I've bought a RFID module for my Arduino Leonardo. I have made an code that waits for an input of RDM630 (RFID module) by the serial port. However, when I passed the card by the antenna, the module's led blinked (saying that had occured a reading), but the Arduino's RX led didnt blink, and my code hasn't worked (It was supposed to write the card number on the serial monitor).
To check if the module was sending data for by it's TX pin, I connected a led on this port (that is active low), and the led that was normally on, oscillated when I passed the card, what I believe be the data sending.
I tried other people codes, some of them using virtual serial ports implemented in other digital pins (e.g. 6 e 7), but i got no result again...
I believe the problem is at the data recieving by the Arduino, once I tested the data sending of the module (at least, is what i think).
Has someone ever faced a problem like this before? Does the serial communication have to be initialized in some other way that is not Serial.begin(baudrate)?
Thank you very much!
