Good evening, 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…

Problems using serial port (TX and RX)
