Joystick PS2 Module

Introduction

The joystick PS2 module two lines of analog output (X, Y) and one of digital output (Z). The cross rocker is a bidirectional 10k resistor; its resistance changes with different directions. Push the joystick towards different directions and the voltage read increases or decreases; press it down, then the output is low level and the corresponding LED lights up; otherwise it stays off.
The schematic diagram of the module is as follows:

Application

The module can be applied to convenient control of objects (like a two-degree of freedom servo mount) to move in a two-dimensional space. It can be used in the remote controller for many robot projects
