In this video, I built a Smart Automatic Trash Can using Arduino, but with a unique twist —
instead of a normal lid, I have used a 3D Printed Iris Mechanism that opens and closes automatically!

The ultrasonic sensor detects your hand, and the servo motor rotates the iris blades smoothly to open the trash can. After a few seconds, it closes automatically.
This gives the project a premium & futuristic look, just like sci-fi gadgets.

🎯 Components Used:

Arduino Uno

Ultrasonic Sensor (HC-SR04)

SG90 / MG90 Servo Motor

3D Printed Iris Mechanism

Wires + Basic tools

⚙ How It Works

1. Ultrasonic sensor detects motion (hand).
2. Arduino triggers the servo to rotate the iris opening mechanism.
3. Iris opens smoothly like a camera aperture.
4. After 2–3 seconds it closes automatically.
