乒乓球，投射在墙上的一个Arduino控制激光

An Arduino controls a self-made laser projector that uses a laser, mirrors, and stepper motors. I programmed the Arduino to have the projector display a clock or play Pong. The code is licensed under the MIT license, so feel free to use it in your project. If it"s a commercial project, go right ahead - just let me know at alvin dot armea at gmail. More on the hardware later. Credits: All hardware including etching the PCB (except the Arduino) and code (except the clock sync program) by Albert Armea. PCB design by Mr. Anderes. Video demonstration at http://www.youtube.com/watch?v=TQWjmvKusxU .
