You may want to move to a MOSFET instead of a TIP-120. Runs alot cooler. Check out: http://sensitiveresearch.com/elec/DoNotTIP/index.html
Works great. I just bought a 5 pack of these from Amazon for a song. I followed your instructions and it works great. One question though, you changed a few things in the code (specifically the delayMicroseconds(1000)) and added much lower delay values elsewhere. Why these changes? What did you fix with these changes?
I had a little trouble only because I didn't know that my breadboard was divided into 4 sections so that there was no connection between the power on the left side of the breadboard and the right. Once I move the power leads to the correct quadrant, the light flashed like a charm. Thanks for the instructable!
