Smart Dustbin using Arduino

Smart Dustbin Project Report

Introduction:

This project aims to develop a smart dustbin that automatically opens and closes its lid using an ultrasonic sensor and Arduino. This eliminates the need for manual contact, promoting hygiene and convenience.

Components:

• Arduino Nano
• Ultrasonic Sensor (HC-SR04)
• Servo Motor
• Dustbin
• Jumper wires
• Breadboard (optional)
• Power supply

Functioning:

1. Object Detection: The ultrasonic sensor continuously emits ultrasonic waves and measures the time it takes for the reflected waves to return. This time is then used to calculate the distance between the sensor and the nearest object.
2. Lid Control: When an object (hand) comes within a pre-defined range (e.g., 10 cm) of the sensor, the Arduino sends a signal to the servo motor, triggering it to open the dustbin lid.
3. Automatic Closure: Once the object moves away from the sensor, exceeding the threshold distance, the servo motor receives another signal, causing the lid to close automatically.
