This project connects a Hori Mario Kart Racing Wheel to an Xbox Adaptive Controller. The Kart wheel controls the XAC left joystick X axis. The Kart dpad controls the XAC dpad. The gas and brake are controlled by variable triggers plugged into the XAC RT/LT jacks. This allows drivers who are not able to use foot pedals to join the fun. Most of the Kart buttons map to XAC buttons. The Xbox Accessory app can remap the buttons as desired.
The second reason for this project is to watch reactions to a Mario Kart wheel on an Xbox One console.
Note: The project does not make the Mario Kart game run on Xbox.
Other wheels probably will not work but the Arduino souce code is included. There is a Mario Kart Mini Racing Wheel but it may not work the same. I doubt expensive Logitech, Thrustmaster, etc. racing wheels work with this project.
The Kart gas and brake foot pedals are not supported because the XAC USB interface does not pass trigger values. The "Logitech G Adaptive Gaming Kit for the Xbox Adaptive Controller" includes two variable triggers. Plug these into the XAC RT and LT jacks to control gas and brake. If you are handy with crafting, mount the triggers to the wheel so the driver can keep both hands on the wheel while controlling gas and brake.

The uf2 directory contains the firmware for the Adafruit board. Put the Adafruit in bootload mode using the two buttons as described here When the Flash drive named RPI-RP2 appears, drag and drop the uf2 file on the drive. Wait a few seconds for the firmware update to finish. The RPI-RP2 will disappear. The board is ready to be plugged into the XAC.
If you change the source code, it can rebuilt using the Arduino IDE or compatible development system.
