You can simply copy paste the code using arduino ide.
Keypad based door lock system using arduino.
About the 4 4 keypad.
Download the library for keypad h from below.
In this project we will learn how to make password based door lock security system using arduino keypad.
It will open your door only when the right password is entered.
The code for password based door lock security system using arduino keypad is given below.
First of all we start from the brain of this project which is the arduino uno board.
So a digital code lock can secure your home or locker easily.
The entire project is controlled by using the arduino.
After you learned that procejt you can use that for your own room door or your wardrobe drawer even you can make combination safe.
Well i have used 4x4 keypad for this project but you can use different models but do not forget to change some parts in the code.
The complete circuit diagram for our arduino based digital keypad door lock project is shown below.
On scanning the right tag and on entering the right password it will send us a confirmation message that the door has.
You can halt the.
The arduino board is connected to an lcd and a servo motor.
The password based door lock system allows only authorized persons to access the restricted areas.
The simply compile it then finally upload it to the atmega328 microcontroller.
Working of rfid and keypad based door lock and alert system using arduino on scanning the wrong tag or on entering the wrong password it will send us an alert.
Hello dear friends in this project i have tried to explain how to built a door lock security system with an arduino and keypad.
