Sim Steering Wheel

The Sim Steering Wheel is probably the most patience-testing thing I have ever made. When one thing worked, another wouldn't. This project single-handedly fried 4 Arduino nanos. It uses a 4in Raspberry Pi monitor in the center to show important data, such as the gear you're in and speed. It is vaguely based off the wheel used in the Mercedes W11, one of my favorite race cars. It has 12 buttons, 3 encoders, and 3 paddles. It uses 3 parts off Thingiverse: the paddles, the paddle mount, and the hub mount, as I use custom one on the wheel base from Thingiverse, which allows for quicker wheel switching, as well as moving the wheel closer to me, which has made it more ergonomic. The wheel requires the use of SimHub to receive and send data, as well as to display something on the display, as it just acts as another monitor. It is possible to replace it with something USBD480 or a VOCORE display, which would also reduce the amount of cables down to a single USB cable, but I wasn't able to get my hands on either one, so a normal display had to do. The center encoder currently changes what is displayed, but that can easily be changed in SimHub. There is also an led strip above the display, which is used for RPM, flags, and DRS status.
