Buggy is a programmable LED craft project using a homemade, single-sided, PCB board, and a programmable AVR Attiny44v microcontroller. Buggy has two bi-colored LED eyes and can sense visible and IR light and emit sounds using a piezo speaker. I designed this as a craft project for the younger kids at a family reunion. The kids were given an assembled and tested board, and allowed to decorate it with foam, pipe cleaners, and feathers using hot glue. It was a big hit, and the creations that ensued were fascinating. Link to YouTube video The real fun is getting two Buggies together. They emit and detect IR and so can "talk" with each other. There is plenty of memory left on the chip, and several unused inputs, and given my programming ability, lots of room for improvement. I hope others find this intriguing enough to try and improve on. Hats off to Alex Weber's programmable LED instructable (http://www.instructables.com/id/Programmable-LED/) which sparked my imagination!
