Dual Axis XY Joystick Module

Dual Axis XY Joystick Module - Analog Position Sensor with Push Button Switch

The Dual Axis XY Joystick Module, often referred to as the PS2 Joystick Breakout Sensor (KY-023), is a simple yet effective interface for controlling movement and position in two dimensions. This compact module is constructed with two 10kΩ potentiometers mounted perpendicularly (one for the X-axis and one for the Y-axis), which translate the physical deflection of the joystick stick into corresponding analog voltage signals (VRx and VRy).

When interfaced with a microcontroller’s Analog-to-Digital Converter (ADC), these pins provide proportional voltage readings: approximately 2.5V when the stick is centered, 0V at one extreme, and 5V at the opposite extreme. Furthermore, the joystick includes a push-button switch (SW pin) that activates when the stick is pressed down, providing a critical third dimension of digital input (Z-axis). Its auto-return-to-center feature and straightforward 5-pin interface make it an immediate choice for robotics and gaming-style controls in DIY projects.

🔧 Key Features  

• Input Type: Dual-Axis Analog Position (X and Y) and Single Digital Input (SW).
   
• Sensing Elements: Two 10kΩ Potentiometers (Voltage Dividers).
   
• Analog Output: VRx and VRy pins output 0V to 5V (2.5V centered with 5V supply).
   
• Digital Output: SW pin toggles LOW when the stick is pressed (with pull-up enabled).
   
• Design: Automatically returns to center position when released.
 
• Compatibility: Works with microcontrollers operating at 5V or 3.3V.
 

💡 Applications

• Remote control of RC vehicles, rovers, and drone systems.
   
• Pan and Tilt control for cameras and robotic arms.
 
• Interface device for custom Game Controllers and simulators.
 
• Navigation control for menus on LCD or OLED displays.
