Optical USB Mouse Connected to Arduino
I was trying to figure out if a usb optical mouse could be used as a motion sensor with an Arduino microcontroller board. It turns out it can. I did some google searching and found the exact answer to my question. This paper by Martijn Jansen pretty much explains exactly what to do.
Update: He also has a site with source code/library on how to interface with an optical mouse. It is here.
Now I just have to recieve my Arduino board…
