Password Controlled Door Lock System using Keypad and Arduino UNO
The Project
We created a Password Controlled Door Lock System using an Arduino Uno, 4x4 keypad, and a servo motor. The user enters a password through the keypad, and if correct, the servo unlocks the door. Inspiration: Inspired by digital security systems used in offices and homes, I wanted to build a basic yet effective access control system that replaces traditional keys with secure password entry. What was difficult? The main challenge was programming the Arduino to accurately compare user input with the stored password, handle incorrect attempts, and control the servo for smooth locking and unlocking. Applications: Home security and office cabins School lockers or personal drawers Smart access systems for projects or prototypes Low-cost electronic security for personal use
