✅ Features: Detects and displays cardholder's name via LCD Sends name, date, and time to a Google Sheet instantly via WiFi Uses RFID module, NodeMCU (ESP8266), and NTP server for accurate timestamps Fully portable and can be extended with IoT features like alerts or face ID later! 🧠 Faced some interesting debugging challenges — especially with URL encoding names so they’re properly received by Google Sheets. Learned a lot about HTTP GET requests, NTP time syncing, and memory management on microcontrollers. 📚 Tools & Skills Used: Arduino IDE, C++ NodeMCU (ESP8266) RFID RC522 LiquidCrystal I2C Display Google Apps Script (for Sheets Integration) NTPClient Library for Real-time Clock Debugging & Networking logic This project is just the start! 🔥 I’m planning to enhance it further with features like face recognition, Google Calendar integration, and maybe even a mobile app dashboard using Firebase or Blynk.
