I have this error
avrdude: verification error, first mismatch at byte 0x0002
0x64 != 0x62
avrdude: verification error; content mismatch
Any idea to solve this error??
Not without your code to see what you have done.
What type of Arduino are you trying to program? Have you selected the correct board type in the Arduino IDE (Tools - Board menu)?
you check the microcontroller IC isnot destroy ; check the port and board of arduino.
