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

This Instructable will walk you through the steps needed to make a stained glass pendant with anLED that blinks in a pattern using a microcontroller. The blink pattern is an actual firefly song of a type of Japanese firefly. It is a scaled down version of the Jar of Fireflies code that my partner wrote.

Introduction Ever fancied building your own camera controller? IMPORTANT NOTE: Capacitors for the MAX619 are 470n or 0.47u. The schematic is correct, but the component list was wrong – updated. This is an entry into the Digital Days competition so if you find it useful, please rate/vote/comment favourably! If you reallly like it and are a stumbler,
You know it, in the winter time it is hard to get up, because it is dark outside and your body just won’t wake up in the middle of the night. So you can buy an alarm-clock that wakes you up with light. These devices are not as expensive as few years ago, but most
