Re: playTone duration in Arduino package

Here is an annotated interactive session that I hope answers John's
questions (Octave version is 5.2.0, on Windows 10, arduino version looks
like 0.6.0):

>> pkg load arduino
>> a=arduino()
a =
  arduino object with fields of:
    port = \\.\COM4
    board = uno
    libraries = {
      i2c
      spi
      servo
      shiftregister
    }
    availablepins = {
      d0 - d13
      a0 - a5
    }
>> playTone(a,'D10',440,1) %piezo speaker is attached to D10 and makes a
tone that never stops
>> playTone(a,'D10',300,1) %frequency changes but never stops
>> playTone(a,'D10',0,1) %sound stops
>> playTone(a,'D10',180,3) %makes a tone that never stops
>> playTone(a,'D10',440,0) %frequency changes but never stops
>> version   %I think this gives the version of octave
ans = 5.2.0

>> pkg list  %It looks like arduino package version is 0.6.0
Package Name         | Version | Installation directory
---------------------+---------+-----------------------
            arduino *|   0.6.0 |
...\OCTAVE~1.0\mingw64\share\octave\packages\arduino-0.6.0
              audio  |   2.0.0 |
C:\Octave\OCTAVE~1.0\mingw64\share\octave\packages\audio-2.0.0
     communications  |   1.2.2 |
...\mingw64\share\octave\packages\communications-1.2.2


It is my understanding that the last parameter is supposed to be duration
in seconds. So I'd expect the tones to stop after that time has elapsed.

Thanks.
