Hi,
thanks for your reply. I tried what you have suggested. After changing my USB cable windows could recognise it. However the loopback doesn't work. I've tried the drivers and still no luck. When I try and load a sketch the tx rx leds do not light up. I'vew tried holding down the reset button till Binary sketch size: 1026 bytes (of a 30720 byte maximum)
pops up.
I think I put 9volts on input 0. Would this cook anything?
