 Found some incompatiablies with some other libraries (specifically some Adafruit Display Libraries). Forced all words to upper case. This will break previous sketches, but is easy to fix with search and replace.  
   ** As a side note, I had considered making all the words upper case early in  development. And decided that just adding the underscore would solve some problems.  Which it did - but it created other problems. **

+A script for a talking thermometer and hygrometer. 
+
+Build for the "Little Buddy Talker" device developed by Patrick Thomas Mitchell
+http://www.engineeringshock.com/
+
+Matt Ganis script was modified and adapted to the April 2018 version of the Word100 libray by Dr. H, 
+and combined with the Si7021 from Adafruit.
