Repeated Read and Write to/from RFID

Hi, I am designing a project which requires RFID tags to be read from, and preferably able to be written to more than once. I was going to buy the RFID components separately from the Arduino until I noticed that Arduino has its own RFID sets/boards.

Is there an Arduino set that will allow me to read and write to an RFID tag, and output the data that is read to a servo?

Thanks! If you need any further details, please ask as I am sure there are required details I have not specified (this will be my first time using Arduino). :slight_smile:

If you want to read and write data then you need to get a smart card type RFID system. The mifaire Classic card is is one such type, the readers can be cheap and use the SPI interface. There is no particular advantage in an own Arduino board.

Okay, thanks! And what did you mean by "There is no particular advantage in an own Arduino board"?

You mentioned that "until I noticed that Arduino has its own RFID sets/boards". It doesn't. There are RFID shields and RFID hardware that is usable by an Arduino. But, even if Arduino did sell RFID boards, there is no particular advantage in using one of them over any other RFID reader/writer.

Ah yes sorry, RFID shield is what I meant. I guess my question is really: What Arduino board would be most suitable for what I'm doing? Thanks for your help! It's probably tedious helping someone who has never used RFID or Arduino before lol

Well if you would tell us what you ARE doing then maybe we could help.

I would suggest the Kuman RFID kit on amazon. You'd have to look into the details, but it's made for learning RFID so it might suit your needs well. However, if we knew what your project is, we could help you much better.

Sorry, haha! For the project, I will be storing minute amounts of data onto RFID tags and reading back the data from them as well. When data is sent to an RFID tag, the data is based off of potentiometer states (positions). When data is read from an RFID tag, it will be used to move servos to a certain position until their corresponding potentiometers reach the required position.

The each servo will be mechanically linked to its own potentiometer - the potentiometers will be acting as position sensors.

(Think of the whole system as a way of saving user-specific settings to a user’s RFID tag)

Hope this helps :slight_smile:

This one would do:-

Thanks, Grumpy_Mike!

Would this be it here?

Yes that looks like it. The ones I got had a blue PCB though and were a bit cheaper. I got three readers for just less than £10.

This one is even cheaper.

Like getting into a car and scanning you card and the steering wheel and seat all automatically move to your custom position.
Tom... :slight_smile:

In case you need a demo of the Mifare RFID read/write using an Arduino I have a YouTube video #34 that may be of interest. It's pretty straightforward to do once you see how it's done.

@Mike Okay, awesome thx!

@Tom ...yes O_o

@Ralph Thanks! I will probably end up looking at that :stuck_out_tongue:
EDIT: Subbed, Ralph! Nice channel! :stuck_out_tongue:

Grumpy_Mike, I'm assuming the MIFARE that I bought (https://www.amazon.ca/MIFARE-ANTENNA-READER-PROXIMITY-MODULE/dp/B01EH5O1FI/ref=sr_1_2?ie=UTF8&qid=1464903834&sr=8-2&keywords=rc522) would be instead of the RFIDuino? I read that the RFIDuino is to be plugged into an Arduino board, which Arduino board would you recommend I use to plug the MIFARE into?

Every Arduino which is capable of SPI communication is fine. All of them are.

Okay, awesome :stuck_out_tongue:
So if I were to get the UNO, for example, I would be able to use it with the MIFARE RC522? Would I also be able to control 3 servos and receive input from 3 potentiometers?

Triple yes.

Good to hear! Thanks!
