Arduino based Distance measurement using Ultrasonic sensor

The ultrasonic sensor is used to measure the distance. It acts as a Sonar. It sends an ultrasonic wave of a certain frequency that comes back after hitting the object and calculates the time traveled by it. So let’s learn about Distance Measurement Using Arduino & HC-SR04 Ultrasonic Sensor.
