Highlights:

The mechanical buzzer uses a magnet to move a reed up and down quickly to emit a lower-pitched buzz! It’s quieter than the piezoelectric buzzer but uses more power, so place it closer to the battery holder in your dough circuit. To use it, match the wire colors to the wires from the battery holder.

If the volume is too loud, simply use a piece of tape over the top hole on the buzzer, and the volume will be substantially lower.
