The password based door lock system allows only authorized persons to access the restricted areas.
The entire project is controlled by using the arduino.
About the 4 4 keypad.
It was an interesting project which required beginner s level skill in programming and very easy to connect circuit.
Download the library for keypad h from below.
Just thought of making a password based door lock system in which you can enter the password via the keypad.
The default password stored in it will be 1234.
On scanning the right tag and on entering the right password it will send us a confirmation message that the door has opened.
