Password Based Door Lock System Using 8051 Microcontroller

Our digital code lock project is a simple electronic number lock system or an electronic combination lock using 8051 which has a preset 5 digit password stored inside the program the system collects 5 digit user input compares the user input with the preset password inside program and if the user input and stored password matches access will be granted by opening the door with the help of relay for a few seconds and closing it automatically after stipulated time.

Password based door lock system using 8051 microcontroller.

In this project 4 3 keypad is used to enter the password. If password does not match door remains closed and a message wrong password access denied is displayed on lcd. The microcontroller based door locker is an access control system that allows only authorized person to access a restricted area the system is fully controlled by the 8 bit microcontroller 8051 which has a 2kbytes of rom for the program memory. Principle behind the circuit.
