Door Lock using RFID and Arduino

This is an IoT-based system with Radio Frequency Identification System which supports door lock and unlock function. This door locking system helps registered users to lock or unlock the door. The door will get unlocked if the card is valid; otherwise, it will be locked. The Arduino board will run with the programming stored in it. The green LED will specify if the card is valid, and an acknowledgment message will be displayed on the LCD that the access is allowed, and the red LED will specify whether the card is invalid and will show an acknowledgment message that the access is denied.
