This is a fully operational candy vending machine that uses Arduino, touch sensors, and conductive ink to make a hand-drawn foam board interactive.
I had a lot of fun with this project as I made almost every part of it from scratch. I cut and glued the wooden housing for the parts, curled the springs from wire, and laser-cut the coin accepter. I also rewired the Servo motors to make the coding easier, since I had accidentally bought a continuous rotation motor instead of a 360 one.
