:bit is plotting at:
|
||||
|
||||
|
||||
|
||||
We can create more complex algorithms for more complex shapes, too. See the [challenges](/lessons/challenges) section for additional graphical challenges and solutions.
|
||||
|
||||
### Animations
|
||||
|
||||
Animations are changes happening at a certain rate. For example, we could add the `delay` block from the **Basic** drawer with our square algorithm – this will slowly draw a square (as an animation).
|
||||
|
||||
We could create more complex animations, for example we could make our BBC micro:bit display an explosion or fireworks.
|
||||
|
||||
See the [challenges](/lessons/challenges) section for some animation tasks.
|
||||
|
||||
### Image variables
|
||||
|
||||
We can create image variables so we can easily display an image at a later point. For example:
|
||||
|
||||
|
||||
|
||||
This uses the blocks from the **Variable** drawer, and the **create image** block from the **Image** drawer. This means our image can be displayed without having to replicate the `create image` block each time.

# guess the number quiz answers
|
||||
|
||||
Learn how to generate a random number on the micro:bit.
|
||||
|
||||
This is the answer key for the [guess the number quiz](/lessons/guess-the-number/quiz).
|
||||
|
||||
## 1. What is on button pressed?
|
||||
|
||||
Answers may vary. Generally, on button pressed run code when an input button is pressed. The micro:bit has two input buttons: A and B.
|
||||
|
||||
## 2. Consider the following directions
|
||||
|
||||
Write the line of code that creates a condition when the BBC micro:bit button A is pressed.
|
||||
|
||||
|
||||
```blocks
|
||||
input.onButtonPressed(Button.A, () => {
|
||||
})
|
||||
```
|
||||
|
||||
## 3. Write the line of code that creates a **local variable** and a **random number**.
|
||||
|
||||
|
||||
|
||||
|
||||
```blocks
|
||||
let randomNumber = Math.random(10)
|
||||
```
|
||||
|
||||
## 4.
|
||||
If the rectangle below represents the BBC micro:bit, shade the areas that will be displayed. Explain why that particular area is shaded.
|
||||
|
||||
```blocks
|
||||
let randomNumber = Math.random(10)
|
||||
```
|
||||
|
||||
|
||||
|
||||
|
||||
The random number generator will return a number from 0 to the limit. However, not including the limit unless the limit is 0. So you can place an X to represent any single digit number.

# happy birthday blocks activity
|
||||
|
||||
Play sounds with music blocks.
|
||||
|
||||
Have you ever tried to play a song on an instrument? Let's try coding the song "Happy Birthday" on the micro:bit !
|
||||
|
||||
Let's start by adding the code in the music drawer that includes a single musical chord (or pitched sound) with the `play` block. Then insert the chord "C". Once you are done coding, don't forget to run your code in the simulator or the micro:bit.
|
||||
|
||||
```blocks
|
||||
music.playTone(music.noteFrequency(Note.C), music.beat(BeatFraction.Quater));
|
||||
```
|
||||
|
||||
* click run to see if the code works as expected.
|
||||
|
||||
We want to continue to adding musical chords with the `play` block. So insert the appropriate chord blocks: `D`, `F`, `G` to complete the first part of the song. Modify your code so that your code looks like this.
|
||||
|
||||
```blocks
|
||||
music.playTone(music.noteFrequency(Note.C), music.beat(BeatFraction.Quater));
|
||||
music.playTone(music.noteFrequency(Note.C), music.beat(BeatFraction.Quater));
|
||||
music.playTone(music.noteFrequency(Note.D), music.beat(BeatFraction.Quater));
|
||||
music.playTone(music.noteFrequency(Note.C), music.beat(BeatFraction.Quater));
|
||||
music.playTone(music.noteFrequency(Note.F), music.beat(BeatFraction.Quater));
|
||||
music.playTone(music.noteFrequency(Note.E), music.beat(BeatFraction.Quater));
|
||||
basic.pause(100);
|
||||
```
|
||||
|
||||
* click run to see if the code works as expected.
|
||||
|
||||
We want to continue to adding musical chords with the `play` block. Then insert the appropriate chords: `B`, `C`, `D`, `E` , `F` to complete the second part of the song. Modify your code so that your code looks like this.
|
||||

||||
### Challenge 2
|
||||
|
||||
Finally, we continue to adding the appropriate `play` block and fit the following chords blocks `F`, `E`, `C`, `D` to complete the third part of the song. Modify your code so that your code looks like this.
|
||||
|
||||
|
||||
```blocks

## Prior learning/place of lesson in scheme of work
|
||||
|
||||
Learn how to create a charades game with **collections**, ` create -> Collection of` , to store and retrieve data . We will be learning how to create a charades game using global variables, collection of string, add, Boolean, on logo down, on logo up, forever loop, if statements, running time as well as simple commands, such as show string and show number.

