# compass challenges
|
||||
|
||||
Display the direction that the BBC micro:bit is facing using the compass
|
||||
|
||||
## Before we get started
|
||||
|
||||
Complete the following guided tutorial:
|
||||
|
||||
* [tutorial](/microbit/lessons/compass/tutorial)
|
||||
|
||||
At the end of the tutorial, click `keep editing`. Your code should look like this:
|
||||
|
||||
```
|
||||
input.calibrate()
|
||||
basic.forever(() => {
|
||||
let degrees = input.compassHeading()
|
||||
if (degrees < 45) {
|
||||
basic.showString("N", 100)
|
||||
} else if (degrees < 135) {
|
||||
basic.showString("E", 100)
|
||||
}
|
||||
else if (degrees < 225) {
|
||||
basic.showString("S", 100)
|
||||
}
|
||||
else {
|
||||
basic.showString("W", 100)
|
||||
}
|
||||
})
|
||||
```
|
||||
|
||||
### Challenge 1
|
||||
|
||||
Instead of displaying `N` when the BBC micro:bit is pointing North, display a star to indicate the north star.
|
||||
|
||||
```
|
||||
input.calibrate()
|
||||
basic.forever(() => {
|
||||
let degrees1 = input.compassHeading()
|
||||
if (degrees1 < 45) {
|
||||
basic.plotImage(`
|
||||
# . # . #
|
||||
. # # # .
|
||||
# # # # #
|
||||
. # # # .
|
||||
# . # . #
|
||||
`) // ***
|
||||
} else if (degrees1 < 135) {
|
||||
basic.showString("E", 100)
|
||||
}
|
||||
else if (degrees1 < 225) {
|
||||
basic.showString("S", 100)
|
||||
}
|
||||
else {
|
||||
basic.showString("W", 100)
|
||||
}
|
||||
})
|
||||
```
|
||||
|
||||
* Run your code to see if it works as expected
|
||||
|
||||
### Challenge 2
|
||||
|
||||
Instead of displaying just `N`, `W`, `S`, or `E`, display the full word.
|
||||
|
||||
```
|
||||
input.calibrate()
|
||||
basic.forever(() => {
|
||||
let degrees2 = input.compassHeading()
|
||||
if (degrees2 < 45) {
|
||||
basic.showString("NORTH", 100) // ***
|
||||
} else if (degrees2 < 135) {
|
||||
basic.showString("EAST", 100) // ***
|
||||
}
|
||||
else if (degrees2 < 225) {
|
||||
basic.showString("SOUTH", 100) // ***
|
||||
}
|
||||
else {
|
||||
basic.showString("WEST", 100) // ***
|
||||
}
|
||||
})
|
||||
```
|
||||
|
||||
* Run your code to see if it works as expected
|
||||
|
||||
### Challenge 3
|
||||
|
||||
Display your own unique message for each direction.

# compass quiz answers
|
||||
|
||||
Create an actual compass to show your direction: North, South, East, or West
|
||||
|
||||
## Name
|
||||
|
||||
## Directions
|
||||
|
||||
Use this activity document to guide your work in the [compass tutorial](/microbit/lessons/compass/tutorial).
|
||||
|
||||
Answer the questions while completing the tutorial. Pay attention to the dialogues!
|
||||
|
||||
## 1. What is the purpose of the 'compass heading' block?
|
||||
|
||||
Gets the compass heading of the BBC micro:bit in degrees
|
||||
|
||||
<br/>
|
||||
|
||||
## 2. Write the code that stores the compass heading into a local variable called 'degrees'.
|
||||
|
||||
<br/>
|
||||
|
||||
```
|
||||
let degrees = input.compassHeading()
|
||||
```
|
||||
|
||||
## 3. Write the 'If statement' that will check if the device is mostly pointing North. Display 'N' on the BBC micro:bit
|
||||
|
||||
<br />
|
||||
|
||||
```
|
||||
if (degrees < 45) {
|
||||
basic.showString("N", 150)
|
||||
}
|
||||
```
|
||||
|
||||
## 3. Write the 'If statement' that will check if the device is mostly pointing East. Display 'E' on the BBC micro:bit
|
||||
|
||||
<br />
|
||||
|
||||
```
|
||||
if (degrees < 135) {
|
||||
basic.showString("E", 150)
|
||||
}
|
||||
```
|
||||
|
||||
## 3. Write the 'If statement' that will check if the device is mostly pointing South. Display 'S' on the BBC micro:bit
|
||||
|
||||
<br />
|
||||
|
||||
```
|
||||
if (degrees < 225) {
|
||||
basic.showString("S", 150)
|
||||
}
|
||||
```
