Product Description
Sound Activated Switch Kit – K36
Every wonder how “The Clapper” works? This circuit will turn on and off based on a loud sound such as clapping your hands. You can adjust the sensitivity (how loud of a sound will activate the circuit) from a pin drop to a Mack Truck Horn. Very practical for a variety of projects. Add a relay to turn on a light when your dog barks, or set off a siren when an intruder makes a loud noise. Elenco K36
