In this project we will learn how to make password based door lock security system using arduino keypad.
Password based door locking system using arduino uno.
So a digital code lock can secure your home or locker easily.
The password based door lock system allows only authorized persons to access the restricted areas.
The code for password based door lock security system using arduino keypad is given below.
As thefts are increasing day by day security is becoming a major concern nowadays.
It will open your door only when the right password is entered.
The simply compile it then finally upload it to the atmega328 microcontroller.
Old fashioned lock systems use mechanical locking and these can be replaced by new advanced techniques of locking systems.
A 4 4 or 4 3 keypad can be used to enter the desired password.
Password based door lock system using arduino uno is a simple project where a secure password will act as a door unlocking system.
About the 4 4 keypad.
The entire project is controlled by using the arduino.
