This kit includes all the  components needed for building a sensitive sound trigger. The SK2 uses a piezoelectric element that is sensitive to sharp sounds like claps, snaps, and bursts. It can trigger on a finger snap from a distance of about 10 feet. A photo of the trigger assembled on a breadboard is shown to the right. The circuit is powered with a 9-V battery or AC/DC adapter (not included).

 

Cords to connect the breadboard circuit to a flash unit or camera are not included.