# headbands activity
|
||||
|
||||
## Before we get started
|
||||
|
||||
Your beginning code should look like this:
|
||||
|
||||
```blocks
|
||||
let coll = (<string[]>[])
|
||||
coll.push("puppy")
|
||||
coll.push("clock")
|
||||
coll.push("night")
|
||||
coll.push("cat")
|
||||
coll.push("cow")
|
||||
input.onLogoUp(() => {
|
||||
let index = Math.random(coll.length)
|
||||
let word = coll[index]
|
||||
basic.showString(word, 150)
|
||||
})
|
||||
input.onScreenDown(() => {
|
||||
game.addScore(1)
|
||||
})
|
||||
game.startCountdown(30000)
|
||||
```
|
||||
|
||||
### Challenge 1
|
||||
|
||||
Let's add more words for the player to act out! But first, we need to increase the time in one round to give the player more time get through all the words. Let's change the `game->start countdown` statement.
|
||||
|
||||
```blocks
|
||||
let coll = (<string[]>[])
|
||||
coll.push("puppy")
|
||||
coll.push("clock")
|
||||
coll.push("night")
|
||||
coll.push("cat")
|
||||
coll.push("cow")
|
||||
input.onLogoUp(() => {
|
||||
let index = Math.random(coll.length)
|
||||
let word = coll[index]
|
||||
basic.showString(word, 150)
|
||||
})
|
||||
input.onScreenDown(() => {
|
||||
game.addScore(1)
|
||||
})
|
||||
|
||||
game.startCountdown(60000)
|
||||
```
|
||||
|
||||
* Run your code to see if it works as expected
|
||||
|
||||
### Challenge 2
|
||||
|
||||
Now let's add 5 more words to our list of charade words. Right above the the line `word:=coll->at(index)` add 5 lines that say `coll->add("")`. In this example, we will add the words **bicycle, telephone, sun, car, and ant** but you can add whatever words you like.
|
||||
|
||||
```blocks
|
||||
let coll.push("puppy")
|
||||
coll.push("clock")
|
||||
coll.push("night")
|
||||
coll.push("cat")
|
||||
coll.push("cow")
|
||||
coll.push("bicycle")
|
||||
coll.push("telephone")
|
||||
coll.push("sun")
|
||||
coll.push("car")
|
||||
coll.push("ant")
|
||||
input.onLogoUp(() => {
|
||||
let index = Math.random(coll.length)
|
||||
let word = coll[index]
|
||||
basic.showString(word, 150)
|
||||
})
|
||||
input.onScreenDown(() => {
|
||||
game.addScore(1)
|
||||
})
|
||||
game.startCountdown(30000)
|
||||
```
|
||||
|
||||
* Run your code to see if it works as expected.
|
||||
|
||||
### Challenge 3
|
||||
|
||||
Remove a life using `game->remove life` when the screen is down using the `input->on screen down` event.
|
||||
|
||||
### Challenge 4
|
||||
|
||||
The collection has a function `random` that returns a random element. Update your code to use this function instead of using `math->random`.
|
||||
|
||||
### Challenge 5!
|
||||
|
||||
Play the game and try guessing all these words in less than 2 minutes!

# hero
|
||||
|
||||
A classic game, Hero, in which you must capture the food and flee away from the ghost!
|
||||
|
||||
### ~avatar avatar
|
||||
|
||||
This tutorial will teach you how to create a hero game to capture food while dodging the ghost; the game was inspired by the classic arcade game Pac Man.
|
||||
|
||||
### ~
|
||||
|
||||
First we need to create a function create sprite at the x, y coordinates and that set the variable called hero on the micro:bit the first time we play.
|
||||
|
||||
|
||||
```blocks
|
||||
|
||||
let hero = game.createSprite(2, 2)
|
||||
|
||||
```
|
||||
|
||||
Let's set up where we want our ghost will be. Create starting positions of the hero, ghost, and food in each individual quadrant. We will ensure that the ghost, food, and hero is set apart. Divide the micro:bit into 4 quadrants. We don't want hero to be too close to the ghost so let's make the ghost starting positions in the 3 other quadrants. Hero is in the one quadrant. To do this, we need to keep track of the middle point in each quadrant. Create sprite at the x, y coordinates for the hero, food, and ghost.
|
||||
|
||||
```blocks
|
||||
let hero = game.createSprite(2, 2)
|
||||
let food = game.createSprite(4, 4)
|
||||
let ghost = game.createSprite(0, 0)
|
||||
```
|
||||
|
||||
|
||||
Create a function called change blink that will plot a blinking point so the player can tell between a ghost and hero.
|
||||
|
||||
```blocks
|
||||
let hero = game.createSprite(2, 2);
|
||||
let food = game.createSprite(4, 4);
|
||||
let ghost = game.createSprite(0, 0);
|
||||
ghost.change(LedSpriteProperty.Blink, 100);
|
||||
|
||||
```
|
||||
|
||||
|
||||
We want to identify the food so the player moves towards the food. We need to set the `brightness` of the `variable` food to 8. The brightness of the LED screen is expressed as a number between 0 and 255.
|
||||
|
||||
```blocks
|
||||
let hero = game.createSprite(2, 2);
|
||||
let food = game.createSprite(4, 4);
|
||||
let ghost = game.createSprite(0, 0);
|
||||
ghost.change(LedSpriteProperty.Blink, 100);
|
||||
food = led.brightness() == 8;
|
||||
|
||||
```
|
||||
|
||||
We want to include a block from the Loops drawer called `While`. Then set the `While` loop to `true`. This code will be important for repeating code of the game logic of the game. The game will continue to run using `While` loop while the Boolean condition is true. Finally, include a `pause` of 400 milliseconds before the logic of the game begins.
|
||||
|
||||
|
||||
```blocks
|
||||
let hero = game.createSprite(2, 2);
|
||||
let food = game.createSprite(4, 4);
|
||||
let ghost = game.createSprite(0, 0);
|
||||
ghost.change(LedSpriteProperty.Blink, 100);
|
||||
food = led.brightness() == 8;
|
||||
while (true) {
|
||||
basic.pause(400);
|
||||
}
|
||||
|
||||
|
||||
```
|
||||
|
||||
Let's create a function that will take care of keep the ghost pursuing the hero. We will need to a conditional statement that checks the position of the ghost and hero. The first condition will check if the horizontal coordinates of the ghost is less than the horizontal coordinates of the hero. We create a function from the Game drawer that will check the coordinates of the hero and the ghost. Finally, change the x-direction of the ghost by 1.
|
||||
|
||||
Then create another function that will take care of keep the ghost pursuing the hero. We will need to a conditional statement that checks the position of the ghost and hero. The second condition will check if the horizontal coordinates of the ghost is greater than the x-direction of hero. We create a function from the Game drawer that will check the x-direction of hero and ghost. Finally, change the x-direction of the ghost by -1.
|
||||
|
||||
```blocks
|
||||
let hero = game.createSprite(2, 2);
|
||||
let food = game.createSprite(4, 4);
|
||||
let ghost = game.createSprite(0, 0);
|
||||
ghost.change(LedSpriteProperty.Blink, 100);
|
||||
food = led.brightness() == 8;
|
||||
while (true) {
|
||||
basic.pause(400);
|
||||
if (ghost.get(LedSpriteProperty.X) < hero.get(LedSpriteProperty.X)) {
|
||||
ghost.change(LedSpriteProperty.X, 1);
|
||||
}
|
||||
else if (ghost.get(LedSpriteProperty.X) > hero.get(LedSpriteProperty.X)) {
|
||||
ghost.change(LedSpriteProperty.X, -1 );
|
||||
}
|
||||
else if (false) {
|
||||
}
|
||||
else if (false) {
|
||||
}
|
||||
|
||||
}
|
||||
|
||||
|
||||
```
|
||||
|
||||
Let's create the third function and forth function that continues the same logic in the y-direction of pacman and ghost. We create a function from the Game drawer that will check the y-direction of pacman and ghost. Finally, change the y-direction of the ghost to continue following pacman.
