Here’s the finished, working ToyBot. ToyBot is made from a cheap RC toy car. I took out the radio electronics and put in an Arduino microcontroller and an Adafruit Motor Shield motor controller and some sensors. ToyBot drives around the floor looking for light (or for shade, if it’s too hot). When it finds a good spot it stops and goes to sleep. It wakes up when the light or temperature changes, and resumes driving.
