Smart Automated Bin System
Automated smart trash bin with ultrasonic motion detection, servo-controlled lid opening, and LCD display showing distance measurements. Opens automatically when someone approaches and displays real-time proximity data.

Project Overview
Build an intelligent waste management system that opens automatically when someone approaches! This project combines multiple sensors and actuators to create a touchless, hygienic solution perfect for kitchens, offices, or public spaces.
The system uses an ultrasonic sensor to detect approaching people, a servo motor to smoothly open and close the lid, and an LCD display to show real-time distance measurements and system status. You'll learn about sensor fusion, mechanical control, and user interface design.
This project demonstrates practical IoT applications, introduces automation concepts, and can be enhanced with features like fill-level monitoring, data logging, and smartphone connectivity. It's perfect for understanding how smart home devices work.
