This controller requires a supply voltage of 5v dc.
Password based door lock system using 8051 ppt.
Traditional lock systems using mechanical lock and key mechanism are being replaced by new advanced techniques of locking system.
Password based door locking system.
This controller requires a supply voltage of 5v dc.
Circuit diagram of password based door lock system using 8051 microcontroller.
The main concept behind this project is a door latch opening using a password entered through the keypad.
One of the prominent features of these innovative lock systems is their simplicity and high efficiency.
Video of the project.
We are going to use a.
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.
If the password is wrong then door is remain closed and displays pwd is wrong on lcd.
Here at89c51 microcontroller is used and it is an 8 bit controller.
User can change this password anytime he she wish using a keypad.
This is the cpu central processing unit of our project.
Here an at89c52 microcontroller is used and it is an 8 bit controller.
If the entered password is correct then the system opens the door by rotating door motor and displays the status of door on lcd.
