Whenever I upload a program, this error message shows up: avrdude: stk500_getsync(): not in sync: resp=0x00
It was working just yesterday. but when I tried to upload a program today, it didn't work. I am a newbie to arduino, so please help!
I am using an arduino uno r3.
It would help to know which board you are using but here's a quick tip. Make sure the board selected in tools/board matches the board you are using. The board selected will be displayed at the bottom right corner of the arduino IDE.
