Password Based Door Lock System

You can simply copy paste the code using arduino ide.

Password based door lock system.

Password based door open system using lpc2148 introduction in the present scenario of the world security is a major concern for all and the security problem is being faced by every person. Complete video tutorial. In this video you can learn how to make a simple password based door lock system using arduino servo motor and 3 4 matrix. Here at89c52 microcontroller is used and it is an 8 bit controller.

Traditional lock systems using mechanical lock and key mechanism are being replaced by new advanced techniques of locking system. The code for password based door lock security system using arduino keypad is given below. 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. Password based door lock system circuit diagram working process require components code step by step connections explanation.

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. Electronic code lock system circuit design. Password based door lock system using 8051 microcontroller is a simple project where a secure password will act as a door unlocking system. The simply compile it then finally upload it to the atmega328 microcontroller.

Old fashioned lock systems use mechanical locking and these can be replaced by new advanced techniques of locking systems. These methods are a combination of mechanical and electronic devices. Password detector can be used to automate the door locking process so the user need not to carry the door lock keys along with him he can just remember the password and use it later to open. This controller requires a supply voltage of 5v dc.

Keeping this problem in mind we are working on a project on. 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.