|
||||
|
||||
```blocks
|
||||
let hero = game.createSprite(2, 2);
|
||||
let food = game.createSprite(4, 4);
|
||||
let ghost = game.createSprite(0, 0);
|
||||
ghost.change(LedSpriteProperty.Blink, 100);
|
||||
food = led.brightness() == 8;
|
||||
while (true) {
|
||||
basic.pause(400);
|
||||
if (ghost.get(LedSpriteProperty.X) < hero.get(LedSpriteProperty.X)) {
|
||||
ghost.change(LedSpriteProperty.X, 1);
|
||||
}
|
||||
else if (ghost.get(LedSpriteProperty.X) < hero.get(LedSpriteProperty.X)) {
|
||||
ghost.change(LedSpriteProperty.X, -1 );
|
||||
}
|
||||
else if (ghost.get(LedSpriteProperty.Y) < hero.get(LedSpriteProperty.Y)) {
|
||||
ghost.change(LedSpriteProperty.Y, 1);
|
||||
}
|
||||
else if (ghost.get(LedSpriteProperty.Y) > hero.get(LedSpriteProperty.Y)) {
|
||||
ghost.change(LedSpriteProperty.Y, -1 );
|
||||
}
|
||||
|
||||
}
|
||||
|
||||
|
||||
```
|
||||
|
||||
Let's enable pacman to move in the x-direction and move in the y-direction with acceleration using the micor:bit sensor
|
||||
|
||||
```blocks
|
||||
let hero = game.createSprite(2, 2);
|
||||
let food = game.createSprite(4, 4);
|
||||
let ghost = game.createSprite(0, 0);
|
||||
ghost.change(LedSpriteProperty.Blink, 100);
|
||||
food = led.brightness() == 8;
|
||||
while (true) {
|
||||
basic.pause(400);
|
||||
if (ghost.get(LedSpriteProperty.X) < hero.get(LedSpriteProperty.X)) {
|
||||
ghost.change(LedSpriteProperty.X, 1);
|
||||
}
|
||||
else if (ghost.get(LedSpriteProperty.X) < hero.get(LedSpriteProperty.X)) {
|
||||
ghost.change(LedSpriteProperty.X, -1 );
|
||||
}
|
||||
else if (ghost.get(LedSpriteProperty.Y) < hero.get(LedSpriteProperty.Y)) {
|
||||
ghost.change(LedSpriteProperty.Y, 1);
|
||||
}
|
||||
else if (ghost.get(LedSpriteProperty.Y) > hero.get(LedSpriteProperty.Y)) {
|
||||
ghost.change(LedSpriteProperty.Y, -1 );
|
||||
}
|
||||
if (input.acceleration(Dimension.X) > 200) {
|
||||
hero.change(LedSpriteProperty.X, 1);
|
||||
}
|
||||
else if (input.acceleration(Dimension.X) < -200 ) {
|
||||
hero.change(LedSpriteProperty.X, -1 );
|
||||
}
|
||||
if (input.acceleration(Dimension.Y) > 200) {
|
||||
hero.change(LedSpriteProperty.Y, 1);
|
||||
}
|
||||
else if (input.acceleration(Dimension.Y) > -200 ) {
|
||||
hero.change(LedSpriteProperty.Y, -1 );
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
Let's setup the logic for the food. If hero is `touching` "food", increase the score of the game by 1 and `set` ``x`` -direction of food randomly randomly from 0 to 4 and `set` ``y``-direction of food randomly from 0 to 4.
|
||||
|
||||
```blocks
|
||||
let hero = game.createSprite(2, 2);
|
||||
let food = game.createSprite(4, 4);
|
||||
let ghost = game.createSprite(0, 0);
|
||||
ghost.change(LedSpriteProperty.Blink, 100);
|
||||
food = led.brightness() == 8;
|
||||
while (true) {
|
||||
basic.pause(400);
|
||||
if (ghost.get(LedSpriteProperty.X) < hero.get(LedSpriteProperty.X)) {
|
||||
ghost.change(LedSpriteProperty.X, 1);
|
||||
}
|
||||
else if (ghost.get(LedSpriteProperty.X) < hero.get(LedSpriteProperty.X)) {
|
||||
ghost.change(LedSpriteProperty.X, -1 );
|
||||
}
|
||||
else if (ghost.get(LedSpriteProperty.Y) < hero.get(LedSpriteProperty.Y)) {
|
||||
ghost.change(LedSpriteProperty.Y, 1);
|
||||
}
|
||||
else if (ghost.get(LedSpriteProperty.Y) > hero.get(LedSpriteProperty.Y)) {
|
||||
ghost.change(LedSpriteProperty.Y, -1 );
|
||||
}
|
||||
if (input.acceleration(Dimension.X) > 200) {
|
||||
