Rotation

Find how much the @boardname@ is tilted in different directions.

input.rotation(Rotation.Roll);

~hint

The @boardname@ has a part called the accelerometer that can check how the @boardname@ is moving.

~

Parameters

kind means which direction you are checking: Rotation.Pitch (up and down) or Rotation.Roll (left and right)

Returns

a number that means how much the microbit is tilted in the direction you say; for Rotation.Pitch from -90 to 90 degrees and for Rotation.Roll from -180 to 180 degrees.

Example: @boardname@ leveler

This program helps you move the @boardname@ until it is level. When it is level, the @boardname@ shows a smiley.

If you are running this program in a browser, you can tilt the @boardname@ 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) {
        basic.showLeds(`
            . # . # .
            . . . . .
            . . . . .
            # . . . #
            . # # # .
            `);
    } else {
        basic.showLeds(`
            # . . . #
            . # . # .
            . . # . .
            . # . # .
            # . . . #
            `);
        }
	});
