I've built a maze traversing car with an arduino. The maze was just black lines on a large white sheet. The code was fairly straightforward (Depth First Search), but this was my first time working with hardware. The car used a row of LDRs to know its location relative to the lines of the maze which was the main source of issues. After countless rebuilds of the car and tweaks in the code we finally got the car to work which was an extremely gratifying moment.
