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.\u003c\/p\u003e\n\n\u003ch2\u003eWhat You'll Build\u003c\/h2\u003e\n\u003cp\u003eYou'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.\u003c\/p\u003e\n\n\u003ch2\u003eWhat You'll Learn\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eInterfacing an HC-SR04 ultrasonic sensor and reading distance pulses with MicroPython\u003c\/li\u003e\n  \u003cli\u003eDriving a 0.96-inch OLED display to show real-time data in cm and inches\u003c\/li\u003e\n  \u003cli\u003eProgramming an active buzzer to trigger an alarm when a distance threshold is crossed\u003c\/li\u003e\n  \u003cli\u003eAssembling a multi-component breadboard circuit with a microcontroller and sensors, no soldering required\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eKit Contents\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eComponent\u003c\/th\u003e\n\u003cth\u003eQuantity\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003eRaspberry Pi Pico\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eHC-SR04 Ultrasonic Sensor\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e0.96in OLED Display\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\u003ctd\u003eActive Buzzer\n\n\u003cdiv class=\"kit-description\"\u003e\n  \u003cp\u003eTouchless Bin - HC-SR04 ultrasonic returns distance in MicroPython.
