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