LED Circuit

I am proud to offer this site to the robot and robotics enthusiasts, electronic engineeing students, embedded developers, and, generally to those who enjoy building and playing with geek toys, and fun, geeky, nerdy, novelty items. We all enjoy playing with high-tech toys and kits, and this page will help you toys enjoy those robot kits, embedded development systems, and novelty audio products with greater understanding.
