-* What is this?
-This is a simple recipe for turning your Arduino into a usable
-joystick/gamepad.
-
-I am using [[https://robotdyn.com/joystick-shield-for-arduino.html][RobotDyn Joystick shield]] which makes the whole process
-trivial.
-
-* Compiling
-Install the dependencies:
-- [[https://github.com/sudar/Arduino-Makefile][Arduino Makefile]] (available as arduino-mk in Ubuntu/Debiab)
-- [[https://github.com/MHeironimus/ArduinoJoystickLibrary][Arduino Joystick Library]]
-
-Then just run ~make~ and ~make upload~ to flash the board.
-
-* Wiring
-There is nothing to wire -- just pop the shield onto your board and
-plug it in!
