An analog joystick has the followin two dimensions(x and y axis) and state that is set when joystick is pressed

Components Required

  • Arduino uno
  • Arduino Mega 2560(any board you have can work. This tutorial will used Arduino Mega 2560)
  • KY-023 Joystick.
  • 2 jumper wired

pins

KY-023 has 5 pins

  • GND - Ground Pin
  • +5V (5V pin)
  • VRX(X-axis voltage)
  • VRY(Y-axis voltage)
  • SW (correponds to pressing down the middle joystick button)

Procedure

  1. Set up your connection as shown in the followinf image.

joy stick connecting image

  1. Connect ground pin to ground

  2. Connect 5v pin to arduino 5v

  3. Connect VRX to ‘A0’

  4. Connect VRY to “A1”

  5. SW pin is connected to pin ‘2’

const int inX = A0; // analog input for x-axis
const int inY = A1; // analog input for y-axis
const int inPressed = 2; // input for detecting whether the joystick/button is pressed

int xValue = 0; // variable to store x value
int yValue = 0; // variable to store y value
int notPressed = 0; // variable to store the button's state => 1 if not pressed

  pinMode(inX, INPUT); // setup x input
  pinMode(inY, INPUT); // setup y input
  pinMode(inPressed, INPUT_PULLUP); // we use a pullup-resistor for the button functionality
  
  Serial.begin(9600); // Setup serial connection for print out to console

  // print out values
  Serial.print("X: ");
  Serial.println(xValue);
  Serial.print("Y: ");
  Serial.println(yValue);
  Serial.print("Not pressed: ");
  Serial.println(notPressed);
  
  // The following delay of 1000ms is only for debugging reasons (it's easier to follow the values on the serial monitor)
  delay(1000); // Probably not needed for most applications
