Smart Trash Can Auto-Open Kit v4: Touchless Bin Project with Raspberry Pi Pico

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 reaching toward a bin and having it open automatically - no touch, no germs, just a smooth, hands-free experience. This kit lets you build exactly that: a smart trash can that opens its lid when your hand approaches. Using a Raspberry Pi Pico and an HC-SR04 ultrasonic sensor, the system measures distance in real time and displays it on a clear OLED screen. A buzzer sounds if you get too close, making the project both practical and fun to assemble.

What You'll Build

You'll create a fully functional touchless trash can prototype on a breadboard. The HC-SR04 sensor detects when an object (like a hand) enters its field, updating the 0.96-inch OLED with precise distance measurements in centimeters and inches. If the object comes within 10 centimeters, the active buzzer triggers an alert - mimicking the lid-opening threshold of a real automatic bin. This hands-on project transforms a simple idea into a working gadget that you can demonstrate or integrate into a actual dustbin.

What You'll Learn

• Interfacing an HC-SR04 ultrasonic sensor and reading distance pulses with MicroPython
• Driving a 0.96-inch OLED display to show real-time data in cm and inches
• Programming an active buzzer to trigger an alarm when a distance threshold is crossed
• Assembling a multi-component breadboard circuit with a microcontroller and sensors, no soldering required
