Acts like a keyboard that prints sensor
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

At startup, it does nothing. It waits for you to open a
spreadsheet (e.g. Google Drive spreadsheet) so it can write
data. 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.
The amount of time between each row is determined 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.
