Arduino Distance Indicator +

OVERVIEW

In this project we will make a Distance Indicator using Arduino Uno, Ultrasonic sensor, and LEDs. we will detect ultrasonic waves to measure distance and turn on LEDs to show the distance between an object.

You can follow this video and instructions below to make this Amazing Arduino Distance Indicator Project.
