What is needed to create a basic RFID door lock system?
To create a basic RFID door lock system, use an RFID reader module to read RFID tags or cards. Connect the reader to a microcontroller that processes the RFID data and controls a door lock mechanism (like a solenoid lock) via a driver or a relay. Implement a security protocol in the microcontroller to validate the RFID tags. Add a power supply circuit with backup options for reliability.
