Is the moisture sensor build doc accurate

[mrhutchinsonmn]

I am attempting to set up a moisture sensor, using the diagram and included sketch (https://www.mysensors.org/build/moisture). The diagram shows pin 3 for data but the sketch references d6 and d7. I don't see any reference to pin 3 there. I am not clear why there are references to d6 and d7 when my sensor only has a single data pin.

@mrhutchinsonmn you're right that the description and the sketch don't add up. They definitely need some work.
