What am i doing wrong ? thanks

Do you get this error when you are importing the template? or in the second steps?

In the second steps , after I copy the updated code provided .

According to the error the device is not found, or the port is occupied, so maybe try:

  • to make sure the board is properly connected the led is on.
  • If the Arduino IDE is open, close it.
  • Give a quick double tap to the reset buttons on the board to set it in bootloader mode. This will "help" the port on the board accept a new program (after the quick double tap you will see the L led (orange one) fading in and out), then try to upload again.

Did you manage to solve the issue?
