Run the Processing sketch
If the processing sketch does not work, you may need to modify the following line:
myPort = new Serial(this, Serial.list()[2], 9600);
You may need to change the parameter inside Serial.list()[N]. A List of available COM ports will
appear in the lower portion of the sketch window. Remember that COM port selection begins at 0.
Typically your Arduino will appear as the highest COM number if it is the only device connected to
your computer.
The Arduino shows up as COM38. This is found in the Serial List at array element “2”.
