Story

i was given an arduino to mess around with, i remembered someone giving me some random electronics they found which contained the ultrasonic sensor(i only realized what it was after seeing other arduino sensors and realizing the similarities.) so i put it all together and made my project.

Code

A tape-less measuring tape - code

i did use other code like an example LCD test sketch and a serial output code for the sensor before putting them together myself.
