Python script to control the volume of the original arcade1up cabinets.
Script was written in 2018 for the original Street Fighet II Arcade1Up cabinet.
After removing the original board, I connected the wires from the original volume control switch to the GPIO pins on the Raspberry Pi.
The switch position corresponds to a button press and sets the volume level accordingly.
Set the script to run on startup.
You can use any valid pinout configuration, I used 16, 20, and 21.
