 On a PC you can use the command line and the following command:
 
 ```
+chgport
+```
+
+On my PC when I use the `chgport` command I get the following output:
 
 ```
+AUX = \DosDevices\COM1
+COM1 = \Device\Serial0
+COM3 = \Device\Serial2
+```
+
+In my Node.js I would use `COM3` as my serialport string.
+
+If you're not sure which one is your Arduino, just disconnet your Arduino and execute the cpommand again and take note of which port is no longer on the list. 
 
 Or you can find the name in [Arduino Create](https://create.arduino.cc/editor) in the drop down menu used to select your Arduino.
