Password Based Door Lock System Block Diagram

In this password based door locking system project a keypad is arranged to open and close the door.

Password based door lock system block diagram.

Block diagram of password based door locking system a. This block gives the entered code signals to the microcontroller. After entering a password if it matches with the stored one then the door will unlock for a limited period of time. Password based door lock system using arduino simulino uno schematic diagram read smart phone controlled home automation using arduino the key pad library for the arduino uno available in this link keypad this library is setup to do every function for the keypad.

Password based door lock system using 8051 microcontroller is a simple project where a secure password will act as a door unlocking system. If another person arrives it will ask to enter the password again. This is the cpu central processing unit of our project. This system demonstrates a password based door lock system using arduino uno wherein once the correct code or password is entered the door is opened and the concerned person is allowed access to the secured area.

The various functions of microcontroller are like. The keypad is an input device that helps to enter a code to open the door. Reading the digital input from keypad. If any unauthorized person enters a wrong password in an attempt to open the door then this system immediately switches a buzzer.

We are going to use a microcontroller of 8051 family. If the password is wrong then door would remain l ock ed enyi.
