The Dual Analog PS2 Joystick Module is a compact, versatile input device designed for Arduino UNO R3 and other microcontroller projects. It features a 2-axis analog joystick (X and Y) plus a built-in push button (Z-axis), providing precise directional control and a selectable action in a single, easy-to-integrate module. It is an ideal solution for robotics, game controllers, camera pan-tilt systems, menu navigation, and DIY electronics projects.

At the heart of the module is a PS2-style thumbstick with two 10kΩ potentiometers arranged perpendicularly to sense movement along the X and Y axes. Each axis outputs an analog voltage that varies with the joystick’s position, centered at approximately VCC/2 when the stick is at rest. Moving the stick changes the voltage on each axis, allowing your microcontroller to read the precise position and direction of movement. The built-in push button activates when the stick is pressed down, providing an additional digital input for selection or action commands.

The module features five pins for easy connection: VCC, GND, VRx (X-axis analog output), VRy (Y-axis analog output), and SW (button digital output). The analog outputs connect directly to your microcontroller’s ADC pins, while the button output connects to a digital input pin. This simple interface makes the module compatible with Arduino, ESP32, STM32, Raspberry Pi, and other microcontrollers.

The compact form factor with mounting holes allows easy integration into custom enclosures, handheld controllers, and robot chassis. The ergonomic thumbstick design provides comfortable, precise control for extended use. The module operates from a 3.3V to 5V DC supply, making it compatible with both modern low-power microcontrollers and traditional 5V systems.

The Dual Analog PS2 Joystick Module is widely used in robotics, RC vehicles, game controllers, camera gimbals, pan-tilt mechanisms, menu navigation systems, robot arm control, and educational STEM projects. It is also popular in DIY electronics and maker projects where precise directional input is required.

Important Note: The joystick’s analog outputs are centered at approximately VCC/2 when at rest. In your code, you should calibrate the center position and apply a dead zone to prevent drift or unintended movement. The module is not waterproof and should be kept dry. For long-term reliability, avoid applying excessive force to the thumbstick beyond its mechanical limits.

Whether you are building a robot, a game controller, or an interactive project, the Dual Analog PS2 Joystick Module provides a reliable, affordable solution for precise 2-axis control with button input. It is suitable for individual makers, students, and businesses purchasing in bulk for product development or educational programs.

Usage

Getting Started

  1. Connect power — Supply 3.3V or 5V DC to the VCC pin and GND to ground.

  2. Connect the analog outputs — Connect VRx to an analog input pin (e.g., A0 on Arduino) and VRy to another analog input pin (e.g., A1).

  3. Connect the button — Connect SW to a digital input pin (e.g., D2 on Arduino). Enable the internal pull-up resistor if needed.

  4. Upload a test sketch — Read the analog values from VRx and VRy, and the digital state from SW. Observe the values change as you move the joystick and press the button.

  5. Calibrate the center — Record the resting values of VRx and VRy (typically around 512 on a 10-bit ADC). Use these as your center reference.

  6. Apply a dead zone — In your code, ignore small movements near the center to prevent drift and unintended input.

Q: What is the Dual Analog PS2 Joystick Module used for?

It is a 2-axis analog joystick with a push button, used for robotics control, game controllers, camera gimbals, menu navigation, and educational STEM projects.

Q: How many axes does the joystick have?

It has 2 analog axes (X and Y) plus a digital push button (Z-axis) for selection and action commands.
