What is a Junkbot?
Stage 2 - Physical arrangement of Microbit and motor control board
The control part is this via a Micro:bit (http://www.bbc.co.uk/programmes/articles/4hVG2Br1W1LKCmw8nSm9WnQ/the-bbc-micro-bit). Kitronik produce a motor driver board, and provide quite a bit of support for it, for the Micro:Bit (the latest version of the board can be found at https://www.kitronik.co.uk/5620-motor-driver-board-for-the-bbc-microbit-v2.html ). A 6v battery pack is connected (see on the left of the image) and wires going to a motor are attached to the first block on the front left (marked as motor A).
Stage 3 - Built Junkbot
Now we just need to put them together by taping (or fixing somehow) the motor to the junkbot built in stage 1. A further possibility is to attach the Micro:Bit, motor driver board and battery pack to the junkbots; but this adds weight.
Stage 4 Code
Using Micropython via the online editor https://www.microbit.co.uk to program the board and therefore the junkbot.
