The chances of anything coming from Mars are pretty high if you’re watching a sci-fi B-Movie.

We’ll be bringing our menace from outer space with a servo motor. It’ll allow your actors to move and is a super simple (but still super flashy) way of exploring the world of robotics.

What you’ll need:

• A micro:bit, battery pack and micro USB cable, plus a suitable computer for programming.
• 1 small servo motor (eg a SG90 3,3v servo)
• 3 crocodile clip leads.
• 3 breadboard jumper wires.
