Joystick Module(KY-023)

This module functions as a joystick, changing its x and y-axis values according to the resistance variations. Pressing the center button acts as a switch. It's commonly used in remote control cars, drones, and other applications requiring movement control.

Specifications

• Operating Voltage: 3.3V ~ 5V
• Analog output for x and y axes
• Digital output for the z-axis switch (without pull-up resistor)

Example Required Hardware

• Arduino board
• Jumper cables
• Joystick Module
• LCD 1602

Connection

Arduino	LCD	Joystick Module
5V	VCC	5V
GND	GND	GND
A1		VRx
A0		VRy
D2		SW
A4	SDA
A5	SCL

Example Code

This example displays the joystick's coordinates and switch state on an LCD screen.

Please refer to the link for instructions on using the LCD.

#include <Wire.h>
#include <LiquidCrystal_I2C.h>

const int xAxis = A1;
const int yAxis = A0;
const int zSwitch = 2;

void setup() {
  pinMode(zSwitch, INPUT_PULLUP);
  lcd.init();
  lcd.backlight();
  lcd.setCursor(0, 0);
  lcd.print("X:");
  lcd.setCursor(8, 0);
  lcd.print("Y:");
  lcd.setCursor(0, 1);
  lcd.print("Z : ");
}
