This video is unsing the HC-SR04 Ultrasonic module to measure the distance between the sensor and an object. We will learn how this senor is working and how to code it. Therefore we will use thie command pulseIn.

Commands explained:
pulseIn
delayMicroseconds

Hardware used:
HC-SR04 Ultrasonic sensor
