Playing Pong game can be fun for whole family. You don’t need high graphics and even sound. It practically takes no time to build it and start enjoying. James Bruce simply put it together by using Arduino, couple potentiometers for control and couple resistors for generating video signal.
Most of code has been reused including TV out library that takes care of combining video signal. The game code has bee taken from Lamonica. It just has been updated with latest TV Out library and modified to support two players. The code also has an audio output which hasn’t been tested. Build it and have fun.
