Rotation
Find how much the micro:bit is tilted in different directions.
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
kindmeans which direction you are checking:Rotation.Pitch(up and down) orRotation.Roll(left and right)
Returns
- a number that means how much the microbit is tilted in the direction you say, from
0to360degrees
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.
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) {
