CODE

Before coding, you have to install new ping library

https://drive.google.com/open?id=11gy_6v61-Eq0sAz8RJF_sn5Tl0g7z8Cj

Sketch > Include library > Manage Library > Search NEWPING library > download it

Or you download NewPing Library from other site.

RUN SKETCH AND VERIFY OUTPUT

After compiling, uploading and running it

As far as the object goes far from the ultra-sonic sensor, Distance will be vary and measured distance will be show in LCD

in the Serial Monitor (Tools -> Serial Monitor or Ctrl + Shift + M) the sensor was sending correct data

Note: Must Set the baud Rate to 115200

Ping: 36 cm or the value shown in the serial monitor depends on the object distance from the ultra-sonic sensor.
