Password Based Door Lock System (using 8051 Micro-controller)
Traditional lock systems using the mechanical lock and the key mechanism are being replaced by the new advanced locking system techniques. These techniques are an integration of mechanical and electronic devices and highly intelligent. One of the prominent features of these innovative locking systems is their simplicity and high efficiency.
Principle Behind the Circuit:
The main component of the circuit is the 8051 controller. In this project the 4 × 3 keypad is used to enter the password. The entered password is compared to the default password.
If the password entered is correct, the system opens the door by turning the door motor and shows the status of the door on the LCD. If the password is incorrect, the door will remain closed and "pwd is wrong" appears on the LCD.
