A 3-D CIRCUIT

摘要

For my last project in this series, I wanted to make something simple, fun, and constructed one hundred percent from RadioShack parts. I came up with an LED desk toy that controls a set of RGB LEDs that change the colors based on the toy's physical orientation. Right now, I have it programmed as an egg timer. If I put it down on one side, the LEDs light up in red and blink after 15 minutes.
