Joystick Module KY-023 - XY-Axis
This joystick module can be used in robotics projects and is very similar to analog joysticks for gaming. It is made of 2 potentiometers which are arranged at right angles to each other with a push button on the Z axis. The potentiometers allow you to register double axes (XY) The module can be used by Arduino, Raspberry Pi, and almost any other MCU such as PIC by means of an AD Converter
GND – Power Negative
+5V – 5V Supply voltage positive
VRx – X axis output voltage
VRy – Y axis output voltage
SW – Select button output voltage
The analog output is about 2.5V in both outputs VRx and VRy when the stick is in the center position. The outputs range from 5V and 0V when the stick is moved.
