How it works

A servo is a small motor. A 180 degree servo turns to an angle, so its arm waves. A 360 degree servo spins until you stop it. The micro:bit can measure light, so your code can move the arms when a torch shines.

The robot from the front, with a torch shining yellow rays onto the micro:bit's lights. Beside it, a dial's needle has climbed past a marked line, and red arrows show both arms swinging their pompoms up and down.
