The setup is as shown below we have only added leds to show the state of the lock.
Password based door lock system using arduino and keypad.
On scanning the right tag and on entering the right password it will send us a confirmation message that the door has opened.
In this project we will learn how to make password based door lock security system using arduino keypad.
We have used eeprom in the arduino to store the password in it.
The entire project is controlled by using the arduino.
Download the library for keypad h from below.
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.
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.
Password security lock system using arduino keypad program code.
The password based door lock system allows only authorized persons to access the restricted areas.
You can easily copy and paste the code using the arduino ide.
The code for password based door lock security system using arduino keypad is given below.
The default password stored in it will be 1234.
Just compile it and finally upload it to the atmega328 microcontroller.
It was an interesting project which required beginner s level skill in programming and very easy to connect circuit.
So a digital code lock can secure your home or locker easily.
A 4 4 or 4 3 keypad can be used to enter the desired password.
About the 4 4 keypad.
The code is provided for a password security lock system using arduino keypad project.
The simply compile it then finally upload it to the atmega328 microcontroller.
