Smart Door Lock System Project Using Arduino

As thefts are increasing day by day security is becoming a major concern nowadays. The aim is to control a door lock without keys and using a smartphone to accomplish this. In this project we want to make an arduino based system that helps you to make a login section for a door by wifi and solenoid lock.

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.

Smart door lock system project using arduino.

In this project we are going to build a biometric lock using arduino nano with bluetooth module solenoid lock and android phone. 62 is xor value for 02 xor 00 xor 10 xor 7d xor 0d. We don t use keypad or complicated mechanical elements and these are advantages of this system. In the below code the rfid tag number are stored in the char tag.

Password based security system using arduino keypad. Hence number on the card is 0001080589 code and explanation. So a digital code lock can secure your home or locker easily. Make sure you get a fingerprint sensor that works with the arduino through the serial communication.

We just stick a qr code to the door and the allowed people can scan it to see the login page and enter their password. Here nodemcu will act as the main controller and connect the user to the door lock system using the internet. Here we are also building a similar wi fi door lock which can be controlled from the smartphone. For this project we will use the softwareserial library in the code.

180088f889e1 is my rfid tag number stored in the microchip of the transponder the length of the tag number is 12 we have defined. Wifi smart door simplest method this is a simple project made with the arduino uno r3. The complete rfid door lock arduino code is given at the end of this project. So in this project we are going to make an iot based door lock system using nodemcu solenoid lock and adafruit io.

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. Apart from hardware a mobile application is also used to scan and verify the fingerprint and send the confirmation id to arduino through bluetooth. In this project we will learn how to make the password based security system using arduino keypad. Smart bt door lock simple arduino.

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. Some examples are pir based security system rfid based security system digital lock system bio matrix systems electronics code lock.
