To build a basic radar system using an Arduino and Processing (a language based on Java, often used for creating visual arts), you can combine a few components like an ultrasonic sensor to measure ...

The target arduino device is a Arduino nano v3. There are two folders containing source code: One called Radar_360_Final which contains code for Processing3 written in Java. This displays the Radar ...

Now, grab your Arduino Nano, plug in the USB cable, and upload the code that will make your DIY radar system actually work. The code is fairly long and we have included it at the end of this tutorial.

Next, we start the Processing application on the PC, and then we need to enter the correct serial port through which the Arduino communicates. This displays a Radar-like monitor on which the objects ...
