Abstract
The demand for affordable and customizable security systems continues to grow as embedded microcontrollers become more accessible. This study explores the development of a Smart Door Lock System using Arduino Uno, implemented entirely in Tinkercad’s block-based programming environment. The system integrates a potentiometer acting as an analog password input, a 16×2 LCD for real-time feedback, an LED indicator for status signaling, and a servo motor as the primary locking mechanism. Results from three test scenarios̶valid input, invalid input, and user inactivity̶demonstrated consistent and accurate system performance. Findings highlight the educational value of analog-to-digital processing and conditional logic for early embedded systems learning, while identifying limitations and opportunities for future enhancement.
