Arduino Smart Dustbin Science Project with HC-SR04

Arduino Automatic Smart Dustbin Science Project Kit The Smart Dustbin Science Project Kit is an engaging Arduino-based project designed for school, college, and science fair activities. Using an HC-SR04 Ultrasonic Sensor, the dustbin detects objects within 20cm and automatically opens the lid using an SG90 Servo Motor. After placing waste, the lid closes automatically, creating a hands-free smart dustbin experience while helping students learn automation, sensors, and robotics concepts.
