Build a DIY IoT Smart Door Lock! (NodeMCU ESP8266 + RFID)

Learn how to build a DIY IoT Smart RFID Door Lock System using the NodeMCU ESP8266 and the new Blynk 2.0 IoT platform! In this step-by-step tutorial, we connect an RFID MFRC-522 module, a 12V solenoid lock, and a relay to create a secure smart door lock that you can remotely monitor and control from your phone (iOS & Android) anywhere in the world.

🌟 Key Features of this IoT Door Lock:
Global Remote Access: Live monitor and control your door lock from anywhere using the Blynk app.

User Management: Authorize and deauthorize specific RFID users remotely.

OTA Updates: Over The Air configuration updates without plugging into a PC.

Smart Storage: Easily reconfigure WiFi credentials stored in EEPROM without hardcoding.

Alerts & Indicators: Blinking LED for WiFi response and a built-in buzzer alert system.
