Password Based Door Locking System Using 8051 Ppt

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.

Password based door locking system using 8051 ppt.

This system allows the user to unlock the device with a password they entered password equals with the password stored in the memory then the. User can change this password anytime he she wish using a keypad. In this way a simple door lock system can be implemented with the use of a microcontroller. Working of password based door locking system with 8051 when power supply is turned on a message enter your password is displayed on lcd.

If the person attempting to open the door enters a wrong password then the microcontroller switches the alarm for further course of action. The system compares the user password with the password stored in eeprom memory. Video of the project. If password does not match door remains closed and a message wrong password access denied is displayed on lcd.

If the code matches the predefined hard coded code lock will open up and user can enter the room. The main concept behind this project is a door latch opening using a password entered through the keypad. Again if another person arrives it will ask to enter the password. This is an advanced door opening system compared to the above system.

I2c bus protocol is used to interface eeprom memory to 8051 microcontroller. Atmega based garage door opening. User needs to enter the password using an application on android mobile. User have to enter the code.

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.

The microcontroller based door locker is an access control system that all electronic code lock with user defined password using 8051 microcontroller at89c51.

Predefined hard coded password is downloaded in the code. These techniques are an integration of mechanical and electronic devices and highly intelligent. All the processing s will be done by 8051 microcontroller. We type the password using keypad which is attached with the system.
