I did this project having Elegoo’s 12x12mm Square Buttons and WINGONEER PS2 Joystick controller plus Arduino Leonardo clone (pro micro) and joystick library” The JoypadOS project is a ...

This number sends a pulse to the Arduino, which in turn tells the servos how far to move. A joystick typically has have pins: VRx (the x-axis signal), VRy (the y-axis signal), SW (a pushbutton we ...

Guts from an optical mouse detect the motion. This is processed by an Arduino board which then uses a digital potentiometer to mimic the joystick movements on a PS2 controller.
