Using an Analog Joystick with an Arduino

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);
}

      You need to make sure that your computer’s serial read frequency and your serial frequency are the same. What might fix it is changing the line “Serial.begin(115200);” to “Serial.begin(9600);.” In the video he used 115200 for some reason but 9600 is the most common frequency and I think is also the default in Arduino IDE. The serial frequency is what you declare in your code, and the computer’s read frequency is the number that you select in the drop down menu of the serial monitor in Arduino IDE.
