ABOUT THE PROJECT

A company that designs holiday ornaments, specializing in Remote IR and Lighting Technology. I was the project manager for a team of eight students that developed a remote controlled lighting system that used Pulse Width Modulation to control a tristate colored LED. It used priority methods so that the most critical tasks would always be performed first, and could be controlled using an IR device such as a remote control. The assembly code was written onto a microprocessor, which was wired to a series of LEDs and servos to control the hat. It could sing and dance, and make over 177,000 different shades of colors.
