I had a quick question concerning the Parallax RFID reader, I have been able to get the reader to work with various sketches found on the site, thanks to all that have contributed to the effort. But I seem to running into a hardware issue.
I won't post an code because it seems to effect every piece of code I have loaded, so I assume it is a hardware gremlin.
Seems as if when I tie the Sout on the reader to the Rx pin on the arduino I can no longer receive basic character input from my keyboard. As soon as I lift the wire from the Rx pin the program returns to working properly. I even tried disabling the reader via output pin 2, the only thing that works in lifting the wire from Rx.
It seems to me that if you tie into the Rx pin on the Arduino, it will no longer listen to any other serial information via USB from the pc.
Has anyone addressed this issue, or is the reason softwareSerial was created?
