This project combines two key technologies: RFID (Radio Frequency Identification) for security and solar tracking for energy efficiency. Here’s an outline of how the project can be structured and built.

1. Project Overview
This project aims to create an RFID-based security system that will control access to a door or an area. Additionally, a solar tracker is incorporated to maximize the efficiency of solar energy collection by adjusting the solar panel's position based on the sun's location.

Components Required:

Microcontroller: Arduino nano - https://amzn.to/4iQ1gCE
RFID Module: MFRC522 or similar for reading RFID tags
RFID Tags/Cards: For authorized access - https://amzn.to/4iQHiHA
Servo Motor: For rotating the solar panel in the solar tracking system - https://amzn.to/3ZGW7nm
LDR (Light Dependent Resistor): For detecting sunlight intensity and adjusting the solar panel - https://amzn.to/3Du2Mdh
Solar Panel: For generating power - https://amzn.to/4gOVmQ6
Power Supply: To power the system, including the Arduino and solar panel - https://amzn.to/3ZRIAJI

2. System Features

RFID Security: The system scans an RFID tag or card when placed near the reader. If the card is authorized, the door or access point will open. If unauthorized, the system will trigger an alarm.
Solar Tracker: The solar panel will track the position of the sun throughout the day using LDR sensors. The solar panel will adjust its position for optimal energy generation by rotating the servo motor.
Integrated Security and Energy Efficiency: This combined system ensures that access control is secure while optimizing energy usage through the solar tracker.

3. Working of the System

RFID Security System:
Scanning Process: The user holds an authorized RFID card near the reader. The RFID reader (MFRC522) scans the RFID card’s unique ID.
Microcontroller Processing: The ID is compared with a pre-programmed list of authorized users stored in the Arduino or Raspberry Pi.

Access Decision:
If the card is authorized, the system triggers a relay to unlock the door.
If unauthorized, a buzzer sounds and a message is displayed on the LCD, and the door remains locked.

Solar Tracker Mechanism:
Light Detection: Two LDRs (Light Dependent Resistors) are placed on opposite sides of the solar panel. These LDRs detect the intensity of light falling on each side.

Servo Movement: Based on the light readings, the microcontroller controls the servo motor to rotate the solar panel towards the light source (the sun).
Tracking Adjustment: The panel adjusts its angle in real-time throughout the day to keep facing the sun, ensuring maximum solar energy absorption.
