Rfid Based Door Lock System Using Arduino Uno

In this video you can learn how to make a simple password based door lock system using arduino servo motor and 3 4 matri.

Rfid based door lock system using arduino uno.

On scanning the wrong tag or on entering the wrong password the system will deny access. The connection with the arduino uno board is very simple. 3 x led s red green blue 3 x 220 ohm resistors. Arduino uno rfid based automatic door lock system using an arduino.

At first let s connect the power of both the reader and the display. The rfid tag consist of integrated circuit and an antenna integrated circuit is for the storage of the data and an antenna is for transmitting the data to the rfid reader module. In this post you are going to learn about how to build an rfid and keypad based door lock using arduino. Interfacing of rfid with arduino can be done by the following steps.

Arduino uno or any other arduino. So we decided to test a simple and cheap prototype to see if such a robust system could be developed using the tool of our choice arduino uno. In countries like india such automatic systems are not cheap by any yardstick. Working of arduino based rfid door lock the rfid system consists of two components.

Rfid is a non contact automatic identification technology that uses radio signals to identify track sort and detect a variety of objects including people vehicles goods and assets without the need for direct contact or line of sight contact as found. This is a simple arduino project. Since the display can also work at 3 3v we connect the vcc from both modules to the breadboards positive rail. There are many rfid readers are available in the market with 5v 9v and 12v.

But here a 12v rfid reader is used for an. Be careful the rfid reader must be connected to the 3 3v output of the arduino uno or it will be destroyed. This rfid based access control system is built around arduino uno board rfid reader module solenoid lock and a few other components. Rfid stands for radio frequency identification and it s a non contact technology that s broadly used in many areas such as personnel tracking access.

The components you are going to require for rfid based access control system using arduino are as follows. To open the door the user will have to first scan the right tag and then he will have to enter the correct password. In this tutorial we are going to learn how the mfrc255 rfid reader works and how it can be interfaced with arduino in a number of projects like the arduino based rfid door lock system. An rfid tag and a reader.
