How to Set Up an Ultrasonic Range Finder on an Arduino

In this video, I show you how to measure distance with three different ultrasonic range finder circuits using the HC-SR04 Ultrasonic Range Finder. The first circuit is a basic range finder circuit using only an Arduino and the ultrasonic range finder. Then I show you a more accurate range finder circuit that factors temperature into the speed of sound formula. Finally, I show you the most accurate range finder circuit that takes into account both humidity and temperature in the equation for the speed of sound.
