Description
A Password-Based Door Lock System using Arduino is a secure access solution that uses a keypad to enter a pre-set password to unlock doors, ideal for homes, offices, and restricted areas. This project typically involves an Arduino microcontroller connected to a 4×4 keypad and servo motor. When the correct password is entered, the servo motor unlocks the door for a set period. If an incorrect password is entered multiple times, the system can be programmed to trigger an alert, adding an extra layer of security. Simple, affordable, and customizable, this Arduino-based smart lock is a great project for beginners in IoT and embedded systems.
