Snake lamp is a prior project to the Cubik. I tried to implement the well-known Nokia Snake game to the traditional desk lamp.
This project uses one Arduino Uno to control 25 LEDs. The controller only has 4 buttons to control the direction of the Snake. The switch button on the left hand side serves as a changing-mode from a traditional on and off lamp to game setting. Please check out the link below to see the product in action.
