How to connect Arduino and RFID
CNC G-Code Interpreter using Processing
plz send me rfid code at this firstname.lastname@example.org i need it urrgent...plz
Hi, Thanks for the kind response, Can we measure distance via signal strength? Or can you please suggest me any other module? I have MLX 90109 with DVK 90109 and EVB 90109
I don´t think it is possible to do that with this particular module.
Hi, This is really nice. Can we calculate distance also? if in case we would like to calculate distance as how much far or close the tag is with reader , is that possible?Regard'sHari

Just figured it out now how can i get the id part out of whats being read? I also noticed that sometimes im reading double of the same part of the code?
Send me your code and a pic or schematic of your conection
send me your code and a pic of your schematic
i have the same problem. please tell if someone have sorted out. - F-sidd142
I had the readers and they dont seem to be reading i have them hooked up the way you have it set up but how does your code work? there arent any comments throughout the code and i have been looking to use them for a school project. can you help? - lef11
i am able to work with arduino uno but unable to get it working on arduino mega.i used the code above and connected the rfid pin to arduino mega's digital pin 2.help...!! - F-sidd142
Hi,Ss you can see in the image below the number 000138297 inscribed is in DEC. Cinverting it to HEX give us this 00151B81. Probably the beginning "31" and the final "BE" should be a verification code.So the reading is OK, the problem is on the conversion from DEC to HEX.
Hello,Using your code to decode a keychain fob ID tag. The fob has the number "0001383297" inscribed. The code outputs "3100151B81BE". Boards are hooked up per your directions, using the same RFID receiver card and the Sparkfun UNO board. Any ideas on how to decode the output that matched the inscription? I have used a commercial USB RFID reader (it looks like a thumb drive) and it outputs the number inscribed on the fob.Thanks!
Do you know if using this approach you can connect more than one RFID reader to a single arduino?
Hello, how can i add more tags ? what i need to change in the code?thanks
Just a few quick questions: Which arduino board did you use for this project? Also, I see that pin one TX of the RFID sensor is being connected to digital pin two of the arduino board, is this digital pin two a special pin such as RX or is it a normal digital pin? Thank you for a great instructable!
