SainSmart 1.8 LCD / DHT-22 Temp / Humidity

I now have a DHT-22 Temperature and humidity module matched up with the SainSmart 1.8 TFT LCD. The tricky part of this project was converting floats to strings for the display. If you don't need decimal point precision, you may not need this function, but it's in there.

UPDATE: Added our SpeakEasy Text-To-Speech Shield, for voice output of the data, and relay activation for HVAC equipment.

The DHT-22 connections and the SainSmart LCD connections are in the code.
