I was also able to use my Arduino to program an ATtiny85 microcontroller (which costs significantly less than the micro-controller sticker) to make an LED blink and fade.
I used the resources at Nexmap.org and Highlowtech.org to pull this off. It took me a few tries (and some cable wiggling), but it finally works!
They suggest using an AVR Tiny Programmer to make the programming easier. One of the benefits of using the tiny programmer is that you can put an adapter on it (provided with the Circuit Sticker sensor pack), allowing you to quickly go between programming the sticker or an ATtiny85 without much fiddling.
In the photo to the left, I haven't soldered yet.
Stay tuned to see where this latest diversion takes me, or visit my other blog, Bling the Book.
