The door is opened by motors which in turn are controlled by this security system.
Password based door locking system project ppt.
The keypad is scanned for pressed digits one by one.
As the program starts string enter password is displayed on the lcd.
Here an at89c52 microcontroller is used and it is an 8 bit controller.
Working of project as the program starts string enter password is displayed on lcd after the four digits are entered the user is prompted to confirm password if the passwords do not match a message is displayed to indicate wrong password again the keypad is scanned for pressed keys and corresponding digits are identified if all the four digits match with set password the lock output pin goes high the system gets locked if more than three attempts are made with wrong.
Password based door lock system using8051 microcontrollertraditional lock systems using mechanical lock and key mechanism are being replaced by newadvanced techniques of locking system.
Password based door lock system using 8051 microcontroller final report.
Description of the project.
Password based door lock system the aim of this project is to create a security system which asks for a password before opening the door and opens the door only if the password matches the programmed key.
The project is connected to the main supply 23.
Using keypad it enters a password to the system and if entered password is correct then door is open by motor which is used to rotate the handle of the door lock.
These techniques are an integration of mechanical andelectronic devices and highly intelligent.
In this video you can learn how to make a simple password based door lock system using arduino servo motor and 3 4 matrix.
In day to day life security of any object or place password based system plays a major role.
This project has considered about this and created a secure access for a door which needs a password to unlock the door.
The door security system will be displayed 24.
Confirm the password 26.
Enter the password 25.
Introduction the microcontroller based door locker is an access control system that allows only authorized persons to access a restricted area.
Now lock is activated enter the correct password to open the door with the display lock open 27.
Password based door lock system using 8051 microcontroller circuit design uses five major components a microcontroller an l293d motor driver a dc motor a 4 4 matrix keypad and a 16 2 lcd.
The system is fully controlled by the 8 bit microcontroller at89c2051 which has a 2kbytes of rom for the program memory the system has a keypad by which the password can be entered through it.
User can change this password anytime he she wish using a keypad.
P0 7 has been used as lock output pin of controller.
