Password Based Door Lock System

Password based door lock system using arduino simulino uno code include include initialize the library with the numbers of the interface pins liquidcrystal lcd 9 8 7 6 5 4.

Password based door lock system.

Lie back and relax for your abode and workplace are now protected from attempted break ins with this easy to make diy security mechanism. Download the library for keypad h from below. Now read the five digit password from the user. Password based door lock system algorithm initially declare the port1 to lcd data pins and control pins rs and e to p3 0 and p3 2.

The necessity of a low cost electronic home security system designed in coordination with other security measures is always there in our society to reduce the risk of home intrusion. Password based door lock circuit design uses five major components a microcontroller a relay a dc motor a 4 3 matrix keypad and a lcd. A simple yet effective means to safeguard your home and office by preventing others from entering your room without the correct password. This block gives the entered code signals to the microcontroller.

It will add the good security. The main component in the circuit is 8051 controller. Const byte rows 4. Four rows const byte cols 4.

Keeping this problem in mind we are working on a project on. Password and onetime password based door lock system such an automatic lock system consists of electronic control assembly which controls the output load through a password. Then display the message enter password on lcd. The project password detector can be used to automate the door locking process so the user need not to carry the door lock keys along with them they need to just remember the password and use it later to open the door.

Compare the entered password with the. This controller requires a supply voltage of 5v dc. Four columns define the cymbols on the buttons of the keypads char hexakeys rows cols 7 8 9. Also declare port2 to.

This output load can be a motor or a lamp or any other mechanical electrical load. You can simply copy paste the code using arduino ide. The code for password based door lock security system using arduino keypad is given below. Password based door locking system with 8051 principle behind the project.

The simply compile it then finally upload it to the atmega328 microcontroller. Password based door locking system the operation of this system can be described by the above block diagram which consists of blocks as keypad a buzzer an lcd a motor driver and a stepper motor. When power supply is turned on a message enter your password. In this project 4 3 keypad is used.

Here at89c51 microcontroller is used and it is an 8 bit controller.
