It's OK to make a copy of the playground article, but please put a reference in it to the playground.

OK, I'll only copy the overview for people starting out with this. The details and examples and updates will be seen through the Playground link.

I'd like to end up with something like this I did for the DS18B20 : http://arduino-info.wikispaces.com/Brick-Temperature-DS18B20

Here's my first pass: http://arduino-info.wikispaces.com/TemperatureHumidity PLEASE critique / comment!!

Thanks!
