Smart Trash Bin is an innovative waste management system designed to improve cleanliness and efficiency using technology. This system utilizes sensors, microcontrollers, and automation to detect the presence of objects and open the lid automatically without physical contact.

The main components of this project include an ultrasonic sensor to detect distance, a microcontroller (such as Micro:bit or Arduino) to process data, and a servo motor to control the lid movement. When a user approaches the trash bin, the sensor detects the object and sends a signal to the microcontroller, which then activates the motor to open the lid.

This system helps reduce physical contact with trash bins, making it more hygienic and suitable for public places such as schools, hospitals, and offices. Additionally, Smart Trash Bin can be further developed with features like waste level detection and IoT integration for real-time monitoring.

Overall, Smart Trash Bin is a simple yet effective solution to promote cleanliness, technology usage, and smart living in everyday life.
