Password Based Door Lock System Using Pic18 Microcontroller

In our diy digital lock system 8051 89c51 89c52 is our intelligent unit.

Password based door lock system using pic18 microcontroller.

This system demonstrates a password based door lock system using 8051 microcontroller wherein once the correct code or password is entered the door is opened and the concerned person is allowed access to the secured area. Password based door locking system design uses five major components a microcontroller an l293d motor driver a dc motor a 4 4 matrix keypad and an lcd. This controller requires a supply voltage of 5v dc. Here at89c51 microcontroller is used and it is an 8 bit controller.

We are widely familiar with the password based e locks and might have installed in our house. In electronic door locks there s some password which is only known to some persons. 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. In this way a simple door lock system can be implemented with the use of a microcontroller.

If the person attempting to open the door enters a wrong password then the microcontroller switches the alarm for further course of action. All the processing s will be done by 8051 microcontroller. We all know about electronic door locks as we have seen them in many homes. But we are going for electronic locks made by any company when you can make one by your own.

Electronic code lock system circuit design. Hello friends hope you are having fun. Atmega based garage door opening. The code for password based door lock security system using arduino keypad is given below.

How to design circuit of password based door lock system. Again if another person arrives it will ask to enter the password. You can simply copy paste the code using arduino ide. The simply compile it then finally upload it to the atmega328 microcontroller.

In this project i am going to design a simple automatic door lock system using 8051 89c51 89c52 microcontroller 16 2 lcd 4 4 numeric keypad and a digital lock. Electronic code locking system is extremely useful in protecting our precious possessions and can be installed anywhere with bit of engineering in it. Password based keypad door lock in this article a digitally secured lock based on password verification is explained the system uses a seven segment display array to show the password a matrix keypad to enter the numbers password and operates a relay to activate the solenoid valve for locking and unlocking purpose. This is an advanced door opening system compared to the above system.
