Hotas Throttle

Custom hotas for playing Flight Simulator games.
Although the project is still in progress, it is fully functional. In fact, I'm already playing Squadrons with it.

I used for sliding movement a linear rail from an old 3d Printer 8mm.

For the electronics I used an Arduino Leonardo ATmega32U4 (https://www.amazon.es/gp/product/B07MY2VZX9/ref=ppx_yo_dt_b_asin_title_o06_s00?ie=UTF8&psc=1) using this library: https://github.com/MHeironimus/ArduinoJoystickLibrary

In total the hotas needs 4 potentiometers, 11 pull up buttons and joystick module for thumb.
