"RFID-Based Door Lock System "

The RFID-Based Door Lock System is an advanced access control solution designed to enhance security and convenience. The system leverages RFID (Radio Frequency Identification) technology to authenticate users and control access to a door. It comprises an Arduino microcontroller, an RFID reader module, an electric door lock, and an LCD display.

When an RFID card or tag is presented to the reader, the Arduino retrieves the card's unique ID and checks it against a pre-programmed list of authorized IDs stored in its memory. If the ID matches, the system activates the electric door lock, granting access, and displays "Access Granted" on the LCD. Conversely, unauthorized attempts display "Access Denied" and keep the door locked. The system allows for adding or removing authorized IDs, making it flexible and scalable.

This project eliminates the need for traditional keys, providing a more secure and user-friendly alternative for access control in homes, offices, and other secure areas. The addition of visual feedback via the LCD enhances user experience, while its adaptability ensures the system can cater to various security needs.
