Code for Smart Home Automation with Arduino
Certainly! Below is a simple Arduino code snippet to get you started with a basic smart home automation project. This example uses an Arduino board, an LED as a representative device, and a push button to simulate a sensor input.
// Include necessary libraries
#include <Arduino.h>
// Define constants
const int ledPin = 13; // Pin connected to the LED
const int buttonPin = 2; // Pin connected to the push button
// Variables
int buttonState = 0; // Variable to store the button state
void setup() {
pinMode(ledPin, OUTPUT); // Set the LED pin as an output
pinMode(buttonPin, INPUT); // Set the button pin as an input
}
void loop() {
buttonState = digitalRead(buttonPin); // Read the state of the button
// Check if the button is pressed
if (buttonState == HIGH) {
digitalWrite(ledPin, HIGH); // Turn on the LED
delay(1000); // Wait for 1 second
digitalWrite(ledPin, LOW); // Turn off the LED
}
}
