RDM3600 RFID COMPONENT

These issues are often causes by the simple things.

Have you tried swapping the TX/RX pins around?

Can you take a photo or sketch out your connections between the RFID reader and the Arduino.

Here is a picture. Just power, ground, and a jumper to pin 3 on the Arduino Uno and the antenna that came with the RDM3600. I modified the code to change the RX and TX pins to 3 and 4:

#include <SoftwareSerial.h>

SoftwareSerial RFID(3, 4);

int i;

void setup()

{

  RFID.begin(9600);

  Serial.begin(9600);

  Serial.println("ready");

}

void loop()

{

  if (RFID.available() > 0)

  {

    i=RFID.read();

    Serial.print(i, DEC);

    Serial.println(" next");

     }

  }

Thank you

When I link pin 3 and pin 0 I can send a value via the serial monitor that appears on the the monitor. What does this mean?

Ok. Have spent some time playing with this...Try changing your SoftwareSerial pins from 3&4 to 10&11. Connect your RFID reader to pin 10.

It is likely due the limitations outlined on this page: Arduino - SoftwareSerial

Still no luck...

Ok. I tested the code on an Arduino Leonardo, With a USB-232Serial(TTL) adaptor connected to pin 10. When I copied you code over and changed 3,4 to 10,11 in the SoftwareSerial declaration I received the ascii code number followed by the word "next".

For example pressing 1 resulted in "49 next". I used a cable like this http://uk.farnell.com/ftdi/ttl-232r-3v3/cable-usb-to-ttl-level-serial/dp/1329311 and a separate Serial Terminal program to send the data to the Arduino.

Here is the code I was using:

#include <SoftwareSerial.h>

SoftwareSerial RFID(10, 11);

int i;

void setup() {
  RFID.begin(9600);
  Serial.begin(9600);
  Serial.println("ready");
}

void loop() {
  if (RFID.available() > 0) {
    i=RFID.read();
    Serial.print(i, DEC);
    Serial.println(" next");
  }
}

I think my problem is I'm using RFID tags that operate at a higher frequency than the 125kHz that the reader uses.

I ordered some new tags, I will keep you posted.

Are you trying to use Mifare tags? If so they operate on 13.56MHz.

I've just purchased one of these modules, so I should have a better idea whats going on in a couple of days.

I was using a WMATA SmartTrip card and some tags I found on Amazon:

I chose the RDM3600 because I can modify the antenna to increase the read range.