hero.change(LedSpriteProperty.X, 1);
|
||||
}
|
||||
else if (input.acceleration(Dimension.X) < -200 ) {
|
||||
hero.change(LedSpriteProperty.X, -1 );
|
||||
}
|
||||
if (input.acceleration(Dimension.Y) > 200) {
|
||||
hero.change(LedSpriteProperty.Y, 1);
|
||||
}
|
||||
else if (input.acceleration(Dimension.Y) > -200 ) {
|
||||
hero.change(LedSpriteProperty.Y, -1 );
|
||||
}
|
||||
if (hero.isTouching(food)) {
|
||||
game.addScore(1);
|
||||
food.set(LedSpriteProperty.X, Math.random(5));
|
||||
food.set(LedSpriteProperty.Y, Math.random(5));
|
||||
}
|
||||
|
||||
}
|
||||
|
||||
|
||||
```
|
||||
|
||||
|
||||
|
||||
Let's setup the logic for the food and the ghost to be in different quadrants. Finally, the game over component is now upon the game. If the hero is `touching` the ghost, let's display `game over`
|
||||
|
||||
```blocks
|
||||
|
||||
let hero = game.createSprite(2, 2);
|
||||
let food = game.createSprite(4, 4);
|
||||
let ghost = game.createSprite(0, 0);
|
||||
let ghost.change(LedSpriteProperty.Blink, 100);
|
||||
food = led.brightness() == 8;
|
||||
while (true) {
|
||||
basic.pause(400);
|
||||
if (ghost.get(LedSpriteProperty.X) < hero.get(LedSpriteProperty.X)) {
|
||||
ghost.change(LedSpriteProperty.X, 1);
|
||||
}
|
||||
else if (ghost.get(LedSpriteProperty.X) < hero.get(LedSpriteProperty.X)) {
|
||||
ghost.change(LedSpriteProperty.X, -1 );
|
||||
}
|
||||
else if (ghost.get(LedSpriteProperty.Y) < hero.get(LedSpriteProperty.Y)) {
|
||||
ghost.change(LedSpriteProperty.Y, 1);
|
||||
}
|
||||
else if (ghost.get(LedSpriteProperty.Y) > hero.get(LedSpriteProperty.Y)) {
|
||||
ghost.change(LedSpriteProperty.Y, -1 );
|
||||
}
|
||||
if (input.acceleration(Dimension.X) > 200) {
|
||||
hero.change(LedSpriteProperty.X, 1);
|
||||
}
|
||||
else if (input.acceleration(Dimension.X) < -200 ) {
|
||||
hero.change(LedSpriteProperty.X, -1 );
|
||||
}
|
||||
if (input.acceleration(Dimension.Y) > 200) {
|
||||
hero.change(LedSpriteProperty.Y, 1);
|
||||
}
|
||||
else if (input.acceleration(Dimension.Y) > -200 ) {
|
||||
hero.change(LedSpriteProperty.Y, -1 );
|
||||
}
|
||||
if (hero.isTouching(food)) {
|
||||
game.addScore(1);
|
||||
food.set(LedSpriteProperty.X, Math.random(5));
|
||||
food.set(LedSpriteProperty.Y, Math.random(5));
|
||||
if (food.get(LedSpriteProperty.X) < 2 && food.get(LedSpriteProperty.Y) < 2) {
|
||||
ghost.set(LedSpriteProperty.X, 4);
|
||||
ghost.set(LedSpriteProperty.Y, 4);
|
||||
}
|
||||
else if (food.get(LedSpriteProperty.X) > 2 && food.get(LedSpriteProperty.Y) < 2) {
|
||||
ghost.set(LedSpriteProperty.X, 0);
|
||||
ghost.set(LedSpriteProperty.Y, 4);
|

}
|

# looper blocks activity
|
||||
|
||||
Welcome! This activity will teach how to display a series of numbers for a for loop. Let's get started!
|
||||
|
||||
Let's create a for loop where `0` is the loop's starting value, `i` is the index variable, and `5` is the ending value. The index variable `i` starts at 0 and increases by 1 each time through the loop. The loop ends when `i = 5`.
|
||||
|
||||
|
||||
```blocks
|
||||
for (let i = 0; i < 6; i++) {
|
||||
|
||||
}
|
||||
```
|
||||
|
||||
We will show the number of times the loop has been executed. It will go from zero to five times.
|
||||
|
||||
```blocks
|
||||
for (let i = 0; i < 6; i++) {
|
||||
basic.showNumber(i)
|
||||
}
|
||||
```
|
||||
|
||||
The for loop while cycle through to six immediately unless we pause for a little bit in between each loop.
