Thanks Steve. We're preparing to use the Iris for a middle school technology class in a few months, and I wanted to make sure I could explain how all the parts worked. I'll try the Arduino forum.
For those that want to learn, here are links to all the other electronic parts inside the Iris.
I don't know if you have already seen this or not. A while back, someone posted this article here:
You found it! Thanks Ken!
Next on my wish list is a place to buy them.
Ah ha! Thank you!
I was told that spare parts for everything on the IRIS will be available at some point in the future.
