Quick one,
As I am awaiting delivery from a couple of max7219 chips I thought I would look at rfid, I did a little research and noticed sparkfun did one. But they charge quite a bit of money for one. I checked good o'ld eBay and found this http://www.ebay.co.uk/itm/RFID-13-56Mhz-Module-Tags-SPI-Interface-Read-Write-for-Arduino-UNO-R3-Mega-MCU-/170947354322?pt=UK_Computing_Other_Computing_Networking&hash=item27cd419ed2 its perfect price point. but I am not so good on the programming side and was wondering if there is a similar one that has a library so I can interface it with hopefully my computer! Thank you for reading and see you soon

Your ebay page links to Arduino sample code. What else do you expect?

I don't know the module and don't know if it works but you seldom get that much Arduino support on ebay.


Sorry frind,
My email was rushed yesterday. here is the link I mean to to send:
I would like to easily control or read the information. and the sample code is very hard for beginners. I was wondering if there were any libraries to simplify the process to start of. Thank you for your reply.

The sample code is a library although it doesn't come in that format. Just split the file up and place the setup() and loop() routines in a separate file and you have a library.

To start, just uncomment the Serial.println() in lines 186-196 and you get the serial number of every tag the reader get a hold of. What more do you need to start?


No promises... but at that price, I'd certainly give it a try, if I were you.

The following code... library-less... would probably need very little adapation, if any...


For the beginner, libraries are a mixed blessing. They have their place... but should be used in moderation!
