I have a 9v square battery connected to a pezio buzzer and i want to use a potentiometer to vary the tone of the buzzer. So when the potentiometer is at its highest resistence the buzzer does not sound and at its lowest its at full. What im unsure of is what resistance potentiometer i need to get? Any help appreciated.
As an aside, any thoughts on how to vary the volume of the buzzer without changing the tone?
