What is this?
This is a simple recipe for turning your Arduino into a usable joystick/gamepad.
I am using RobotDyn Joystick shield which makes the whole process trivial.
Compiling
Install the dependencies:
- Arduino Makefile (available as arduino-mk in Ubuntu/Debiab)
- Arduino Joystick Library
Tweak joystick.ino to suit your needs. In particular, enable or
disable using the Y axis as additional buttons.
Then just run make and make upload to flash the board.
Y axis as buttons
Using the Y axis on the joystick as additional buttons is useful for playing e.g. SuperTuxKart, where you only need the joystick for steering.
Wiring
There is nothing to wire – just pop the shield onto your board and plug it in!
Debugging
You can use the jstest tool on Linux.
