Whistle detector switch with Arduino

Turn ON and OFF a relay just by whistling. Open the door in the same way, turn on an LED strio or just count the times that you whistle. In this video I'll show you how to detect the whistle sound with a very basic circuit, and once detected control any action of an Arduino. Check all the links below. Thanks to all af you and to all my Patreons.
