Smart Door Lock System Project Using Arduino

Smart bt door lock simple arduino project showcase by arun.

Smart door lock system project using arduino.

Similarly for unlocking we ll write low value to d0 and high value to d3. This is a simple project made with the arduino uno r3. The communication medium will be the internet wifi module esp8266. The simply compile it then finally upload it to the atmega328 microcontroller.

This will signal the arduino to unlock the door. In this post let us build a secret knock detecting door lock using arduino which can detect the pattern of your knocks at the door and will only open the lock if the knocking pattern matches with the correct pattern. The code for password based door lock security system using arduino keypad is given below. This will signal the arduino to lock the door.

The aim is to control a door lock without keys but using a smart phone instead. This is a simple project made with arduino uno r3. Make sure you get a fingerprint sensor that works with the arduino through the serial communication. The default pins for serial communication on the arduino uno are pin 0 rxd and pin 1 txd of the board but we are going to use other pins for serial communication.

Just thought of making a password based door lock system in which you can enter the password via the keypad. For the proper working demo check the video at the end. I have already posted an tutorial about the same project with bluetooth module you can refer it for any clarifications. Probably you have seen smart locks for doors that have a keypad or use a fingerprint to set the door lock or unlock.

Download the library for keypad h from below. We ll discuss the arduino code and circuit design later in this tutorial. The aim is to control a door lock without keys and using a smartphone to accomplish this. We don t use keypad or complicated mechanical elements and these are advantages of this system.

It was an interesting project which required beginner s level skill in programming and very easy to connect circuit.

You can simply copy paste the code using arduino ide.
