LESSON 17: Measure Speed of Sound with Arduino and Ultrasonic Sensor
This tutorial presents simple step-by-step instructions on how to accurately measure the speed of sound using an arduino microcontroller and an ultrasonic sensor. It operates based on echolocation, and is similar to the mechanism used by bats to navigate in a dark cave. It is also similar to how Sonar works on submarines.
