Описание к видео HC-SR04 & Arduino Ultrasonic module - Getting Started.

Connecting and getting started with the HC-SR04 ultrasonic distance measuring module . This module is easy to use and doesn't require any library installs with results in just a few lines of code.This video describes how the module works, goes through some of the fundamentals of writing and reading to and from the digital pins on the Arduino and using pulse width modulation to simulate an analog voltage output.
PS: It was only intended to be a 5 minute tutorial...so apologies that it overruns somewhat!
