Abstract

Abstract: This research aims to design and implement an integrated smart door lock system based on embedded systems technology to provide advanced home security at a minimal cost. The proposed system utilizes the Arduino Uno as a central processing unit, with the core software architecture developed entirely within the Arduino IDE environment using (C/C++) programming. This approach facilitated the construction of sophisticated algorithms for access control and task management. The primary contribution of this work lies in the execution of a comprehensive engineering simulation within the Proteus environment. A virtual electronic circuit was built to accurately replicate real-world performance, encompassing the testing of the Passive Infrared (IR) motion sensor, data processing from the Keypad, and wireless control via the Bluetooth module (HC-05) through the Virtual Terminal. Additionally, the simulation monitored the mechanical actions of a Servo Motor representing the door latch. The simulation successfully validated the software-hardware compatibility and the effectiveness of the "Lockout Mode" algorithm after three failed attempts. "Wireless control was activated by linking the Bluetooth module to a smartphone application (Serial Bluetooth Terminal). This allowed for sending programming commands and receiving real-time status alerts directly on the application interface, with a coverage range of up to 10 meters, enhancing the system's realism and ease of use in the field."
