Resistor needed? #5

Is the pull-up resistor actually needed? The web says that the NGC controller has a 745 ohm pull-up already.

huh, maybe not. I had assumed that either the controller or console side was responsible for pulling the data line high, and so the arduino would have that responsibility for one side of the connection (either console-arduino, or arduino-controller). I'm not sure I tried it without.

It's interesting. I just tried it without the external resistor in one of my projects and it didn't work well (it connected once or twice but unreliably and disconnected).
