Abstract :
This paper presents the design and development of a low-cost, microcontroller-based door locking system utilizing
an Arduino Uno, a keypad for password input, an LCD for user feedback, and a servo motor to simulate a locking
mechanism. The project serves as a practical exploration of fundamental concepts in embedded systems and access control.
The system's architecture, hardware integration, and software implementation for password entry, verification, and
actuation are detailed. Functional testing demonstrates the successful operation of the core components, highlighting the
potential for keyless entry and basic security enhancement. The paper also discusses the system's limitations, including
security vulnerabilities and the non-robust locking mechanism, and proposes avenues for future work such as enhanced
security protocols, multi-user support, and integration with smart home systems. This work contributes to the
understanding of basic electronic access control principles and the capabilities of low-cost microcontroller platforms in
security applications.
