To give user more secure yet cost efficient way of door locking system.
Password based door locking system using arduino ppt.
This is a door lock security system made with arduino.
So when the password is correct pin 11 is set high and pin 12 is set low.
Objective increase the security level to prevent an unauthorized unlocking of the door.
So we decided to test a simple and cheap prototype to see if such a robust system could be developed using the tool of our choice arduino uno.
The keypad is an input device that helps to enter a code to open the door.
It is a simple embedded system with input from the keyboard and the output being actuated accordingly.
This system demonstrates a password based door lock system using 8051 microcontroller wherein once the correct code or password is entered the door is opened and the concerned person is allowed access to the secured area.
The code for password based door lock security system using arduino keypad is given below.
You can simply copy paste the code using arduino ide.
It was an interesting project which required beginner s level skill in programming and very easy to connect circuit.
Again if another person arrives it will ask to enter the password.
Shown in video 3.
To open the door the user will have to first scan the right tag and then he will have to enter the correct password.
It uses arduino nano to provide a keypad interface door lock for the front door.
Hence the actuator is pulled inside and the door opens.
5v input and outputs 12v to its output pins to which the actuator is connected.

Download the library for keypad h from below.
It takes inputs from the arduino i e.
Just thought of making a password based door lock system in which you can enter the password via the keypad.
This block gives the entered code signals to the microcontroller.
The simply compile it then finally upload it to the atmega328 microcontroller.
It is a keyless system where you can use your own personal code to enter your home with just a few simple pushes of some buttons.
Pins 11 and 12 are connected to the inputs of the l293d.
Password based door lock system using arduino 14.
In countries like india such automatic systems are not cheap by any yardstick.
Give the flexibility to the user to change or reset the password in case the user forgets that combination.
Lock the door by using password.
