The aim is to control a door lock without keys but using a smart phone instead.

Smart door lock using arduino.

Smart bt door lock simple arduino project showcase by arun. It was an interesting project which required beginner s level skill in programming and very easy to connect circuit. Smart bt door lock simple arduino gpl3. Just thought of making a password based door lock system in which you can enter the password via the keypad.

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. You are given a card and you just need to put it in front of a rfid reader box and the lock gets unlocked with a beep and a blink of led. Incase of emergency a third password is also provided by which any person outside can open the door.

This is a door lock security system made with arduino. I have rechecked the code many times. This will signal the arduino to unlock the door. Working of the project.

For locking we use the digitalmultiwrite method from library to write high value to d0 and low value to d3. The persons can go inside and locks the door. Similarly for unlocking we ll write low value to d0 and high value to d3. The communication medium will be the internet wifi module esp8266.

If both passwords are correct then a servo motor connected to pin 6 of arduino opens the door. This is a simple project made with arduino uno r3. A switch is provided for opening the door from inside. This is a simple project made with the arduino uno r3.

This will signal the arduino to lock the door. Arduino rfid door lock hardware project setup you have seen rfid door lock mechanism in some hotels and other places where you don t need a key to unlock the room. Smart bt door lock simple arduino this is a simple project made with arduino uno r3. Download the library for keypad h from below.

The aim is to control a door lock without keys but using a smart phone instead. The aim is to control a door lock without keys and using a smartphone to accomplish this.
