Password Based Door Lock System Using Pic18 Microcontroller

This is an advanced door opening system compared to the above system.

Password based door lock system using pic18 microcontroller.

This controller requires a supply voltage of 5v dc. Electronic code locking system is extremely useful in protecting our precious possessions and can be installed anywhere with bit of engineering in it. Again if another person arrives it will ask to enter the password. We all know about electronic door locks as we have seen them in many homes.

If the person attempting to open the door enters a wrong password then the microcontroller switches the alarm for further course of action. 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. 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.

You can simply copy paste the code using arduino ide. In electronic door locks there s some password which is only known to some persons. Hello friends hope you are having fun. In our diy digital lock system 8051 89c51 89c52 is our intelligent unit.

Atmega based garage door opening. 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. 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. The simply compile it then finally upload it to the atmega328 microcontroller.

This controller requires a supply voltage of 5v dc. But we are going for electronic locks made by any company when you can make one by your own. How to design circuit of password based door lock system. In this way a simple door lock system can be implemented with the use of a microcontroller.

Electronic code lock system circuit design. Today i am going to share two types of electronic door locks design using pic microcontroller and simulated in proteus isis software. The code for password based door lock security system using arduino keypad is given below. Here at89c52 microcontroller is used and it is an 8 bit controller.
