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