There are a TON of pages out there on how to solve this error. The problem is none of them worked for me. The typical solutions range from not having the correct serial port or correct Arduino model board selected under the Tools menu in the Arduino software, to not having a driver (or the correct driver) loaded.
However, the frustating part for me is I KNEW I had the correct serial port and board and driver selected.
When I use easyVR shield my arduino have this error “avrdude: stk500_getsync(): not in sync: resp=0x00” but without easyVR shield dont have this error … operate normally. HELP!!!
