=========================
Arduino Distance Finder:-
==========================
This is a breadboard based project by which we can find the distance in cm using Ultrasonic Sensor.
We can get our output on 16x2 LCD screen or Serial Monitor in Arduino IDE at the same time.

===============
Requirements:-
===============
1- Arduino Mega or UNO (code can be modified)
2- Potentiometer (eg 5K)  (optional)
3- LCD 16x2 (optional)
4- Ultrasonic sensor
