The KY-023 Dual-Axis Joystick Module is the standard interface for adding tactile, human-centric control to your electronic projects. At Electrapac, we recommend this module for developers building robotic arms, remote-controlled vehicles, or custom gaming consoles, as it provides intuitive 360-degree navigation in a compact package.

Product Overview

The KY-023 functions similarly to the thumbsticks found on PlayStation (PS2) controllers. It consists of two independent 10k potentiometers—one for the X-axis (horizontal) and one for the Y-axis (vertical). Additionally, the module features a tactile "click" button when the lever is pressed down, effectively giving you a 3-axis input (X, Y, and Z-button).

Key Features for Electrapac Customers

• Dual-Axis Analog Output: Provides a varying voltage based on the lever position. When centered, the voltage is approximately half of the input (2.5V on a 5V system).

• Integrated Push Button: The Z-axis switch is ideal for selecting menu items, firing "weapons" in a game, or resetting a robot's position.

• Spring-to-Center Design: The lever automatically returns to the neutral position when released, ensuring predictable control for navigation.

• Durable Construction: Built with a high-quality rocker mechanism designed to withstand thousands of directional movements.

• Breadboard Friendly: While the pins are on the bottom, the module can be easily connected using standard Dupont jumper wires.

Implementation Guide

• Reading the Values: Connect VRx and VRy to the Analog-to-Digital Converter (ADC) pins on your Arduino (A0 and A1). The output value will range from 0 to 1023.

• Deadzone Calibration: Because of mechanical tolerances, the center value might not be exactly 512. At Electrapac, we suggest coding a small "deadzone" (e.g., ignoring values between 500 and 525) to prevent accidental movement drift.

• Switch Wiring: The SW pin is an open circuit. When pressed, it connects to Ground. We recommend enabling the internal INPUT_PULLUP on your microcontroller to ensure a stable reading.

Primary Applications

• Robotics: Controlling the movement and gripper of a robotic arm.

• RC Vehicles: Steering and speed control for DIY cars and drones.

• Gaming: Creating custom HID (Human Interface Device) controllers for PC or mobile games.

• Menu Navigation: Using the X/Y axes to scroll through OLED or LCD screen menus.

• Pan/Tilt Camera Control: Smoothly moving a camera gimbal in two dimensions.
