How to connect and use an Analog Joystick with an Arduino

In this article, you will learn how to connect and use an Analog Joystick with an Arduino.

This joystick module maybe the best choice for your controller of DIY project. It has two analog input pins to control X, Y axis and also has button input, someone may call it Z axis, but it only input digital signal with 0 or 1.

Components Required

Arduino Uno    [ Amazon / Gearbest / Banggood ]

Joystick module [ Gearbest / Amazon / Banggood ]

Jumper wires x5  [ Amazon / Gearbest / Banggood ]

Procedure

Step 1: Build the circuit

Joystick Module                                 Arduino Uno
SW ————————————– D2
VRx ————————————- A0
VRy ————————————- A1
+5V ————————————- 5V
GND ———————————— GND

Step 2: Download the code

Step 3: Upload the code to your Arduino Uno (any Arduino board)

Now, push the rocker and the coordinates of X and Y axes displayed on Serial Monitor will change accordingly, press the button, and the coordinate of Z=0 will also be displayed.

// Arduino pin numbers
int SW = 2; // digital pin connected to switch output
// A0-> X ; A1-> Y;
void setup() {
  pinMode(SW, INPUT);
  digitalWrite(SW, HIGH);
  Serial.begin(115200);
}
void loop() {
  Serial.print("Switch:  ");
  Serial.print(digitalRead(SW));
  Serial.print("\n");
  Serial.print("X-axis: ");
  Serial.print(analogRead(A0));
  Serial.print("\n");
  Serial.print("Y-axis: ");
  Serial.println(analogRead(A1));
  Serial.print("\n");
  delay(500);
}
