Dual Axis Joystick Module KY-023
This joystick module is very similar to analog joysticks used for gaming. It is made by mounting two potentiometers perpendicular to each other. They are connected to a short stick centered by springs. These two potentiometers enable us to sense dual axis( XY ) movement of the stick. It also has a select button which is actuated when the stick is pressed down in the Z direction. This Joystick Module can be easily interfaced with Arduino Boards, Raspberry Pi and Microcontrollers.
