# compass challenges
Display the direction that the micro:bit is facing using the compass
## Before we get started
Complete the following [guided tutorial](/lessons/compass/activity), your code should look like this:
```blocks
let degrees = 0;
basic.forever(() => {
degrees = input.compassHeading();
if (degrees < 45) {
basic.showString("N");
}
else if (degrees < 135) {
basic.showString("E");
}
else if (degrees < 225) {
basic.showString("S");
}
else {
basic.showString("W");
}
});
```
### Challenge 1
Instead of displaying `N` when the BBC micro:bit is pointing North, display a star to indicate the north star.
```blocks
let degrees = 0;
basic.forever(() => {
degrees = input.compassHeading();
if (degrees < 45) {
basic.showLeds(`
# . # . #
. # # # .
# # # # #
. # # # .
# . # . #`);
}
else if (degrees < 135) {
basic.showString("E");
}
else if (degrees < 225) {
basic.showString("S");
}
else {
basic.showString("W");
}
});
```
* 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.
```blocks
let degrees = 0;
basic.forever(() => {
degrees = input.compassHeading();
if (degrees < 45) {
basic.showString("NORTH");
}
else if (degrees < 135) {
basic.showString("EAST");
}
else if (degrees < 225) {
basic.showString("SOUTH");
}
else {
basic.showString("WEST");
}
});
```
* Run your code to see if it works as expected
### Challenge 3
Display your own unique message for each direction.
