-- ChiliPeppr Joystick controller
-- Used to control analog joysticks that are implemented just using
-- variable resistors where you feed in 3.3v and get out a variable voltage
-- based on position of the joystick. Joysticks like the Playstation portable
-- or Xbox joysticks work this way and are readily available on Amazon, Ebay,
-- or Aliexpress.