|
||||
|
||||
```blocks
|
||||
for (let i = 0; i < 6; i++) {
|
||||
basic.showNumber(i)
|
||||
basic.pause(2000)
|
||||
}
|
||||
```

# looper block challenges
|
||||
|
||||
Coding challenges for the looper.
|
||||
|
||||
## Before we get started
|
||||
|
||||
Complete the following guided activity:
|
||||
|
||||
* [activity](/lessons/looper/activity)
|
||||
|
||||
At the end of the activity, your code should look like this:
|
||||
|
||||
|
||||
```blocks
|
||||
for (let i = 0; i < 6; i++) {
|
||||
basic.showNumber(i)
|
||||
basic.pause(2000)
|
||||
}
|
||||
```
|
||||
|
||||
### Challenge 1
|
||||
|
||||
What if we want to count up to lucky number 7 instead? Let's do that by changing the ending value to `7` instead of `5`.
|
||||
|
||||
|
||||
```blocks
|
||||
for (let i = 0; i < 8; i++) {
|
||||
basic.showNumber(i)
|
||||
basic.pause(2000)
|
||||
}
|
||||
|
||||
```
|
||||
|
||||
* Run the program now to see your changes.
|
||||
|
||||
### Challenge 2
|
||||
|
||||
What about 9? Let's do that by changing the ending value to `9`.
|
||||
|
||||
```blocks
|
||||
for (let i = 0; i < 10; i++) {
|
||||
basic.showNumber(i)
|
||||
basic.pause(2000)
|
||||
}
|
||||
|
||||
|
||||
```
|
||||
|
||||
|
||||
* Run your code to see the new counter.
|
||||
|
||||
### Challenge 3
|
||||
|
||||
Now let's start counting from `3` instead! Our for loop will always start at `0` so we simply add `3` to the `i` variable when passing it to `show number`.
|
||||
|
||||
```blocks
|
||||
for (let i = 0; i < 10; i++) {
|
||||
basic.showNumber(i+3)
|
||||
basic.pause(2000)
|
||||
}
|
||||
|
||||
|
||||
```
|
||||
|
||||
Run it on the simulator!
|
||||
|
||||
### Challenge 4
|
||||
|
||||
Now, let's **count down from 9**. Change the line `show number(i + 2, 150)` to `show number(9 - i, 150)`.
|
||||
|
||||
```blocks
|
||||
for (let i = 0; i < 10; i++) {
|
||||
basic.showNumber(9-i)
|
||||
basic.pause(2000)
|
||||
}
|
||||
|
||||
```
|
||||
|
||||
|
||||
* Run the code to make sure it is doing what is expected.
|
||||
|
||||
### Challenge 5
|
||||
|
||||
After counting down from `9` let's show the string `BOOOM`!

# looper quiz answers
|
||||
|
||||
Learn how to create a series of numbers with a for loop.
|
||||
|
||||
This is the answer key for the [looper quiz](/lessons/looper/quiz).
|
||||
|
||||
## 1. What is a for loop?
|
||||
|
||||
Answers will vary. In general, for loop refers to the code that repeats for a fixed number of times. We specify the LED using x, y coordinates.
|
||||
|
||||
## 2. Consider the following code
|
||||
|
||||
```blocks
|
||||
for (let i = 0; i < 4; i++) {
|
||||
basic.showNumber(i, 150)
|
||||
}
|
||||
```
|
||||
|
||||
If the rectangle below represents the BBC micro:bit, shade the areas that will be displayed. Explain why that particular area is shaded.
|
||||
|
||||
Let's create a for loop where `0` is the loop's starting value, `i` is the index variable, and `4` is the ending value. The index variable `i` starts at 0 and increases by 1 each time through the loop. The loop ends when `i = 4`.
|
||||
|
||||
|
||||
|
||||
## 3. Consider the following code
|
||||
|
||||
```blocks
|
||||
for (let i1 = 0; i1 < 6; i1++) {
|
||||
basic.showNumber(i1, 150)
|
||||
}
|
||||
```
|
||||
|
||||
If the rectangle below represents the BBC micro:bit, shade the areas that will be displayed. Explain why that particular area is shaded.
|
||||
|
||||
Let's create a for loop where `0` is the loop's starting value, `i` is the index variable, and `6` is the ending value. The index variable `i` starts at 0 and increases by 1 each time through the loop. The loop ends when `i = 6`.

