+  Serial Event example
+
+  When new serial data arrives, this sketch adds it to a String.
+  When a newline is received, the loop prints the string and clears it.
+
+  A good test for this is to try it with a GPS receiver that sends out
+  NMEA 0183 sentences.
+
+  NOTE: The serialEvent() feature is not available on the Leonardo, Micro, or
+  other ATmega32U4 based boards.
+
