Lesson 29 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
- Several jumper wires
Experimental Principle
This module has two analog outputs (corresponding to X，Y biaxial offsets) and one digital
output representing whether it is pressed on Z axis. The module integrates power indicator
and can display operation condition.
In this experiment, we use the SunFounder Uno board to detect the moving direction of the
Joystick knob and pressing of the button.
