Thread: Arduino upload problem

    Default Arduino upload problem

    Hello Guys,

    While working on the motor control project using Arduino and L293d, I by mistake applied 12v to the 5v Vin pin of arduino. And now when I am trying to upload code to the arduino it give me error ‘avrdude: stk500_getsync(): not in sync: resp=0x30’.

    Have I damaged my arduino? Or it possible to make it alive again?

    Please let me know what I can do.

    I also made a mistake connecting the ttl gps inputs to arduino this way and burnt the Micro-controller. I replaced the controller with a new one now it works fine. I also got the same error after burning it.
