My computer doesn't recognize the Arduino board


If your computer doesn’t recognize the Arduino board, first try the following:

  • Disconnect and reconnect the USB cable.
  • Replace the USB cable
  • Change the usb port (here is how to do that).
  • Change the computer
  • Start the arduino without atmega 328p (?)
  • Restart atmega 16uf in DFU mode

If none of the above work, it is possible that your Arduino board is broken.
