/*************************************************************
This is the latest and likely final rev of my Smartphone Garage Door Opener sketch
using the Adafruit Feather Huzzah board and the Blynk framework. It's pretty robust 
and yells at you when you leave the garage door open too long. I hope it serves you well.
