Build a Touchless Smart Dustbin with Arduino Uno & Ultrasonic Sensor – Beginner Kit

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Imagine a dustbin that opens its lid automatically when you bring your hand near, then closes quietly after 3 seconds — no touching, no germs, no messy foot pedals. With this kit, you’ll turn a simple bin into a smart, hands-free gadget that responds to motion. It’s a first step into home automation and a perfect way to see how ultrasonic sensors and servos work together to solve everyday problems.

What You'll Build

You’ll assemble a working prototype of an automatic dustbin using an Arduino Uno, HC-SR04 ultrasonic sensor, and SG90 servo. When your hand approaches within a set distance, the sensor triggers the servo to lift the lid. The lid stays open as long as your hand is near, then closes automatically after 3 seconds of no movement. The entire circuit is built on a solderless breadboard, so you can test, tweak, and proudly show how contactless waste disposal works.

What You'll Learn

• Interfacing an HC-SR04 ultrasonic distance sensor with Arduino Uno to measure proximity
• Controlling an SG90 servo motor with precise timing for lid opening and closing
• Assembling electronic components safely on a 400-point breadboard without soldering
• Uploading and modifying Arduino code to create a real-world automation project
