PING Ultrasonic Distance Sensor and Arduino

This video tutorial covers the use of an ultrasonic distance sensor with an Arduino. It explains how to connect the sensor to the Arduino, how the sensor operates using ultrasonic sound, and provides a detailed walkthrough of the example Arduino code. The tutorial also includes a programming challenge to add an LED that lights up when an object is closer than 10 cm to the sensor. Finally, it previews the next video, which will cover the HCSRO 4 ultrasonic distance sensor.
