Password Based Door Lock System Using 8051 Microcontroller Program Code

The microcontroller has a program.

Password based door lock system using 8051 microcontroller program code.

Wherein once the correct code or password. 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. If the code matches the predefined hard coded code lock will open up and user can enter the room. Predefined hard coded password is downloaded in the code.

Here 4 4 keypad is used to enter the password. The entered password is compared with the predefined password. Again if another person arrives it will ask to enter the password. This system demonstrates a password based door lock system using 8051 microcontroller wherein once the correct code or password is entered the door is opened and the concerned person is allowed access to the secured area.

It s a digital door lock system based on 8051 controller accept password from user to open the door connected with dc motor. All the messages to input password access granted access denied will be popping up on 16 2 lcd on the right time. This output load can be a motor or a lamp or any other mechanical electrical load here we developed an. These techniques are an integration of mechanical and electronic devices and highly intelligent.

Electronic code lock system using 8051 microcontroller. A numeric password is hard coded in the 8051 microcontroller code. We type the password using keypad which is attached with the system. If it is correct password the system opens the door by rotating door motor and displays the status of door on lcd.

Working of password based door locking system with 8051 when power supply is turned on a message enter your password is displayed on lcd. For code and design log on to h. Design and implementation of embedded password based security door lock system using 8051 microcontroller. The main component in the circuit is 8051 microcontroller.

User have to enter the code. If password does not match door remains closed and a message wrong password access denied is displayed on lcd. Such an automatic lock system consists of electronic control assembly using rfid for authentication which controls the output load through a password and otp.
