This is a simple way to make an Arduino compatible circuit on a breadboard. The only additional components needed are a 0.1µF capacitor and a 1k resistor. This is amazingly simple. I have to try this out for myself.
Here is a recipe for using the atmega168 as a standalone arduino. It uses the internal oscillator of the arduino running at 8mhz, and is powered at 3.3 volts. I used this together with a xbee radio modem for my wind-up birds project.
