Build a Sound-Activated RGB LED with Arduino

Connect a sound sensor and an RGB LED to your Arduino. Every time the sensor detects a loud enough sound — like a clap — the LED cycles to a new color. You will learn how digital sensors produce a falling edge, why that edge needs to be caught only once, and how to prevent a single clap from registering as five.
