 * Libraries:
 * Timer library was created by Simon Monk as modified by JChristensen  https://github.com/JChristensen/Timer.  Note: if you
 * download the library from the source, you must rename the zip file to "Timer" before importing into the Arduino IDE.
 * 
 * An enhanced SmartThings Library was created by  Dan G Ogorchock & Daniel J Ogorchock and their version is required for this implementation.
 * Their enhanced library can found at:
 * https://github.com/DanielOgorchock/ST_Anything/tree/master/Arduino/libraries/SmartThings
 *
 * SoftwareSerial library was default library provided with Arduino IDE