# blocks - loops
|
||||
|
||||
An introduction to Loops for the Block Editor.
|
||||
|
||||
We may want to handle the user’s input multiple times or remain waiting for their input for a long time. We use loops to make sure that our code runs multiple times. These can be found in the **Loops** drawer.
|
||||
|
||||
### Forever loops
|
||||
|
||||
In the Variables tutorial we utilised a forever loop to create a counter:
|
||||
|
||||
|
||||
|
||||
This allows our BBC micro:bit to wait for the user to do something forever, for example wait for the user to press the correct button as the example above shows. If you were creating a quiz, you may want to loop forever until the user presses the correct button or answers the question.
|
||||
|
||||
### Repeat Loops
|
||||
|
||||
Repeat loops allow code to happen a certain amount of times. You may want to create a quiz that only gives the user a few tries to get the correct answer, for example. The number can be changed to facilitate your code.
|
||||
|
||||
|
||||
|
||||
The code above will scroll the message, “Hello world” three times.
|
||||
|
||||
### While & Until loops
|
||||
|
||||
The ‘repeat while’ loop allows you to continue looping some code until a condition is met. The empty socket next to the while loop allows you to connect some Logic and construct a statement.
|
||||
|
||||
|
||||
|
||||
The code above will scroll the message, “Press it!”, while the user hasn’t pressed the button.
|
||||
|
||||
* Drag a `set item` block from the **Variables** drawer. Click the **down arrow** and click **New Variable**, and type "pressed". Drag a `0` block from **Maths** to set the variable **pressed** to 0.
|
||||
* Drag a `repeat while` block from the **Loops** drawer and attach an `=` block from the **Logic** drawer. Drag `item` from the **Variables** drawer and click the **down arrow**, select ‘pressed’. Drag a `0` block from Maths and connect it to the other side of the equals. This will carry out the code until ‘pressed’ does not equal 0.
|
||||
* Add a `show string` block from the **Basic** drawer and change the message to "Press it!"
|
||||
* Add an `if` block from the **Logic** drawer, connect a `button pressed` block from the **Input** drawer, and add text from the **Basic** drawer. Change this to A to show we are waiting for button A.
|
||||
* Inside the ‘do’ part of the if statement, add a `set` block from the Variables drawer, click the **down arrow** to change it to **pressed** and drag a `1` from the Maths drawer
|
||||
* Lastly underneath the while loop, add another `show string` block and fill in the gaps.
|
||||
|
||||
Test the code above on actual hardware or on the simulator window.
|
||||
|
||||
We can also change the code in subtle ways to have a completely different effect:
|
||||
|
||||
|
||||
|
||||
This time we have to press the button three times to leave the while loop.
|
||||
|
||||
## Tip
|
||||
|
||||
You can press the arrow next to a word in a block to change it. For example, you can change Math functions or change a Logic statement.
|
||||
|
||||
### Count or for loops
|
||||
|
||||
A count loop allows you to loop a certain amount of times and to change a variable as you do so. For example, we can create a simple counting program:
|
||||
|
||||
|
||||
|
||||
The count loop will repeat a certain amount of times whilst changing a variable. You can click the arrow next to **i** to replace it with any of your own variables. So this program will display numbers 1 to 10.
|
||||
|
||||
This loop allows you to repeat code for the amount of times you want to without worrying about manually changing variables. You could use this for a counting program or a timer.

## Prior learning/place of lesson in scheme of work
|
||||
|
||||
Learn how to use the **pin pressed**, `on pin pressed` to run code when the user holds the GND pin with one hand, and presses pin 0 with the other hand, thus completing a circuit. We will be learning how to create a love meter using input on pin pressed, a local variable, math random, If (conditional) as well as simple commands, such as show number, pause, and show string.

# love meter blocks activity
|

|
||||
Create a love meter with the micro:bit
|
||||
|
||||
### ~avatar avatar
|
||||
|
||||
Welcome! This activity will help you create a love meter with the micro:bit. Let's get started!
|
||||
|
||||
### ~
|
||||
|
||||
Begin by registering an event with `on pin pressed` *P0* to know when someone is holding pin *P0* and pin *Gnd*.
|
||||
|
||||
|
||||
```blocks
|
||||
input.onPinPressed(TouchPin.P0, () => {
|
||||
|
||||
})
|
||||
|
||||
```
|
||||
|
||||
We are going to create a meter that displays a random number from *0* to *10*. We use *10* as `random number up to` returns a number between *0* and *n*.
