Smart Dustbin Lid Kit with Arduino Uno & HC-SR04 – Build a Touchless Bin for Hands-Free Waste Disposal

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 walking to your dustbin with messy hands and the lid opens by itself – this kit brings that smart home experience to life. Using the HC-SR04 ultrasonic sensor and an SG90 servo, you’ll build a lid that detects your hand and swings open within seconds, then closes automatically. Perfect for school exhibits, home hacks, or a first dive into Arduino-based home automation.

What You'll Build

You’ll assemble a fully functional automatic dustbin lid that lifts when an object (like a waving hand) comes within 15 cm. The circuit sits on a breadboard, the servo shaft attaches to a small lid flap, and the ultrasonic sensor continuously scans for a trigger. Once you load the code, the lid responds smoothly and predictably. You can mount the prototype on any existing bin or a cardboard model.

What You'll Learn

• Interface an HC-SR04 ultrasonic sensor with Arduino Uno to read distances
• Control an SG90 servo motor based on a threshold distance
• Understand sensor calibration and trigger logic for real-world use
• Debug sensor-actuator systems on a solderless breadboard
