RFID DOOR ACCESS CONTROL WITH COUNTER

In this tutorial you will learn what RFID is, how it works and how to make an Arduino based RFID door Access Control with counter and you also see who last access . You can watch the following project video

Overview of RFID

RFID stands for Radio Frequency Identification and it is the concept of identification through radio frequency. It is a method of transmitting data via radio waves in magnetic fields wirelessl and without contact. This technology is used for automatic identification of, for example, goods, objects, and people. RFID offers an important platform for identification of objects, data collection and management of goods.

An RFID system consists of two main components, a transponder or a tag which is located on the object that we want to be identified, and a transceiver or a reader The RFID reader consist of a radio frequency module, a control unit and an antenna coil which generates high frequency electromagnetic field. On the other hand, the tag is usually a passive component, which consist of just an antenna and an electronic microchip, so when it gets near the electromagnetic field of the transceiver, due to induction, a voltage is generated in its antenna coil and this voltage serves as power for the microchip.

How to find out Tag Code

First you have to need Download RFID Library from GitHub Click Here
Connect RFID With Ardunio

Now you Have to need  upload the “DumpInfo”  from example 

Now if you run the Serial Monitor you can find RFID Tag code

In This project you have to need

Hardware

1. MFRC522 RFID Module
2. Servo Motor 
3. LCD Display 
4. Arduino Board
5. Breadboard and Jump Wires

Software

Ardunio
