-  Esplora Table
-
-  Acts like a keyboard that prints some of its sensors'
-  data in a table-like text, row by row.
-  It is a sort of "data-logger".
-  
-  At startup, it does nothing. It just waits for you to open a
-  spreadsheet (e.g. Google Drive spreadsheet) so it can put its
-  data. Then, by pressing Switch 1, it starts printing the table
-  headers and the first row of data. It waits a bit, then it
-  will print another row, and so on.
-  
-  The amount of time between each row is given by the slider.
-  If put to full left, the sketch will wait 10 seconds; at
-  full right position, it will wait 5 minutes. An intermediate
-  position will make the sketch wait for some time in-between.
-  
-  Clicking the Switch 1 at any time will stop the logging.
-
-  The color LED shows what the sketch is doing:
-  blue  = idle, waiting for you to press Switch 1 to start logging
-  green = active; will print soon
-  red   = printing data to the PC
