My Arduino project is a level indicator that uses a Piezo transducer.
I've used the "tone" function to manipulate the sound to raise the pitch when the desired level is reached.
With the 'tone' function I can very precisely control the pitch and speed of the speaker.
However, the project runs from a Lipo battery, and even with 5 volts, the transducers i've tried don't get very loud.
I wish to limit my projects size and complexity as much as possible.
This is why I'd rather not use a boost...
