Hi,
I've been loading a few test programs on my Arduino Uno, today I uploaded the blink program to test a pulsing output but now it won't stop or let me upload any more programs/sketches. When I try, I get the error below. I know this error is to do with ports but I've changed ports/coms but says the port is busy.avrdude: stk500_getsync(): not in sync: resp=0x00
I've tried everything, changing ports, rebooting etc but it just won't let me run any more sketches. Just blinks away every time I reconnect it. Has anyone else have this problem? I'm using windows 7. Thanks.
