1  Using Arduino / Installation & Troubleshooting / uno r3 not in sync error. on: November 14, 2012, 11:46:03 am
Hi, I have a Uno R3 and im getting this message when i try to upload the sketch.
"avrdude: stk500_getsync(): not in sync: resp=0x30"

And i can't see the Uno on my com port list, its showing up as a USB with a "!"

Any ideas ?
