Password Based Door Locking System Using Arduino Ppt

This is a door lock security system made with arduino.

Password based door locking system using arduino ppt.

Objective increase the security level to prevent an unauthorized unlocking of the door. Lock the door by using password. 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.

So when the password is correct pin 11 is set high and pin 12 is set low. Password based door locking system project report pdf 16. Shown in video 3. Give the flexibility to the user to change or reset the password in case the user forgets that combination.

Just thought of making a password based door lock system in which you can enter the password via the keypad. 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. The code for password based door lock security system using arduino keypad is given below. To give user more secure yet cost efficient way of door locking system.

Password based door lock system using 8051 microcontroller ppt 15. You can simply copy paste the code using arduino ide. Password based door lock system using arduino 14. This block gives the entered code signals to the microcontroller.

5v input and outputs 12v to its output pins to which the actuator is connected. 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. It uses arduino nano to provide a keypad interface door lock for the front door. In countries like india such automatic systems are not cheap by any yardstick.

To open the door the user will have to first scan the right tag and then he will have to enter the correct password. Pins 11 and 12 are connected to the inputs of the l293d. 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. Again if another person arrives it will ask to enter the password.

It is a simple embedded system with input from the keyboard and the output being actuated accordingly. Hence the actuator is pulled inside and the door opens. This circuit allows activation of an electronic door lock only on entering the correct password. It was an interesting project which required beginner s level skill in programming and very easy to connect circuit.

The keypad is an input device that helps to enter a code to open the door. Rfid and keypad based door lock using arduino by aqib.
