The Best DIY STEM Tutorials and Projects
OVERVIEW
In this project, we use a joystick to control LEDs, just like a game controller! Moving the joystick in different directions will turn LEDs on and off, helping us understand how input from sensors can be used to control outputs. It’s a fun way to learn about analog signals and Arduino programming! 🚀✨

Wiring Diagram
Here is a Complete Wiring Diagram along with Instructions for this Project
Program / Code
Code is Explained in the Comments of the Code
const int joystickX = A0;
const int joystickY = A1;
const int redLed = 3;
const int yellowLed = 5;
const int greenLed = 6;
const int buzzer = 4;
void setup() {
// put your setup code here, to run once:
pinMode(redLed, OUTPUT);
pinMode(yellowLed, OUTPUT);
pinMode(greenLed, OUTPUT);
pinMode(buzzer, OUTPUT);
}
void loop() {
// put your main code here, to run repeatedly:
int xValue = analogRead(joystickX);
int yValue = analogRead(joystickY);
int threshhold = 400;
//updirection
if (yValue < threshhold){
digitalWrite(yellowLed, HIGH);
digitalWrite(redLed, LOW);
digitalWrite(greenLed, LOW);
noTone (buzzer);
}
//downdirection
else if (yValue > 600){
tone(buzzer, 1000);
delay(50);
digitalWrite(yellowLed, LOW);
digitalWrite(redLed, LOW);
digitalWrite(greenLed, LOW);
}
// right direction
else if (xValue > 600){
noTone(buzzer);
digitalWrite(yellowLed, LOW);
digitalWrite(redLed, HIGH);
digitalWrite(greenLed, LOW);
}
// left direction
else if (xValue < threshhold){
noTone(buzzer);
digitalWrite(yellowLed, LOW);
digitalWrite(redLed, LOW);
digitalWrite(greenLed, HIGH);
}
}
