PING))) Wiring & Example Code

The Ping))) Ultrasonic Distance Sensor measures the roundtrip echo time of ultrasonic sound to determine how far away an object is. It can measure distances anywhere from 3 centimeters to 3 meters. In addition to being a great distance sensor for robots, it’s also useful for detecting people passing through doorways, viewing art exhibits, approaching holiday props, and more.
