This kit lets you build a smart light controller that turns a lamp on or off with a deliberate double clap - no buttons, no contact. It uses a KY-038 microphone to capture sound, an Arduino Uno to recognize the rhythm, and a relay module to switch a high-voltage load. Within a couple of hours, you'll hold a tangible safety device that demonstrates how everyday electronics can make workplaces smarter and safer.\u003c\/p\u003e\n\n\u003ch2\u003eWhat You'll Build\u003c\/h2\u003e\n\u003cp\u003eYou'll assemble a complete noise-responsive lamp controller on a breadboard. The microphone picks up audio, the Arduino code filters out background noise and confirms a true double-clap pattern, and the relay toggles a connected lamp. The kit includes two indicator LEDs: one signals power, the other lights up with each detected clap. By the end, you'll have a desktop prototype ready to be adapted to a real 230V bulb, demonstrating an industrial principle that's simple enough for a school project and robust enough to spark bigger ideas.\u003c\/p\u003e\n\n\u003ch2\u003eWhat You'll Learn\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eInterface a sound sensor module with an Arduino and read analog sound levels\u003c\/li\u003e\n  \u003cli\u003eWrite code that detects a specific double-clap sequence and ignores random noise\u003c\/li\u003e\n  \u003cli\u003eUse a 5V relay module to safely control high-voltage home or lab appliances\u003c\/li\u003e\n  \u003cli\u003eWire a multi-component circuit on a breadboard without any soldering\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eKit Contents\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eComponent\u003c\/th\u003e\n\u003cth\u003eQuantity\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003eArduino Uno R3\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eKY-038 Sound Sensor\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e5V Relay Module\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e5mm LED\u003c\/td\u003e\n\u003ctd\u003e2\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e1N4007 Diode\u003c\/td\u003e\n\u003ctd\u003e3\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e10k?