|
||||
|
||||
|
||||
```blocks
|
||||
input.onPinPressed(TouchPin.P0, () => {
|
||||
let x = Math.random(10)
|
||||
})
|
||||
|
||||
```
|
||||
|
||||
Finally, let's show that number on the micro:bit. You are registering an event handler that will execute on the BBC micro:bit whenever the user holds the GND pin with one hand, and presses pin 0 with the other hand, thus completing a circuit
|
||||
|
||||
|
||||
```blocks
|
||||
input.onPinPressed(TouchPin.P0, () => {
|
||||
let x = Math.random(10)
|
||||
basic.showNumber(x)
|
||||
})
|
||||
|
||||
```

# love meter blocks challenges
|
||||
|
||||
Create a love meter with the micro:bit
|
||||
|
||||
## Before we get started
|
||||
|
||||
You should work on these challenges after the following the [love meter activity](/lessons/love-meter/activity)
|
||||
|
||||
```blocks
|
||||
input.onPinPressed(TouchPin.P0, () => {
|
||||
let x = Math.random(10)
|
||||
basic.showNumber(x)
|
||||
})
|
||||
|
||||
```
|
||||
|
||||
### Challenge 1
|
||||
|
||||
Add a pause of 3000 milliseconds (3 seconds) after showing the number so that the number won't immediately disappear in the next challenge.
|
||||
|
||||
|
||||
```blocks
|
||||
input.onPinPressed(TouchPin.P0, () => {
|
||||
let x = Math.random(10)
|
||||
basic.showNumber(x)
|
||||
basic.pause(3000)
|
||||
})
|
||||
```
|
||||
|
||||
### Challenge 2
|
||||
|
||||
If the rating **x** is between *0* and *3* (strictly less than *4*), display the text "HORRIBLE!".
|
||||
|
||||
|
||||
```blocks
|
||||
input.onPinPressed(TouchPin.P0, () => {
|
||||
let x = Math.random(10)
|
||||
basic.showNumber(x)
|
||||
basic.pause(3000)
|
||||
if (x < 4) {
|
||||
basic.showString("HORRIBLE")
|
||||
}
|
||||
})
|
||||
```
|
||||
|
||||
### Challenge 3
|
||||
|
||||
**If** the rating is between 4 and 7, display the text "MEDIOCRE!" **else** display the text "MATCHED!"
|
||||
|
||||
```blocks
|
||||
input.onPinPressed(TouchPin.P0, () => {
|
||||
let x = Math.random(10)
|
||||
basic.showNumber(x)
|
||||
basic.pause(3000)
|
||||
if (x < 4) {
|
||||
basic.showString("HORRIBLE")
|
||||
} else if (x < 8) {
|
||||
basic.showString("MEDIOCRE")
|
||||
} else {
|
||||
basic.showString("MATCHED")
|
||||
}
|
||||
|
||||
})
|
||||
```
|
||||
|
||||
### Challenge 4
|
||||
|
||||
Use `show LEDs` to display images instead of text for each case.

# love meter blocks quiz answers
|
||||
|
||||
The answers to the love meter quiz.
|
||||
|
||||
This is the answer key for the [love meter quiz](/lessons/love-meter/quiz).
|
||||
|
||||
## 1. What does `on pin pressed(P0)` do?
|
||||
|
||||
<br/>
|
||||
|
||||
It's a method that runs code when the user holds the GND pin with a finger of one hand and presses pin P0, completing a circuit.
|
||||
|
||||
## 2. Write the code.
|
||||
|
||||
Create a condition for `on pin pressed (P0)`.
|
||||
|
||||
```blocks
|
||||
input.onPinPressed(TouchPin.P0, () => {
|
||||
|
||||
})
|
||||
```
|
||||
|
||||
## 3. What does this line of code doing?
|
||||
|
||||
```blocks
|
||||
let x = Math.random(9)
|
||||
```
|
||||
|
||||
|
||||
It stores random number between 0 and 9 then stores that number in a variable.
|
||||
|
||||
## 4. Why do you have to add 1 to variable x?
|
||||
|
||||
```blocks
|
||||
let item = 0;
|
||||
item = 0;
|
||||
basic.showNumber(item + 1);
|
||||
```
|
||||
|
||||
You have to add 1 if you want to generate a random number between 1 and 10 .
|
||||
|
||||
## 5. Why do you have to hold ground (GND) to make this work on the micro:bit?
|
||||
|
||||
|
||||
You have told GND to complete the circuit.

```
|
||||
|
||||
### Challenge 1
|
||||
|
||||
But we also should pause before showing another number. Let's add a pause of 500 milliseconds.
|
||||
|
||||
