+///   Arduino SmartThings Ethernet WiFiEsp On/Off with LED Example 
+///
+///   Revised by Dan Ogorchock on 2017-02-20 to work with new "SmartThings v2.0" Library
+///
+///   Notes: The Arduino MEGA 2560 communicates via Serial1 to the ESP-01 WiFi board 
+///          to your home network router, then to the ST Hub, and eventually to the 
+///          ST cloud servers.
+///    
+///          You must connect the ESP-01 to the Arduino MEGA 2560's "Serial1" 
+///          Hardware Serial port on pins 18 & 19.  Google it!
+///
+///          The ESP-01 must be running a version of firmware compatible with
+///          the WiFiEsp library.  Try the examples in the WiFiEsp library
+///          to make sure everything is wried correctly before trying this sketch!
