In the following project we are going to make a rfid card reader by using the arduino uno and a rfid card reader.
the following project can do a lot of things such as reading a tag adding of the tag and also the deleting of the tag

Teacher Notes

Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.

Step 1: WATCH THE VIDEO

Step 2: THINGS NEEDED

To make the this project you need these following project

1.Arduino uno (or clone)

2.LCD(16x2)

3.RFID reader

4.RFID tags

5.LED (RED,GREEN,YELLOW)

6.Potentiometer(1k)

7.Bread Board

8.Copper dot PCB

9.Jumper Wires

10.Male and Female Header pins

Step 3: CIRCUIT CONSTRUCTION

Follow the given schamatic to make the PROJECT work

the connections to connect the RFID reader is given as

ARDUINO UNO RFID

+5V-------------------------------->+5V

GND------------------------------->GND

6------------------------------------->TX

FOR THE LCD TO WORK YOU NEED TO USE THE LIQUID CRYSTAL LIBRARY WHICH HAS BEEN SHOWN IN THE NEXT STEP

THE THREE LED'S ARE USED TO INDICATE THE CURRENT STATE OF THE READER

RED>>ACCESS DENIED INDICATION

GREEN>>ACCESS GRANTED INDICATION

YELLOW>>WHILE ADDING AND DELETING THE TAG

Step 4: ADDING THE LIBRARY TO ARDUINO IDE

To make the code work in the arduino we need to add or import the arduino library .In this project we are going to use two main library

1.liquid crystal library

2.wire.h

these library are preinstalled in the arduino ide but if not you can download the files from lthe following links

liquid crystall library is basically used to connect the the lcd to the arduino

wire.h is the library which will convert the normal digital outputs of the arduino into a serial port and with the help of this we are going to create another port to communicate with the RFID reader

To import the librarys you need to download the following zip file then extract it

then we are going to move them into the arduino / library folder.

https://github.com/esp8266/Arduino/blob/master/lib...

Step 5: CODING PART

AFTER THE LIBRARY'S ARE INSTALLED WE ARE GOING TO UPLOAD THE CODE TO THE ARDUINO

for that you need to download the following file to the arduino using the arduino ide and that's it!!!

    hi.some question easy..

    1)where can buy this model Rfid reader and what kind (khz) (name)

    2)where can buy for this model rfid tags (name)

    3) where can buy rfid cards for this model (name)

    if you can please send me the info thanks for your time..

    Thanks, I was looking for this.

    This is surely a cool project. I am thinking to apply this notion in my Iron Man Suit. (The Helmet). Check It out at http://www.bgbasicscience.blogspot.com
