IoT Attendance System 🌐

Description

The IoT Attendance System is here to make tracking attendance at Creative a breeze! 🚀 We’ve hooked up an RFID scanner with a Wi-Fi module to read ID cards and send the data straight to a Google Sheet. The system features LEDs, a buzzer for alerts, and email notifications for banned individuals. 📧 Plus, there’s an MIT app that lets managers log in, see who’s around in real time, and search through attendance history. 📱

How It Works

1. RFID Scanning: Employees swipe their ID cards in front of the RFID sensor. 🆔

   • The NodeMCU uploads the card data to the Google Sheet. 📊
   • It also sends serial messages to the Arduino Uno to handle different scenarios (employee, manager, or banned). 🛠️

2. LED and Buzzer Alerts:

   • Employees/Managers: Green LEDs flash one by one until the LCD shows their name. 💚🔆
   • Banned Individuals: Red LED blinks, buzzer sounds, LCD displays "ALERT! Intruder detected!", and an email is sent to all employees with the banned person’s ID. 🚨🔴📧

3. MIT App:

   • Pulls data from the Google Sheet and displays it. 📈
   • Login: Only the manager can log in (Username: nora, Password: 1234). 🔐
   • Features:
     • Shows who’s in the building and alerts if an intruder is detected. 🏢👀
     • Displays a history log with details (ID, Name, Age, Date, Time) and lets you search for specific employee records. 📜🔍
