Re: Selecting a microcontroller
I would definitely recommend one of the Arduino models. I just got one a couple of weeks ago and it is great. The programming is easy, the software runs great on the Mac (I even got it up and running with XCode, you can PM me for the template), and it could be used in future projects. There is even the Arduino LilyPad, a board designed for clothing applications. It sounds like it would be perfect for what you need.
Also, each output pin can provide 40ma, twice your requirement. The chip can be found for about $7. The full-sized arduino boards are socketed so you could replace the chip if needed.
Even if you don't go for the arduino, I would definitely recommend the Atmega168 chip because it is cheap, durable, and can be programmed on almost any OS using widely available open-source tools.
