Abstract

This study addresses the security vulnerabilities of university laboratory rooms due to conventional mechanical keys. The purpose of this research is to design and implement a cost-effective, microcontroller-based smart door lock system integrated with real-time audit logging and an alarm mechanism. The system was developed using the prototyping method, encompassing requirements analysis, electronic circuit design, hardware assembly, software development via Arduino IDE, and quantitative performance evaluation. The prototype integrates an Arduino Uno, a 3x4 keypad, an SG90 servo motor, a DS1307 Real-Time Clock (RTC), a buzzer, and an LCD. Performance tests demonstrate high reliability with a 0.00 system error rate. The system achieves a fast total response time ranging from 191 ms to 212 ms for user validation and physical access execution. Power consumption analysis shows the prototype operates efficiently, requiring 0.65 Watts during idle states and peaking at 0.80 Watts when active. Every access attempt is systematically recorded into the local EEPROM with an average write speed of 44 µs. The primary contribution of this research is the successful integration of localized, real-time audit logging, multi-stage password validation, and automated lockout alarms into a single, low-cost microcontroller architecture without internet dependency. This provides a highly functional, secure, and easily adoptable reference for institutional laboratory access control.
