Steering wheel and pedals For FH5

Dear, I'm just a clumsy amateur.
Here are the pedals, the body, and the steering wheel.
What's what-
I made 3 pedals (note that the body doesn't fit together)
The pedals are powered by Hall sensors (I just glued them together).
The steering wheel was based on a potentiometer and a 609 bearing.
I made it using the ARD NANO V3.
If you want to build this terrible thing, please contact me and I'll help. I can also provide the source code.
