Programming Circuit Sticker and ATtiny85 Microcontrollers

Recently, I started playing around with a programmable micro-controller sticker, available from Chibitronics. Using the resources at Chibitronics.com, I was able to use my Arduino Uno as a programmer to change the code on the sticker!  It was almost as fun as programming a LilyPad Arduino in an e-textile, only this time I got to use my favorite medium, paper!  I'm still just playing around at this point, but I am eager to learn more.

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.

I am excited about the possibilities for using these both in a bookbinding project or an illuminated writing activity!

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.
