Two-Component H-shifter for Racing Sims

What happened

A joystick like those found inside many game controllers is paired with an Arduino Pro Micro, with a very straightforward wiring configuration between them. From there it’s as simple as uploading some readily-available firmware, which [Jason] also demonstrates, and which has many options for various configurations of shifters.

But it can also be a fairly affordable hobby as well, with entry-level components being within reach for many. The two components only cover the electronics for the build, but this gets almost everything needed for the shifter squared away. These components are paired with a prototype 3D printed case and shift knob which provides the H pattern of choice.
