Euro truck Simulator Keycaps

Inspired by the 12 Button macro keyboard I modified the model for Euro truck simulator. I made 12+1 keycaps for euro truck simulator. And I rewrote the code for the Arduino so that the keypad is now recognized as a game controller so that there are no more conflicts with double key combinations.
 

At the bottom of the code you can adjust which button is linked to which input. This way there is no mandatory soldering order.

//  inspired by Stuart Brand (JamHamster)https://github.com/jamhamster
//  Inspired by Matthey Heironimus test sketch JoystickButton
//  13/10/2024 WAB
//  For Arduino Leonardo and Arduino Micro only.
//  Based with thanks on the Gamepad Example code by Matthew Heironimus (https://github.com/MHeironimus)
//  Uses the excellent Joystick library here: https://github.com/MHeironimus/ArduinoJoystickLibrary
