Questions for CrossRoads:

1.  What kind of pullup resistor should I purchase?

2.  Exactly which pins on the Ardunio Uno / SparkFun Protoboard should I attach the wire too?  Where should I place the LED?  How should I wire it?  I don't really understand. 

I'm a total noob when it comes to this sort of stuff (I've mainly been working with HandyBoard / CBC, where all of the sensors and motors fit nicely into predefined slots and you don't have to worry about anything on the electronics side). 



1. None. Use the internal pullup:
pinMode (pinx, INPUT);
digitalWrite(pinX, HIGH);  << this connects the internal pullup for pinX

2.  Hmm. Okay, go back and do some of the Learning tutorials. Specifically Blink & Button.
