Digital Smart Door Lock Security System Using Arduino Uno Microcontroller
Subject area: Science,Engineering and Technology · Area of research: Security System
Abstract
This research paper presents a microcontroller based digital door lock security system using keypad which will provide complete security solution to lives and properties at homes, schools and offices. The security system contains a 4X4 keypad input unit for entering the Personal Identification Number (PIN) and a display unit in form of Liquid Crystal Display (LCD) for visual display of information. It also contains a servo motor that serves as a switching for locking and unlocking the door and a programmed microcontroller that processes the input information and take appropriate action. When a user enters a PIN into the security system installed at any entrance, the system captures the PIN and compares it with the stored PINs for a match. If the captured PIN matches with any of the stored PINs, access granted is displayed on the LCD and the door opens; otherwise, access denied is displayed on the LCD and the door remains closed. For change of PIN, the user presses # button then the system asks for current PIN and matches it with stored PINs for a match. If a match was found, the user will be asked to enter the new PIN twice, else the user is asked for the current PIN again. The system recorded 100% success rate (SR) access granted to registered users and 100% failure rate (FR) for non- registered users. It is also system is cheap, affordable, small and relatively easy enough to install with just a couple of steps.
