tone command no longer plays frequencies accurately #361

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago

What steps will reproduce the problem?
1.upload ToneMelody example
2.Should play "Shave and a haircut"
3.Pitch is too low

Sounds like PWm frequency changed and screwed Tone up.  Pitches from 
"pitches.h" are no longert accurate. Tested this on an Uno and a Duemilanove in 
0020 and 0019

Adding a noTone() before changing frequencies seems to help.
