Smart Door Lock System (Bluetooth, Arduino)

The Smart Door Lock System integrates Bluetooth technology with Arduino to provide secure and convenient access control. The system consists of a Bluetooth module (such as HC-05) connected to an Arduino microcontroller, which controls the door lock mechanism. Users can unlock the door using their smartphones by sending a Bluetooth signal to the system. The system compares the Bluetooth address of the device with a stored authorized list, and if a match is found, the door unlocks. This project eliminates the need for physical keys and offers a more secure and customizable method of access control. The system can also be integrated with a mobile app to provide features such as remote locking/unlocking, access logs, and notifications. Additionally, the system can be extended to include multiple users, with each user having a unique Bluetooth address. This smart door lock system is ideal for home security, office environments, and rental properties, providing an easy-to-use and secure access solution.
