OVERVIEW
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.

CONNECTIONS
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.
THE CODE
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.
// Arduino pin numbers
const int SW_pin = 2; // digital pin connected to switch output
const int X_pin = 0; // analog pin connected to X output
const int Y_pin = 1; // analog pin connected to Y output
void setup() {
pinMode(SW_pin, INPUT);
digitalWrite(SW_pin, HIGH);
Serial.begin(115200);
}
void loop() {
Serial.print("Switch: ");
Serial.print(digitalRead(SW_pin));
Serial.print("\n");
Serial.print("X-axis: ");
Serial.print(analogRead(X_pin));
Serial.print("\n");
Serial.print("Y-axis: ");
Serial.println(analogRead(Y_pin));
Serial.print("\n\n");
delay(500);
