Using an Analog Joystick with an Arduino
Analog joysticks are a great way to add some control in your projects.
In this tutorial we will learn how to use an analog joystick module.
We need 5 connections to the joystick.
The connection are : Key, Y, X, Voltage and Ground.
“Y and X” are Analog and “Key” is Digital. If you don’t need the switch then you can use only 4 pins.
Analog joysticks are basically potentiometers so they return analog values.
When the joystick is in the resting position or middle, it should return a value of about 512.
The range of values go from 0 to 1024.
Just copy and paste the above code in the Arduino IDE to program your Arduino.
