JOYSTICK TO ARDUINO

 

Joystick Control Using Arduino Uno

Learn how to interface a joystick module with Arduino Uno and read its X-axis, Y-axis, and push-button values. This simple 5-wire connection project is perfect for beginners in robotics, game controls, and remote control systems.

Joystick to Arduino Connection (5 Wires Only)

The joystick module has 5 pins:

Joystick Pin	Arduino Connection	Function
VRX	A0	X-axis analog input (0–1023)
VRY	A1	Y-axis analog input (0–1023)
SW	Pin 2	Push button (LOW when pressed)
+5V	5V	Power supply
GND	GND	Ground

That’s it — just five wires!

How the Joystick Works

Inside the joystick module:

• It contains two potentiometers

• Each potentiometer outputs a voltage between 0V to 5V

• Arduino converts this voltage into digital values from 0 to 1023

---

 Axis Behavior

• Center Position: Around 512

• Move Left: X value decreases (toward 0)

• Move Right: X value increases (toward 1023)

• Move Up: Y value increases

• Move Down: Y value decreases

---

 Button (SW Pin)

• When pressed → LOW

• When released → HIGH

• Works like a normal push button (internally connected to ground when pressed)

---

 Arduino Code Example

const int xPin = A0;
const int yPin = A1;
const int swPin = 2;

void setup() {
  Serial.begin(9600);
  pinMode(swPin, INPUT_PULLUP);
}

void loop() {
  int xValue = analogRead(xPin);
  int yValue = analogRead(yPin);
  int buttonState = digitalRead(swPin);

  Serial.print("X: ");
  Serial.print(xValue);
  Serial.print(" | Y: ");
  Serial.print(yValue);
  Serial.print(" | Button: ");
  Serial.println(buttonState == LOW ? "Pressed" : "Released");

  delay(200);
}

What This Code Does

• analogRead(A0) → Reads horizontal movement

• analogRead(A1) → Reads vertical movement

• digitalRead(2) → Detects button press

• Serial Monitor displays live joystick data
