This joystick module provides two analog position outputs for the X and Y axes, plus a digital pushbutton switch on SW. It is typically connected to power and ground, with VRX and VRY read by analog inputs and SW read as a digital input.
| Pin | Signal | Description |
|---|---|---|
GND |
ground | Ground reference for the joystick module and pushbutton circuit |
VCC |
power | Power supply input for the joystick potentiometers, typically 5V or 3.3V |
VRX |
analog | Analog X-axis output from the joystick potentiometer |
VRY |
analog | Analog Y-axis output from the joystick potentiometer |
SW |
digital | Digital pushbutton output from pressing the joystick, commonly active-low |
