Make an Xbox 360 controller with an Arduino Uno I was thinking of making a custom Xbox 360 controller (racing wheel) with the Arduino Uno plugged into the Xbox. How would I emulate the buttons/triggers on the original controller with the Arduino? Is there a library that can help me do this?
Arduino Uno's do not have a native USB Connection. However, if you use an Arduino Leonardo or Pro Micro, you can use MHeironimus's Joystick library, However I am not sure if they are specifically compatible with the XBox.
