Arduino-Based Multi-Function Home Automation Project

🌟 Project Overview

This project implements a multi-functional home automation system using Arduino. It integrates various sensors and actuators to automate and simplify daily tasks.

✨ Features

1. LED Brightness Control

   • Adjusts LED brightness inversely to light intensity using an LDR.

2. Servo Motor Control

   • Operates doors using two IR sensors and a keypad for input.

3. Temperature Monitoring

   • Activates a fan when the temperature exceeds a threshold.
   • Triggers a buzzer alarm for high temperatures, resettable via a push button.

4. LCD Display

   • Real-time display of temperature, brightness, and password validation.

⚙️ How It Works

1. LDR-Based LED Control:

   • The LDR measures ambient light intensity, and the LED brightness is adjusted inversely using PWM signals.

2. IR and Servo Control:

   • Two IR sensors control the servo motor's movement in response to object detection.

3. Temperature Monitoring:

   • Activates a fan for temperature regulation.
   • Triggers an alarm if the temperature exceeds a high threshold until manually reset.

4. LCD Display:

   • Displays temperature, brightness, and password-related messages.
