Flight Simulator Trim Wheel

Here's a elevator trim controller for your flight simulator. I use it with FS2020 but it should also work with other flight simulators, as it is recognized in Windows (10 or 11) as a joystick type device.
I wanted a robust trim wheel that fits on the Saitek throttle quadrant and also a system that preserves the axis of the encoder. The axis of the wheel and the encoder are connected by gears (ratio 1/1).

This trim wheel requires an arduino micro pro or an arduino leonardo (or another compatible brand like the one I used) only compatibility with the Joystick library .
I provide the code for a trim wheel configured as 2 buttons, + and -, (as on the saitek yoke) and not as a potentiometer with a MAX/Min range: this makes it easy to be compatible with the autopilot (at least for FS2020).

I also provide the Fusion 360 file to adapt this trim to your needs.
