Adding Sensors to an Arduino Data Logger

This adds to the set for beginners that I’ve been working on for my teacher friends. There are so many different kinds of sensors, that there is necessarily a lot missing from that post (like async serial..). So Adding Sensors (part 2) will follow in the new year when I can grab the time.
