Smart Trash Can Auto-Open Kit with Arduino Uno
Smart Trash Can Auto-Open Pro Kit with Arduino Uno - Build a Touchless Dustbin for Home & School
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Build a touchless trash can that automatically opens its lid when your hand approaches - no buttons, no handles, just wave to open. This project is perfect for hygiene-conscious homes, school science exhibitions, and young makers eager to explore home automation with Arduino. In just a few hours, you'll have a fully functional prototype that demonstrates sensor integration and servo control.
What You'll Build
You'll assemble and program a smart dustbin using the HC-SR04 ultrasonic sensor to detect a hand within a preset distance (typically 15-25 cm). The SG90 servo motor smoothly lifts the lid, holds it open for a few seconds, and then closes it automatically. The entire circuit is built on a breadboard, making it easy to test and modify. Once complete, you can mount the mechanism on any small bin at home or in the classroom.
What You'll Learn
- How ultrasonic distance sensors work and how to wire them to Arduino.
- Servo motor control using pulse-width modulation (PWM) and the Arduino Servo library.
- Coding conditional logic to trigger actions based on sensor readings, including timing delays.
- Breadboarding techniques and circuit troubleshooting without soldering.

Who This Kit Is For
This kit is designed for absolute beginners, including CBSE Class 11-12 students working on physics or computer science practicals, ATL Tinkering Lab participants, and young innovators aged 5-15 exploring STEM. It's also a great choice for B.Tech first-year ECE/EEE students who want a hands-on introduction to embedded systems. Parents looking for a screen-free, educational weekend activity will appreciate the clear, guided build process.
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.
What if I get stuck during the build?
Our AI companion, accessible via the QR code included, provides step-by-step visual instructions. You can also reach us on WhatsApp for direct help from a real engineer.
Will this kit work with any dustbin?
The mechanism can be attached to most small household bins with a flip-up lid. A flat lid surface gives the best results; we show you a simple mounting method in the guide.
Do I need any prior coding experience?
No. The code is pre-written and explained line-by-line in the AI companion. You'll learn the basics as you upload it, and no modifications are required to get started.
Can I power the kit without a 9V battery?
Yes, the Arduino Uno can also be powered via a USB cable connected to a computer or power bank, though the 9V battery makes the project portable and self-contained.
Touchless Bin - HC-SR04 ultrasonic detects hand approach and servo opens the dustbin lid automatically.
