simple Arduino Joystick to Unity via Joystick.h

Arduino joystick code

#include <Arduino.h>

#include "Joystick.h" // use this library to be a joystick

// Create Joystick
Joystick_ Joystick;

// -----------------------

// This sketch shows the basic operation of the Thumb Joystick (COM-09032) and breakout board (BOB-09110).
// The joystick outputs two analog voltages (VERT and HORIZ), and one digital signal (SEL) for the pushbutton.
 
const int VERT = 0; // analog
const int HORIZ = 1; // analog
const int SEL = 2; // digital
 
//initialize variables for analog and digital values
int vertical, horizontal, select;

void setup(){
 
// make the SEL pin an input
  pinMode(SEL, INPUT_PULLUP);

  // set up serial port for output
  //Serial.begin(9600);
}

void loop(){

  // read all values from the joystick
  vertical = analogRead(VERT); // will be 0-1023
  horizontal = analogRead(HORIZ); // will be 0-1023
  select = digitalRead(SEL); // will be HIGH (1) if not pressed, and LOW (0) if pressed

  //put new joystick data to joystick objrect and send
    Joystick.setXAxis(vertical);
    Joystick.setYAxis(horizontal);
     
    Joystick.setButton(3,select-1);
    Joystick.sendState();

  delay(10);

  return;

    // print out the values
  Serial.print("vertical: ");
  Serial.print(vertical, DEC);
  Serial.print(" horizontal: ");
