Inside the 3D printed enclosure is an Arduino Pro Mini, a HC-SR04 ultrasonic sensor, ... As simple as this project may sound like for anyone who has a bunch of these little Arduino-compatible ...

🛠️ Components Used 🔹 Arduino Uno – Microcontroller for processing sensor data. 🔹 HC-SR04 Ultrasonic Sensor – Measures distance using sound waves. 🔹 LEDs (5x) – Visual indicators for different ...

So I removed this servo and IR sensors and use 3 ultrasonic sensors. With ultrasonic sensors, you can measure distance and use that information to navigate and follow a human target. Here’s a general ...

Ultrasonic sensors have become commonplace thanks in considerable measure to adoption in early-stage autonomous driving vehicles. Ultrasonic technology uses mostly inaudible sound waves (starting at ...

Ultrasonic double-sheet detectors distinguish between single and double sheets of paper, plastic, or metal foils to prevent waste or machine damage. The sensor operates by beaming ultrasonic sound ...

Sensor Sense: Eliminating ultrasonic cross talk May 10, 2007 Proximity sensors that use ultrasonic sound waves calculate distance to an object using the time it takes to receive the echo from an ...

Instead, it relies on an ultrasonic distance sensor to detect a hand (or foot) waved in front of the door. An Arduino Leonardo runs the show, sounding a buzzer when the ultrasonic sensor is triggered.
