Halloween is only a few days away. We're getting into the spirit by building a remote control color changing pumpkin. Channel buttons 0-8 on the remote toggle the colors of the rainbow. Button 9 activates an 'angry pumpkin' mode that flashes a scary red strobe for a few seconds.
It uses a minimal PIC 18F2550 circuit that decodes the remote control signals and drives a ShiftBrite color changing LED module. The F2550 is a USB PIC with a USB bootloader, so it's technically a USB upgradable pumpkin too.
