Build a Touchless Automatic Dustbin with the Blind Stick Obstacle Detector Mini Kit (Arduino Uno + Ultrasonic)

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 by itself when you approach it — no touching, no germs, perfect for kitchens, labs, and accessibility needs. This kit lets you build exactly that in just a few hours. Using an HC-SR04 ultrasonic sensor to detect a hand within 5-10 cm, the Arduino commands an SG90 servo to open the lid and automatically close it after 3 seconds.

What You'll Build

A compact automatic dustbin module that you can mount onto any bin. When you wave your hand or bring an object close, the lid swings open smoothly. It stays open for 3 seconds, then closes, keeping the environment hygienic. You can adjust detection distance and open duration in the code.

What You'll Learn

• Interfacing HC-SR04 ultrasonic sensor with Arduino Uno
• Controlling an SG90 servo motor using PWM signals
• Programming conditional logic and timing with Arduino IDE
• Building solderless circuits on a breadboard

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This kit is perfect for CBSE Class 11-12 students exploring sensor projects for practicals, B.Tech ECE/EEE students working on mini-projects, and participants of Smart India Hackathon building assistive technology prototypes. ATL Tinkering Lab mentors can use it to teach embedded systems and accessibility design. Young makers aged 10+ with adult supervision will also enjoy the hands-on experience.

Built and Backed by Compoden

Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
