Arduino Whistle Detector Switch using Sound Sensor

Turn sound into action with the ROBOTSKULL Whistle Detector Switch Kit, a fun and educational project that lets you control a 6V bulb using a whistle, clap, or any loud sound. Powered by an Arduino Uno SMD and triggered via a sound sensor, this kit activates a relay to switch a bulb ON/OFF based on audio input – making it a hit for automation projects, school science fairs, and home demos.
