RDM6300 RFID Reader - No readings

Other Hardware Sensors
1

I am following this tutorial

I have also tried this tutorial

My wiring is correct - I thought maybe that my reader was broken so I bought another one, but it still did'nt work.

For the mschoeffler tutorial all I get in my serial monitor is this line

Serial.println("INIT DONE");

for the instructable tutorial I never get anything to my serial monitor.

I am plugged directly into my USB port for the power source.
I usually have the TX on the reader plugged into digital 6 on the ArduinoUno (and adjust the code if needed) I have the 5v power and ground plugged directly the Arduino Uno.

My serial monitor is set to 9600

I am using these RFID tags

I have also tried the RFID tag associated with this product

As a note I can get the RC522 RFID reader to work with both kinds of tags, but don't want to use it in my project because of size constraints.

Did you note the vast difference in operating frequencies of the two devices?

Ahhh - okay - ya that makes sense I think.

the RDM6300 is 125Mhz
The RC522 is 13.25Mhz

I would then assume the tags I have are for 13.25Mhz

I will look around to see if I can find sticky 125Mhz tags, any suggestions

That's 125kHz, not mHz, which in in the aircraft communications frequency band and is a no-no!

Yup - trying to reply with 5 kids circling around :slight_smile: - My quick search is not showing me the kind of tags that I want to use though... I am trying to tag some hot wheel cars. Have you seen any in the world that would work for a use case like that? I am trying to use 4 of these readers (one for each lane on a track) The RC522 will take up to much space on the Arduino otherwise I could switch to that.
