Arduino Example Code
The example code can be found in the following GitHub repository. The example includes the original host keyboard code from Arduino. The code was modified to work with a 20x4 SerLCD and eventually the 16x2. To save power and the screen, the code was further modified to be used with the Qwiic PIR motion sensor in order to toggle the RGB LED and screen. For the scope of this project tutorial, we will be using examples 1b and 2.
