Step 6: Select your serial port
Select the serial device of the board from the Tools | Serial Port menu. This is likely to
be COM3 or higher (COM1 andCOM2 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 board. Reconnect the board and select that serial port.
Step 7: Upload the program
Now, simply click the "Upload" button in the environment. Wait a few seconds - you
should see the RX and TX leds on the board flashing. If the upload is successful, the
message "Done uploading." will appear in the status bar.
