Display the direction that the micro:bit is facing using the compass
### ~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!

## Step 1
2016-06-12 03:12:08 +02:00
Create a loop that will continuously update the reading of the compass.
2016-06-12 01:43:54 +02:00
```blocks
basic.forever(() => {
2016-06-12 03:12:08 +02:00
})
2016-06-12 01:43:54 +02:00
```
## Step 2
2016-06-12 03:12:08 +02:00
Store the reading of the micro:bit in a variable called `degrees`.
2016-06-12 01:43:54 +02:00
```blocks
basic.forever(() => {
2016-06-12 03:12:08 +02:00
let degrees = input.compassHeading()
})
```
## Step 3
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) {
2016-06-12 01:43:54 +02:00
basic.showString("N");
2016-06-12 03:12:08 +02:00
}
2016-06-12 01:43:54 +02:00
});
```
2016-06-12 03:12:08 +02:00
## Step 4
If `degrees` is less than 135, the micro:bit is mostly pointing East. Display `E` on the micro:bit.
2016-06-12 01:43:54 +02:00
```blocks
basic.forever(() => {
2016-06-12 03:12:08 +02:00
let degrees = input.compassHeading();
if (degrees < 45) {
2016-06-12 01:43:54 +02:00
basic.showString("N");
2016-06-12 03:12:08 +02:00
}
else if (degrees < 135) {
2016-06-12 01:43:54 +02:00
basic.showString("E");
2016-06-12 03:12:08 +02:00
}
2016-06-12 01:43:54 +02:00
});
```
2016-06-12 03:12:08 +02:00
## Step 5
If `degrees` is less than 225, the micro:bit is mostly pointing South. Display `S` on the micro:bit.
2016-06-12 01:43:54 +02:00
```blocks
basic.forever(() => {
2016-06-12 03:12:08 +02:00
let degrees = input.compassHeading();
if (degrees < 45) {
2016-06-12 01:43:54 +02:00
basic.showString("N");
2016-06-12 03:12:08 +02:00
}
else if (degrees < 135) {
2016-06-12 01:43:54 +02:00
basic.showString("E");
2016-06-12 03:12:08 +02:00
}
else if (degrees < 225) {
2016-06-12 01:43:54 +02:00
basic.showString("S");
}
});
```
2016-06-12 03:12:08 +02:00
## Step 6
2016-06-12 01:43:54 +02:00
2016-06-12 03:12:08 +02:00
If none of these conditions returned true, then the micro:bit must be pointing West. Display `W` on the micro:bit.
2016-06-12 01:43:54 +02:00
```blocks
basic.forever(() => {
2016-06-12 03:12:08 +02:00
let degrees = input.compassHeading();
if (degrees < 45) {
2016-06-12 01:43:54 +02:00
basic.showString("N");
2016-06-12 03:12:08 +02:00
}
else if (degrees < 135) {
2016-06-12 01:43:54 +02:00
basic.showString("E");
2016-06-12 03:12:08 +02:00
}
else if (degrees < 225) {
2016-06-12 01:43:54 +02:00
basic.showString("S");
2016-06-12 03:12:08 +02:00
}
else {
2016-06-12 01:43:54 +02:00
basic.showString("W");
}
});
2016-06-12 03:12:08 +02:00
```
