Since I'm getting the problem sometimes (so not all the time) that the software cannot upload to the arduino board giving the:
stk500_recv(): programmer is not responding avrdude:
nothing works then such as reset, unplug and wait a minute, restart the computer etc... but when I unplug the wire to the ground pin... EUREKA... it's working again. I got a few LEd displays and a few buttons connected to ground (even split it up over the other ground pins, but I guess they are all connected internally...
so the big question is:
Is it possible to connect to much connections to the ground pin(s)??
or am I missing something else
