Smart Attendance System

📑 Project Overview

This project demonstrates a simple RFID Attendance System using an Arduino UNO, RFID-RC522 module, and a 16x2 LCD (I2C Interface). The system reads RFID cards and displays the user information or attendance status on the LCD screen.

📦 Components Used

• Arduino UNO

• RFID-RC522 Module

• LCD 16x2 with I2C Adapter

• Jumper Wires

• Breadboard (optional)

• RFID Tags/Cards

🛠️ Working Principle

• When a valid RFID card/tag is brought near the RFID reader

• The system reads the unique ID (UID) of the card.

• It displays the UId, date and time.

🖥️ Libraries Required

Make sure to install the following libraries in Arduino IDE:

• MFRC522 (for RFID module communication)

• Wire.h (for I2C communication)

• LiquidCrystal_I2C (for LCD 16x2)

📌 You can install them through Arduino Library Manager.

🧩 Code Structure (Brief Overview)

Initialization: Setup LCD and RFID module.

Loop: Continuously check for a card presence.

UID: Scanned UID using RFID Reader.

Display Messages: Print appropriate messages on LCD.

⚡ Future Improvements

• Store multiple users in EEPROM.

• Add a Real-Time Clock (RTC) module to record timestamps.

• Send attendance data to a computer or cloud service via Wi-Fi module.

• Buzzer or LED indicators for feedback.
