I'm driving a piezo buzzer with the tone function and I can hardly hear the tones. I took the resister out of the circuit but it barely helped at all. Is there some fix or do I need a different buzzer?

Increase volume of tone()?

I just went ahead and got buzzers with a lower voltage rating. Now I have to find the right resistance to bring the level down to what I want.
