Not a question, per se....more of a show-n-tell, I suppose. Do you guys have a forum group for that? Or somewhere else to post these types of things? I didn't see it.

Ring — I hooked it up to my UNO, along with the Accelerometer/Magnetometer breakout board. I wrote a simple little sketch and...viola! An RGB LED compass
on my Arduino.
A quick little video I made of it --http://youtu.be/z4y-KiBOJ24
