Shake

You can find when someone is shaking the BBC micro:bit by checking its accelerometer (it finds whether the micro:bit is speeding up or slowing down).

Unscramble these blocks in the editor to show a frownie when someone shakes the micro:bit. (Ouch!)

input.onGesture(Gesture.Shake, () => {
    basic.showLeds(`
. . . . .
. # . # .
. . . . .
. # # # .
# . . . #`);
});
