Story

Hello friends welcome back to "Techno-E-Solution", In this tutorial we are going to make cool project "Arduino Radar System Using Ultrasonic Sensor & Arduino Uno" using Processing Application. Radar is a object detecting system, It uses microwaves to determine the range, direction, speed, altitude of object. In Arduino Radar system we use Arduino Uno & Ultrasonic Sensor to detect objects and small servo motor to rotate ultrasonic sensor. You know the radar is long range object detecting system, Usually Radar system is used in Marine, Aircrafts, Missiles, etc.

If you like my project follow me for my latest project :-

So without wasting time, Let's get started.............

Here is complete video tutorial for Arduino Radar system.
