I don't see an error. Looks like you only compiled and did not try to upload.

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

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.
