Password based door lock system using 8051 microcontroller traditional lock systems using mechanical lock and key mechanism are being replaced by new advanced techniques of locking system.
Password based door locking system using 8051 ppt.
In this way a simple door lock system can be implemented with the use of a microcontroller.
In this project i am going to design a simple automatic door lock system using 8051 89c51 89c52 microcontroller 16 2 lcd 4 4 numeric keypad and a digital lock.
I2c bus protocol is used to interface eeprom memory to 8051 microcontroller.
User have to enter the code.
Predefined hard coded password is downloaded in the code.
Atmega based garage door opening.
If the person attempting to open the door enters a wrong password then the microcontroller switches the alarm for further course of action.
This is an advanced door opening system compared to the above system.
We type the password using keypad which is attached with the system.
In our diy digital lock system 8051 89c51 89c52 is our intelligent unit.
It is a simple embedded system with input from the keyboard and the output being actuated accordingly.
If the code matches the predefined hard coded code lock will open up and user can enter the room.
All the processing s will be done by 8051 microcontroller.

If password does not match door remains closed and a message wrong password access denied is displayed on lcd.
Password based door locking system.
The system compares the user password with the password stored in eeprom memory.
Password based door lock system using 8051 microcontroller circuit design uses five major components a microcontroller l293d motor driver a dc motor a 4ã 4 lcd are connected to p3 0 gnd and p3 2 pins respectively.
These techniques are an integration of mechanical and electronic devices and highly intelligent.
Again if another person arrives it will ask to enter the password.
The microcontroller based door locker is an access control system that all electronic code lock with user defined password using 8051 microcontroller at89c51.
The main concept behind this project is a door latch opening using a password entered through the keypad.
User needs to enter the password using an application on android mobile.
