In this project, we will make a Password-Based Door Lock Security System using Arduino, a keypad, a servo motor, an LCD, and a buzzer. With rising concerns about security, this digital password-based lock can be an effective way to safeguard homes or lockers.

This system will unlock the door only when the correct password is entered. It’s a simple and effective way to keep your home or valuables safe.

In the Password Based Door Lock Security System, the Arduino controls the whole system. The keypad is used to enter the password, and the LCD shows messages like “Enter Password” or “Access Granted.” The buzzer makes sounds to give feedback, like when a button is pressed or the password is wrong. If the correct password is entered, the servo motor unlocks the door and locks it again after a few seconds. This project is easy to build and very useful for security.
