Lesson 12 Joystick PS2

Introduction

A joystick is an input device consisting of a stick that pivots on a base and reports its angle or direction to the device it is controlling. Joysticks are often used to control video games and robots. A Joystick PS2 is used here.

Components

• 1 * SunFounder Uno board

• 1 * USB data cable

• 1 * Joystick PS2 module

• 1 * 5-Pin anti-reverse cable

Principle

This module has two analog outputs (corresponding to X and Y coordinates) and one digital output representing whether it is pressed on Z axis.

Experimental Procedures

Step 1: Build the circuit

The wiring between the Joystick PS2 and SunFounder Uno board:

Joystick PS2	SunFounder Uno
GND	GND
VCC	5V
Bt	7
x	A0
y	A1

Step 2: Open the code file

Step 3: Select correct Board and Port

Step 4: Upload the sketch to the SunFounder Uno board

Code

Now, push the rocker and the coordinates of X and Y axes displayed on Serial Monitor will change accordingly; press the button, and the coordinate of Z=0 will also be displayed.
