Can't upload new sketch Recently I have unsoldered most connector pins there are on the arduino uno board.
However, when I now attempt to upload a new sketch (works when I upload it to another model) it gives me the following error:

&gt; avrdude: stk500_recv(): programmer is not responding

I would like you take a look at my arduino board to see whether I have unsoldered important pins which might have to be connected.

Also when I try to upload a new sketch the 'L'-LED doesn't flash but the RX one.

(BTW: Yes I've set the settings to the correct board, port etc...)



Thanks for any solution attempts!
Pin 0(RX) and 1(TX) and the RESET pins are important to upload a sketch. Can you check those carefully with a magnifier ? Perhaps there is some solder that shortcuts to something else, or perhaps you damaged a copper trace.
