Password based door lock system using 8051 ppt.
One of the prominent features of these innovative lock systems is their simplicity and high efficiency.
User can change this password anytime he she wish using a keypad.
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.
Introduction password based door security system using microcontroller is used in.
If the password is wrong then door is remain closed and displays pwd is wrong on lcd.
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.
This controller requires a supply voltage of 5v dc.
Traditional lock systems using mechanical lock and key mechanism are being replaced by new advanced techniques of locking system.
This controller requires a supply voltage of 5v dc.
If the entered password is correct then the system opens the door by rotating door motor and displays the status of door on lcd.
These techniques are an integration of mechanical and electronic devices and highly intelligent.
This is the cpu central processing unit of our project.
How to design circuit of password based door lock system.
Password based door locking system.
Here an at89c52 microcontroller is used and it is an 8 bit controller.
We are going to use a.
