Password based door lock system using 8051 microcontroller is a simple project where a secure password will act as a door unlocking system.
Security door lock system project.
The system comprises of a keypad and 16x2 lcd.
The complete circuit diagram for our arduino based digital keypad door lock project is shown below.
183 security projects arduino uno alarm that detects movement alerts when triggered can be armed and disarmed via keypad and displays status on an lcd.
Circuit diagram for arduino keypad door lock.
The proposed system implements a password protected electronic lock that provides a great benefit over a traditional lock as well as great security.
However you can change this via coding later.
This door lock will only open the door when the user scans the right fingerprint that is recorded on the system but the door will remained close upon entering the wrong fingerprint.
Traditional lock systems using mechanical lock and key mechanism are being replaced by new advanced techniques of locking system.
In this study we have implemented a digital security system contains door lock system using passive rfid.
The door locking system functions in real time as when the user put the tag in contact with the reader the door open.
This is a simple arduino project.
A centralized system is being deployed for controlling and transaction operations.
First of all we start from the brain of this project which is the arduino uno board.
The arduino board is connected to an lcd and a servo motor.
At first arduino is initialized in stand by mode where it asks the user to enter the password to unlock the door.
How does the password security door lock system work.
In this video you can learn how to make a simple password based door lock system using arduino servo motor and 3 4 matrix.
