Hello, I'm quite new to Arduinos and I recently bought a arduino pro mini w/ AtMega328. As I try to load up my code, I receive the error code "avrdude: stk500_getsync(): not in sync: resp=0x00". I have checked off the correct board, COM, I have updated drivers, and there are no pins connected to my RX. Green LED blinks in 1 second intervals and red LED has a constant light. I would appreciate any help.
