This kit lets you build exactly that using an Arduino Uno, an HC-SR04 ultrasonic sensor, and a micro servo, transforming a regular household bin into a hands-free hygiene gadget. It is a perfect first step into home automation and sensor-driven electronics for young makers and students.\u003c\/p\u003e\n\n\u003ch2\u003eWhat You'll Build\u003c\/h2\u003e\n\u003cp\u003eYou will assemble a fully functional smart dustbin system that detects hand proximity within a few centimetres and triggers a servo motor to lift the lid. The lid stays open as long as your hand is near and closes automatically when you move away. This tangible, real-world device not only looks impressive but also solves a genuine hygiene problem at home or in school labs.\u003c\/p\u003e\n\n\u003ch2\u003eWhat You'll Learn\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eHow to interface an HC-SR04 ultrasonic sensor with Arduino to measure distance\u003c\/li\u003e\n  \u003cli\u003eControlling a servo motor based on sensor data to create mechanical movement\u003c\/li\u003e\n  \u003cli\u003eBasic circuit building on a breadboard with resistors and jumper wires\u003c\/li\u003e\n  \u003cli\u003eWriting and uploading Arduino code for real-time sensor-actuator loops\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\u003eHC-SR04\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eSG90 Servo\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e220?
