/* Demonstration sketch for combo analog and digital joystick
  PM Wiegand October 1 2025
	Widely available on Amazon – search analog joystick
	Connect VRX and VRY to analog input pins on microcontroller
	Connect SW to a digital input (INPUT_PULLUP) pin on microcontroller
	Output printed to Serial Monitor, can also visualize with Serial Plotter
