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. Not counting the board, there is about $8 USD in parts per bug. I designed this

It used to be that the number of different microcontroller chips available to the hobbyist was pretty limited. You got to use whatever you could manage to buy from the mail-order chip dealer, and that narrowed down the choice to a small number of chips. But times have changed. Digikey lists over 16000 different line

The Swiss AVR Knife bundles a number of AVR programming projects together in a single convenient Altoids Gum Tin. Because of the flexibility afforded by microcontroller programming, it also provides a starting point for any number of projects based on LEDs and sound output. The SAK can contain as many programs as the 8K of
