The code for password based door lock security system using arduino keypad is given below.

Smart door lock using arduino.

Similarly for unlocking we ll write low value to d0 and high value to d3. The aim is to control a door lock without keys and using a smartphone to accomplish this. It was an interesting project which required beginner s level skill in programming and very easy to connect circuit. Just thought of making a password based door lock system in which you can enter the password via the keypad.

This is a simple project made with arduino uno r3. 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. Download the library for keypad h from below. The simply compile it then finally upload it to the atmega328 microcontroller.

I have rechecked the code many times. I have already posted an tutorial about the same project with bluetooth module you can refer it for any clarifications. If both passwords are correct then a servo motor connected to pin 6 of arduino opens the door. 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 the arduino uno r3. Incase of emergency a third password is also provided by which any person outside can open the door. A switch is provided for opening the door from inside.

Collecting the items required step 2. Working of the project. The persons can go inside and locks the door. You can simply copy paste the code using arduino ide.

Smart bt door lock simple arduino this is a simple project made with arduino uno r3. 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. This will signal the arduino to unlock the door. For locking we use the digitalmultiwrite method from library to write high value to d0 and low value to d3.
