The persons can go inside and locks the door.

Smart door lock using arduino.

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 lock the door. I have already posted an tutorial about the same project with bluetooth module you can refer it for any clarifications. 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.

This is a door lock security system made with arduino. Collecting the items required step 2. Smart bt door lock simple arduino project showcase by arun. If both passwords are correct then a servo motor connected to pin 6 of arduino opens the door.

I have rechecked the code many times. A switch is provided for opening the door from inside. Incase of emergency a third password is also provided by which any person outside can open the door. Similarly for unlocking we ll write low value to d0 and high value to d3.

Just thought of making a password based door lock system in which you can enter the password via the keypad. Smart bt door lock simple arduino this is a simple project made with arduino uno r3. This will signal the arduino to unlock the door. The aim is to control a door lock without keys but using a smart phone instead.

Smart bt door lock simple arduino gpl3. This is a simple project made with the arduino uno r3. The code for password based door lock security system using arduino keypad is given below. 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. The communication medium will be the internet wifi module esp8266. For locking we use the digitalmultiwrite method from library to write high value to d0 and low value to d3. The simply compile it then finally upload it to the atmega328 microcontroller.

Download the library for keypad h from below. You can simply copy paste the code using arduino ide.
