Interfacing the arduino with the parallax RFID reader?
Here is one that I found on the arduino playground:
I couldn't paste the code, because when I did it just went on one line, but the program I looked is the first one.
The questions I have are:
char code ---- what does the 10 mean?
Also how does the program read each byte individually, and then combine them into the whole byte string for the rfid tag.
I am just learning about using serial with the arduino so not much in the program made sense to me and the programs didn't say how they worked.
Thanks in advance!
