| Information is passed back & forth between the computer and Arduino by, essentially, setting a pin high or low. Just like we used that technique to turn an LED on and off, we can also send data. One side sets the pin and the other reads it. It's a little like [[http://en.wikipedia.org/wiki/Morse_code|Morse code]], where you can use //dits// and //dahs// to send messages by [[http://en.wikipedia.org/wiki/Telegram|telegram.]] In this case, instead of a long cable, its only a few feet. | Information is passed back & forth between the computer and Arduino by, essentially, setting a pin high or low.

| (Now, people who are all geeked-out will probably get angry at this point because I'm simplifying things. Well guess what, its an Arduino tutorial, not a OSI Physical Network Architecture tutorial.) | (Now, people who are all geeked-out will probably get angry at this point because I'm simplifying things.
