XY Two-Axis Joystick Module

Description

XY Two-Axis Joystick Module

This input module controls movement along the X and Y axes. It is commonly used with Arduino projects such as robotics, games, and interactive interfaces.

🔧 Listed specifications

• Supply: 5 V DC as listed
• Outputs: two analog axis signals (X and Y) and one digital push-button signal
• Dimensions: 34 × 34 × 15 mm
• Sensing elements: potentiometers for the X and Y axes, plus an integrated push button

⚙️ How it works

Two potentiometers detect movement along the X and Y axes. Moving the stick changes their resistance and the corresponding analog output voltages. Pressing the stick operates the integrated button.

💡 Applications

• Robot control
• Game interfaces
• Motor control
• Interactive projects

📌 Pinout

• VCC: supply (5 V as listed)
• GND: ground
• VRx: analog output for the X axis
• VRy: analog output for the Y axis
• SW: digital output for the push button

🔌 Using it with an Arduino Uno

Connect VCC and GND to Arduino power and ground. Connect VRx and VRy to analog inputs to read stick position, and connect SW to a digital input to detect presses.

Basic Arduino example

#define VRX_PIN A0
#define VRY_PIN A1
#define SW_PIN 2


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


void loop() {
  int xValue = analogRead(VRX_PIN);
  int yValue = analogRead(VRY_PIN);
  int buttonState = digitalRead(SW_PIN);


  Serial.print("X-axis: ");
  Serial.print(xValue);
  Serial.print(" | Y-axis: ");
  Serial.print(yValue);
  Serial.print(" | Button: ");
  Serial.println(buttonState);
  
  delay(100);
}

This sketch reads both analog axes and the button state, then prints the values in the Serial Monitor.

Components for the basic example

• Arduino Uno
• XY two-axis joystick module
• Connecting wires

Code overview

1. Initialization: Starts serial communication and configures the joystick button pin.
2. Read and display: Reads the analog axis values and button state and prints them in the Serial Monitor.

Basic wiring

• VCC: 5V (Arduino)
• GND: GND (Arduino)
• VRx: A0 (Arduino)
• VRy: A1 (Arduino)
• SW: D2 (Arduino)

Advanced Arduino example with an I2C LCD

#include <Wire.h>
#include <LiquidCrystal_I2C.h>


LiquidCrystal_I2C lcd(0x27, 16, 2);
#define VRX_PIN A0
#define VRY_PIN A1
#define SW_PIN 2


void setup() {
  lcd.begin();
  lcd.backlight();
  Serial.begin(9600);
  pinMode(SW_PIN, INPUT_PULLUP);
}


void loop() {
  int xValue = analogRead(VRX_PIN);
  int yValue = analogRead(VRY_PIN);
  int buttonState = digitalRead(SW_PIN);


  lcd.clear();
  lcd.setCursor(0, 0);
  lcd.print("X: ");
  lcd.print(xValue);
  lcd.setCursor(8, 0);
  lcd.print("Y: ");
  lcd.print(yValue);
  lcd.setCursor(0, 1);
  lcd.print("Button: ");
  lcd.print(buttonState ? "Released" : "Pressed");


  delay(100);
}

This example reads the X/Y axes and button and displays the values on an I2C LCD.

Library installation

To use the I2C LCD, install LiquidCrystal I2C through Arduino IDE’s Library Manager: open Sketch → Include Library → Manage Libraries, search for “LiquidCrystal I2C”, and install it.

Check the module pin labels and the voltage limits of the connected board before powering the circuit.
