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)
|
||||
})
|
||||
```
|
||||
|
||||
### Challenge 2
|
||||
|
||||
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
|
||||
0 0 0 0 0
|
||||
0 1 0 1 0
|
||||
0 0 1 0 0
|
||||
1 0 0 0 1
|
||||
0 1 1 1 0
|
||||
````
|
||||
|
||||
### 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
|
||||
|
||||
Create your own image by changing the coordinates in `plot` and `unplot`!
