Hello all,
Using the sparkfun red board programmed with arduino.
looking at the portb pin5 on the 10 pin connector (with an oscope) I see a AC signal about 3 volts pk to pk.
I would not think it should be there. I am powering from the usb adapter on the board to my pc.
Please let me know if that is normal or not.
Thanks
