Dual-axis Joystick Module

  The dual-axis joystick module uses the metal button potentiometer from PS2 game controllers. This module features two analog output interfaces for the X and Y axes, which represent the positional offsets on each axis. The outputs are analog signals. The module also has one digital output that indicates whether the button on the Z axis is pressed, which functions as a digital switch. With this joystick module, users can easily control objects in 2D space. It is suitable for programming controllers, connecting to sensor expansion boards, and creating innovative remote interactive projects.

Specifications

Hardware Connection

1. The X-axis analog output is connected to the A0 analog input pin of the development board.
2. The Y-axis analog output is connected to the A1 analog input pin of the development board.
3. The button output is connected to the digital input pin 2 of the development board.
4. The power wire (+VCC) is connected to 5V.
5. The ground wire (GND) is connected to GND.

Usage Method

In the code, it implements reading the analog values of the X and Y axes, as well as checking whether the button is pressed.
