Introduction

Arduino is now well-known in the exciting world of DIY projects and electronics. With the help of this open-source microcontroller platform, hobbyists can build a variety of cutting-edge devices. This post will discuss the simple yet fascinating Arduino project of using a push button to drive an LED. We’ll take you step-by-step through the procedure, making it approachable for novices and entertaining for more seasoned enthusiasts.

Arduino with Push Button and LED

In this note, we’ve taken a step-by-step journey into the world of Arduino, exploring how to control an LED with a push button. This project is an excellent starting point for anyone interested in electronics and programming. It demonstrates the fundamental concepts of input and output in a fun and interactive way.

What We Need

The components that are required to make this project

• Arduino Board
• One LED
• One 100 ohm Resistor
• One Push Button
• Jumper Wires
• Breadboard
• USB cable

Circuit Connection

Code

This is the code for Arduino with Push Button and LED.

// constants won't change. They're used here to set pin numbers:
const int buttonPin = 13;  // the number of the pushbutton pin
const int ledPin = 9;    // the number of the LED pin

// variables will change:
int buttonState = 0;  // variable for reading the pushbutton status

void setup() {
  // initialize the LED pin as an output:
  pinMode(ledPin, OUTPUT);
  // initialize the pushbutton pin as an input:
  pinMode(buttonPin, INPUT);
}

void loop() {
  // read the state of the pushbutton value:
  buttonState = digitalRead(buttonPin);

  // check if the pushbutton is pressed. If it is, the buttonState is HIGH:
  if (buttonState == HIGH) {
    // turn LED on:
    digitalWrite(ledPin, HIGH);
  } else {
    // turn LED off:
    digitalWrite(ledPin, LOW);
  }
}
