Running a code example from the Piette DHT library from October 2014.

This is a new unit from SMAKN without any pre-soldered stuff. I took @ScruffR and @Moors7 's advice and soldered the headers on, but I’m still getting -7.000000. Pretty sure I have a 10k resistor on there (its hard to tell, but its in #2, pulling signal up to 3.3v). Wired like these here.

Halp?
