Project V - 30. Arduino Interface with Analog Joystick

Arduino Interface with Analog Joystick

The Arduino UNO is used to read the data values of X and Y axis which are the output data of the joystick whose results are displayed on the LCD.

Hardware Requirement

• Arduino Uno Board
• Joystick Dual Axis Module
• LCD 16x2
• Power supply +5 Volt
• Jumper

Source Code/Sketch

#include <LiquidCrystal.h>
LiquidCrystal lcd(2, 3, 4, 5, 6, 7);
int joyX = A0;
int joyY = A1;
int value1 = 0;
int value2 = 0;
int SW = 8;
int led = 0;
void setup() {
pinMode(13, OUTPUT);
pinMode(SW, INPUT);
digitalWrite(SW, HIGH);
lcd.begin(16, 2);
lcd.print("Baca Joystick");
}
void loop() {
value1 = analogRead(joyX);
value2 = analogRead(joyY);
lcd.setCursor(0 ,1);
//X=46 --> 1018
lcd.print("X:");
lcd.print(value1);
//Y=46 --> 1018
lcd.print(" Y:");
lcd.print(value2);
lcd.print(" ");
if(digitalRead(SW)==0){
delay(100);
led=!led;
digitalWrite(13, led);
}
delay(100);
}

How it Works

1. Connect the Arduino with Peripherals needed.
2. Plug in the Power Source on the device.

3. Add some library if needed

4. Compile and upload the script program above to your arduino.
5. LCD will displays X and Y values, while the SW key is use to turn on and off LED 13 Arduino.
