Smart Dustbin
This project uses an ultrasonic sensor to detect when someone is near the dustbin and automatically opens the lid using a servo motor. The lid closes automatically after a few seconds.
Project Instructions
Fix an ultrasonic sensor on the dustbin.
Connect servo motor to control lid.
Upload Arduino code to read sensor distance.
If distance < 20cm, open lid.
Close lid after 5 seconds if no one is near.
Materials Required
Arduino Uno / Nano
Servo motor (SG90 or similar)
Ultrasonic sensor (HC-SR04)
Jumper wires
Breadboard (optional)
USB cable for Arduino
Code & Programming
Arduino continuously reads sensor distance. If an object is detected within a threshold, it rotates the servo to lift the lid.
