Remove any connections to pins 0 and 1. These pins are used for communication with your computer, including uploads. Connecting anything to these pins can interfere with uploads.

Make sure you have selected the port of your Arduino board from the Tools > Port menu.

Sometimes the port will be labeled with the board name in the menu. Other times it will not. If you don’t know which port is your Arduino, you can find it like this:

  • Unplug your Arduino board from the computer.
  • Tools > Port
  • Note the ports, if any, listed in the menu.
  • Close the Tools menu
  • Plug your Arduino board into the computer.
  • Tools > Port - The new port listed in the menu is your Arduino board.

If the Tools > Port menu is grayed or the port of your Arduino does not appear on the menu:

  • Make sure your USB cable is fully inserted into the Arduino board and the computer.
  • You may need to install the driver for the USB-serial chip on your Arduino.
  • You may be using a charge-only or defective USB cable. Try a different cable or test your cable on another device to confirm that it works for data.
  • If you have a board with native USB (e.g. Leonardo, Micro, MKR), see TODO: add link to instructions for reset during upload fix
  • Some Arduino boards are shipped with their pins pressed into a black anti-static foam. This foam is conductive and so you must remove it before using your board.
  • Using a USB 3.0 port on your computer may cause problems. Try a USB 2.0 port.
