Oh and 2 more thing's
First, you will have to reset the shield every time you copy your code to the Arduino, by pressing the little reset button on the CuHead shield...
Second, it's a interesting fact for advance user. If you Input Pull-up Pin9, if you haven't remove the led Jumper, you can write a routine that will detect that the CuHead has not been connected for some time and reconnect, That would be good if you UNO is hooked on battery but not you internet sharing box, and let say maybe the sector goes down, when electricity come back you Arduino reconnect.
Since the red LED mean's connected, I found other utility that I wont talk about here, but any way. Have fun.
Yep that's pretty mutch what I had to say about the CuHead so far. Cool board and not to expensive.
