# Rotation
|
|
|
|
Find how much the micro:bit is tilted in different directions.
|
|
|
|
```sig
|
|
input.rotation(Rotation.Roll);
|
|
```
|
|
|
|
## ~hint
|
|
|
|
The BBC micro:bit has a part called the **accelerometer** that can
|
|
check how the micro:bit is moving.
|
|
|
|
## ~
|
|
|
|
### Parameters
|
|
|
|
* which direction you are checking: `Rotation.Pitch` (up and down) or `Rotation.Roll` (left and right)
|
|
|
|
### Returns
|
|
|
|
* a [number](/reference/types/number) that means how much the microbit is tilted in the direction you say, from `0` to `360` degrees
|
|
|
|
### Example: micro:bit leveler
|
|
|
|
This program helps you move the BBC micro:bit until it is level. When
|
|
it is level, the micro:bit shows a smiley.
|
|
|
|
If you are running this program in a browser, you can tilt the
|
|
micro:bit with your mouse.
|
|
|
|
|
|
```blocks
|
|
let pitch = 0;
|
|
basic.forever(() => {
|
|
pitch = input.rotation(Rotation.Pitch);
|
|
let roll = input.rotation(Rotation.Roll);
|
|
if (Math.abs(pitch) < 10 && Math.abs(roll) < 10) {
|
|
basic.showLeds(`
|
|
. # . # .
|
|
. . . . .
|
|
. . . . .
|
|
# . . . #
|
|
. # # # .
|
|
`);
|
|
} else {
|
|
basic.showLeds(`
|
|
# . . . #
|
|
. # . # .
|
|
. . # . .
|
|
. # . # .
|
|
# . . . #
|
|
`);
|
|
}
|
|
});
|
|
```
