Joystick Module

img_joystick_pic

A joystick works by converting the movement of its stick into electronic signals that a computer can interpret.

To convey the full range of motion, the joystick measures the stick’s position along two axes: the X-axis (left to right) and the Y-axis (up to down). These X-Y coordinates precisely define the stick’s position, much like in geometry.

The joystick determines the stick’s position by tracking the movement of its shafts. In a traditional analog joystick, this is achieved using two potentiometers (variable resistors), which adjust resistance based on the stick’s position.

Additionally, the joystick includes a digital input that is triggered when the stick is pressed down.
