Control the buzzer's loudness with a resistor
Resistance doesn't just dim lights — it turns volume down too. Same principle, different output.

Steps
1Build a battery → buzzer loop and note the volume.
2Snap the resistor into the line — either way round.
3The buzz drops. Resistance limits current to any output.
4Try two resistors in a row. Quieter still?
