PS2 Joystick Module Dual Axis Analog

Two potentiometers, one per axis, are what actually drive this module: as the stick moves, each pot's resistance changes proportionally, giving a smooth analog reading on both X and Y rather than a handful of discrete directions the way a directional pad would. A self-centering spring returns the stick to a neutral midpoint reading whenever released, so a project always has a reliable zero to measure movement against.

A push-button built into the stick itself - press straight down to activate it - adds a third input without a separate button taking up board space, commonly used as a select or boost action alongside the directional reading.

Common uses are RC car and robot directional control, menu navigation with proportional rather than discrete input, and any project needing smooth two-axis analog control from a single compact component.
