avrdude: stk500_getsync(): not in sync: resp=0x00
What must I do to get round this response? I've done everything according to the Youtube video by Morton Lowton, but when I get to upload it, this message appears, and when going into system monitor - no output, which I guess is due to the above message.
What's the issue, how do I solve it. The port I'm using is port 4, as far as I can tell - all help gratefully devoured!
