This project uses a sound sensor to detect a "clap" (loud noise) and toggle an LED or appliance. Hardware Needed: Arduino Uno or similar board. Sound Sensor Module (e.g., KY-038 or similar). LED (with a 220-ohm resistor). Breadboard and jumper wires. The Code:
: A knob that changes the color of a multi-color LED.
