Hi, I am trying to power a Piezo Buzzer between 3.3VDC and 5VDC.
The voltage is being adjusted so the sound is low (at 3.3VDC) and loud(at 5VDC).
My attachment can be a little misleading. Alarm_low doesn't suggest the volume is low, just the number of beeps. Same holds true for Alarm_medium and Alarm_high.

I'm trying to figure a way to add a circuit like a Voltage Controlled Voltage source as observed in my attachment. Can anyone offer some advice?

Thanks,

Brian
