Select your board type and port
You'll need to select the entry in the
Tools > Board
menu that corresponds to your Arduino or Genuino board.
Select the serial device of the board from the Tools | Serial Port menu. This is likely to be
COM3
or higher
(
COM1
and
COM2
are usually reserved for hardware serial ports). To find out, you can disconnect your board
and re-open the menu; the entry that disappears should be the Arduino or Genuino board. Reconnect the
board and select that serial port.
