John Graham-Cumming has used an Arduino-compatible board, simple circuitry, and two metal cans to create a simple games console that plays Pong. Programming for Arduino video out is simple using the tvout library, and the code for many games is freely available around the Internet. Here is a short demonstration of the Cansole at play:
It just goes to show once again what you can do with Arduino and some imagination. To get started with your own Arduino-embedded projects, use the Freetronics LeoStick - one of the smallest a on the market with full USB interface, a piezo and onboard RGB LED:
