Nov 10, 2020 · The main objective of this project is to replace the traditional door lock system where we use mechanical lock and key mechanism by the password based door lock system. Arduino UNO: The Arduino Uno-board is a 8 bit-microcontroller. It has I/0 pins including both digital and analog pins.

Password Based Door Lock System is designed using ARDUINO UNO where in once the correct code or password is entered, the door is opened and the concerned person is allowed access to the secured area.

Learn how to make a door lock system using password with keypad and electromagnetic lock. When the door is unlocked by a correct password, It keeps the door unlocked for 20 seconds, and then automatically lock the door again. The Arduino code supports multiple passwords.

Feb 2, 2025 · This code implements a Password-Based Door Lock System using an Arduino Nano, a 4×4 keypad, an LCD, a servo motor, a buzzer, and two LEDs. The system allows users to set a password during the first boot, enter the password to unlock the door, and change the password by entering a master password.

We can make these digital doors by using “Password” which is more secure than traditional lock system. In this project we have make a “Password Based Door-Locking System” using an Arduino. It will be more efficient for the peoples in the field of security.

Apr 27, 2024 · An Arduino Based Door Lock System is a project where you can secure your doors with a password. Traditional lock systems which are using mechanical locks are replaced by modern technologies. These techniques are electrical and highly intelligent.

Oct 23, 2023 · We can create a reliable and adaptable door locking system that requires a strong password to open by combining an Arduino, a keypad, and an L298 motor driver. Let’s look at the parts needed and how to make this keypad door lock. The simulation highlights the main functions of the system and offers a hands-on explanation of how it works.

This document describes a password-based door lock system using an Arduino board. The system uses a keypad to input a password, which is checked by the Arduino against a stored password. If the passwords match, the Arduino signals a motor driver to activate a DC motor and unlock the door.

Jun 9, 2020 · Password-Based Digital Door Lock Security System, Project Concept, Block Diagram, Circuit diagram, working principle, and Arduino code.

Jul 20, 2020 · Arduino controls the entire process, such as taking the password from a keypad module, comparing passwords, changing passwords, turning the servo motor, and sending the status to the LCD display. The keypad is used to enter the password.
