Got myself a new computer and needed to recompile this project; when I did that I used Arduino version 1.8.15 rather than 1.8.14 as I had in the past.  Oddly I started running into memory issues, so I reverted to 1.18.14 for the build.  In the process, I also made some changes to the source available on Github for better memory efficiency. 

I am also having some Bluetooth issues on my new computer, so if you are trying out this project I'd appreciate your feedback.
