Introduction: ARDUINO _RFID _LCD (rfid Security System)
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
Step 1: WATCH THE VIDEO
Step 2: THINGS NEEDED
To make the this project you need these following project
1.Arduino uno (or clone)
8.Copper dot PCB
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
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
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.
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
