Arduino - Ultrasonic sensor HC-SR04 Interfacing Example and Explaination of the theory behind.
HC-sr04 ultrasonic sensor interfacing with Arduino uno and other related Arduino like boards. The code used in this video use pulseIn function of Arduino uno core to calculate the length of incoming pulse.
Arduino is very famous board for rapid prototyping and learning as well as checking the working of the sensors. Because you will almost find any kind of library for your board. So it is always better to test your sensor with Arduino first. Just like we used Arduino Uno for demonstrating the working principle of the HC-SR04 Ultrasonic sensor with Arduino.
