Arduino ultrasonic sensor code for distance measurement.
Distance measurement using ultrasonic sensor and arduino uno code.
Ultrasonic sensors not only offer distance measuring utility without any physical contact but enable us to measure with no noise and light unlike laser based distance measuring instruments.

In code we read time by using pulsein pin.
In this tutorial we ll understand the working of ultrasonic sensor understand the arduino program for distance measurement using ultrasonic sensor hc sr04.
It sends an ultrasonic wave of a certain frequency that comes back after hitting the object and calculates the time traveled by it.
And then perform calculations and displayed result on 16x2 lcd by using appropriate functions.
