I have two arduino UNO board, but I rarely use those two, only one. Today, I needed to use the one that was stored and it is not uploading the code. The load takes about one or two minutes and gives an error: stk500_getsync() attempt 10 of 10: not in sync: resp=0x02
where this "resp" value changes everytime i try to load.
I noted to that when I try to send something with Serial, the RX led does't blink.
My other Arduino is working perfect.
Help me please ;-;
