We decided to create a circuit that would activate a toy whenever someone logged into Roth Mobot's web site. We designed a simple system using an Arduiino, a home made Vactrol, a common electronic toy, and three simple scripts written in three programming languages We'd like to thank Chicago's Factory Smoke for his Vactrol suggestion, which stopped us from creating overly-complicated custom circuitry with transistors and diodes, and made the programming a piece of cake, resulting in an elegant circuit that electrically insulates the toy from the Arduino and the computer, and instead "optically couples" them with light.
