RFID Reader! Identify anything with RFID from credit cards to license plates

Hey guys today I just got an RFID Reader module from Parallax! I tried it out and made this program which identifies cards and other RFID products! All you need is a computer, an Arduino, a breadboard, and the Parallax RFID Reader Module! Please share your experiences, I am in wonder of what may have happened to you while building it or something like that! Thanks.

Step 1 The circuit!

This is a very simple circuit which only needs four wires! (besides the usb) Down below is a diagram!

hi i got the rfid going on my arduino uno. but i cant figure out how to make a led on pin 13 turn on when a specific card is read.also how wold i Chang the name of the card so when it reads a2r128 a1r120 a0r-1 a0r-1 a0r-1 a0r-1 a0r-1 a0r-1 a0r-1 a1r248 a4r128 a6r128 a10r120 a13r0 a17r120 a19r128 a18r0 a17r128 a16r128 a15r0 a14r120 a13r120 a12r120 a11r248 a10r128 a11r120 a16r128 a19r248 a23r0 a26r120 TAG: and change that to: joe hudy. and with that name "joe hudy" i cold put it on my lcd.

I'm publishing a newer version of this instructable soon, it is going to incorporate the card code comparing.

[simonfrfr]

You cannot change the name of the card because this is only a reader, but you can assign a name and value for the card. For Example lets say you want to have a vending Machine account, you can enable a card on the system when you buy it. You could set the name and when you scan it it goes into the system. Under the Name there could be a value which could be changed like subtracted when you spend money or added when you put money in the account.

i was wondering how can you add a display to this code? maybe one of the touch screen LCD's? i have one of those i wanted to view on that. and my
C++ is at a beginners hello world basically...

[simonfrfr]

Well can you please specify which LCD you are talking about?

[zer0nerz]

it says HY-tft320_262k under, it has a SD card slot also.

[simonfrfr]

can you give me the product page, then I should be able to help you, Thanks Simon

DB0-DB16 to pin D0-D13, pin A0-A1 of Arduino
RESET to A2
CS to A3
WR to A4
RS to A
this should take up most of the pins on the Arduino UNO, so you would need an Arduino Mega for this to function.

[zer0nerz]

i have uno and mega

[simonfrfr]

Ok then, you will need to edit the code then. You will need to use multi-serial on the mega and change the Enable port to 50. Or something like it.
Then programming the LCD is necessary. I will try to make a sample code for you of the RFID and everything when I get a chance. That should be soon

[zer0nerz]

thank you so much =)

[simonfrfr]

did you already buy this? I have something similar but I like it better.

[zer0nerz]

what did you have by the way?

[simonfrfr]

well I bought a few products for 4D systems and they work well with Arduino. I love their products. I am trying during my free time from school to work on your problem.

[zer0nerz]

I yes i have it in possession now. Was so curious what i can do with this thing.
