Joystick

Course Introduction

In this lesson, we will learn how to use the Joystick Module with Arduino.

Note

If this is your first time working with an Arduino project, we recommend downloading and reviewing the basic materials first.

Common Connections:

Joystick Module
SW: Connect to 8 on the Arduino.
VRY: Connect to A1 on the Arduino.
VRX: Connect to A0 on the Arduino.
GND: Connect to GND on the Arduino.
VCC: Connect to 5V on the Arduino.

Writing the Code

Note
You can copy this code into Arduino IDE.
Don’t forget to select the board(Arduino UNO R4 WIFI) and the correct port before clicking the Upload button.


/*
  The code reads values from a joystick module and prints them on the serial monitor.
  The joystick module has two analog axes (X and Y), which are connected to Arduino
  pins A0 and A1. The decimal form of the X and Y axis values is read and displayed
  on the serial monitor.

  Board: Arduino Uno R3(or R4)
  Component: Joystick Module

const int xPin = A0;  //the VRX attach to
