jmagnus:
Speaking of working. I found out I had fried my arduino uno. I didnt realize I needed a voltage regulator if I wanted to power it via the usb port.Do you mean you were supplying more than 5V through the USB port? Yes, that wouldn't do it any good.
That is exactly what I was doing. I figured the Arduino had a built in regulator for usb power(that would be redundant)... ID10T error!
In other news I got the device to work using the following code.
Thanks for everyones input and help!
