Hello, I make mistake and I uploaded bad program to arduino uno. In program I set digital pin 0(RX) and 1(TX) to output and now I cant upload any program to arduino. Is there any way to clear memory in which is located arduino program? I was trying holding arduino reset button and tried to upload blink program at same time but it didnt work.
In arduino IDE output I see this error message:
avrdude: stk500_getsync(): not in sync: resp=0x00
