Sim Shifter

A shifter for sim racing games that uses limit switches for gear detection

Why does this exist

I have been thinking of making a sim shifter for a few months now and have never gotten around to it, I love sim racing and drifting, but I only have the paddle shifters on my wheel, which suck for drifting, so I needed a shifter.

How to build

Wiring

Wire the microswitches to the pro micro like this
