Audi DTM Steering Wheel for SimRacing

Project main site: https://www.thingiverse.com/thing:4891321

This is remix of Formula B1 - (Sim racing) steering wheel for Thrustmaster T300 RS wheel base. With other wheel mount or quick-release, this wheel could be also used for another wheel base.

All buttons are connected to Arduino Nano with common ground. Arduino Nano is connected to wheel base via mini-Din 6 pin connector (SPI serial protocol), so no external power, drivers or USB connection to PC is needed.

More info about HW and Arduino code is here https://rr-m.org/blog/thrustmaster-t300rs-steering-wheel-arduino-emulator/
