Again if another person arrives it will ask to enter the password.
Password based door locking system using arduino ppt.
Just thought of making a password based door lock system in which you can enter the password via the keypad.
It takes inputs from the arduino i e.
To give user more secure yet cost efficient way of door locking system.
In countries like india such automatic systems are not cheap by any yardstick.
It is a simple embedded system with input from the keyboard and the output being actuated accordingly.
The simply compile it then 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.
When we see sophisticated door management system s the price tag struck immediately along with the utility of course.
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.
This circuit allows activation of an electronic door lock only on entering the correct password.
This is a door lock security system made with arduino.
To open the door the user will have to first scan the right tag and then he will have to enter the correct password.
So when the password is correct pin 11 is set high and pin 12 is set low.
This block gives the entered code signals to the microcontroller.
Pins 11 and 12 are connected to the inputs of the l293d.
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.
You can simply copy paste the code using arduino ide.
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.
Hence the actuator is pulled inside and the door opens.
The keypad is an input device that helps to enter a code to open the door.
Password based door lock system using arduino 14.
Rfid and keypad based door lock using arduino by aqib.
Shown in video 3.
Objective increase the security level to prevent an unauthorized unlocking of the door.
It uses arduino nano to provide a keypad interface door lock for the front door.
Password based door locking system the operation of this system can be described by the above block diagram which consists of blocks as keypad a buzzer an lcd a motor driver and a stepper motor.
Download the library for keypad h from below.
5v input and outputs 12v to its output pins to which the actuator is connected.
Lock the door by using password.
