Joystick Module (XY + SW)

The Joystick Module is an analog input device similar to the joysticks found in gaming controllers. It provides analog outputs for X and Y axes and a digital output for the built-in push button, making it perfect for controlling robotic movements, servo angles, or as a user input device.

How It Works?

The joystick uses two potentiometers to detect movement along the X and Y axes. As you move the stick, the output voltage changes from 0V to 5V, which can be read by a microcontroller’s analog pins. Pressing the joystick triggers a digital LOW signal on the SW pin.

Key Features

Analog X and Y axis output
Digital push button output (SW)
Operating voltage: 5V
Durable design with smooth motion
Ideal for Arduino and ESP32


// Joystick Module Example with Arduino
// Connections:
// VCC → 5V
// GND → GND
// VRX → A0
// VRY → A1
// SW  → D2

const int xPin = A0;  // X axis
const int yPin = A1;  // Y axis
const int swPin = 2;  // Push button

void setup() {
  Serial.begin(9600);
  pinMode(swPin, INPUT_PULLUP);
  Serial.println("Joystick Ready!");
}

void loop() {
  int xVal = analogRead(xPin);
  int yVal = analogRead(yPin);
  int swVal = digitalRead(swPin);

  Serial.print("X: ");
  Serial.print(xVal);
  Serial.print(" | Y: ");
  Serial.print(yVal);
  Serial.print(" | Button: ");
  Serial.println(swVal == LOW ? "Pressed" : "Released");

  delay(200);
}
