Password Door Lock (LabVIEW)

Password Protected Door Lock System

Project Overview

This project implements a password-protected door lock system using LabVIEW and embedded hardware. The system enhances security by allowing access only to users who enter the correct password via a keypad interface.

Key Features

• User authentication through a numeric keypad.
• Visual feedback using LEDs or an LCD display for correct/incorrect password entry.
• Integration with a relay or servo motor to control the door lock mechanism.
• LabVIEW interface for monitoring and controlling the system.

How It Works

The user enters a password using the keypad. The LabVIEW program reads the input and compares it to a predefined password. If the password matches, the system triggers the door lock to open and provides a success indication. If the password is incorrect, access is denied and an error message is displayed.

Applications

• Home and office security systems
• Access control for restricted areas
• Educational demonstration of embedded security concepts

Conclusion

The Password Door Lock project demonstrates the integration of software (LabVIEW) and hardware for practical security solutions. It can be further enhanced with features like password change, logging, or remote access.
