Got ya. I'd like to build a bare bones read and print sketch.
First thing to do is see what comes back from the module:
void parse()
{
while(rfid.available())
{
byte rfidVal = rfid.read();
Serial.println(rfidVal, DEC);
}
}
This will print every thing that the reader outputs. If this works, we can move on to reading the data properly, and then making use of the data.
