In this project we have two code first for Arduino sketch to move the servo and take the data from ultrasonic sensor, and second for processing sketch to make interface simulate the radar.

Radar was developed as a method of detecting enemy aircraft in World War 2. Along with the developments in technology, these days it is used in a wide range of sectors. Since the last few decades, there have been significant advancements in the use of radar technology.

In this project, we are going to design an Arduino radar project using Ultrasonic Sensor for detection. An Arduino microcontroller makes electronics more discipline.

This Arduino radar project aims to achieve a radar system prototype based on an Arduino board that detects stationary and moving objects. The radar system has different performance specifications, and it is also available in a variety of sizes.

We need two software to complete this Arduino radar project. One is Arduino IDE, and the other is Processing IDE.

Processing application is visual arts-based software for learning to code. After downloading, extract the Zip file, and you will get the processing application (.exe file).

In this project, we are using two codes: Arduino UNO and the other for Processing.

After uploading the code, the servo motors start running from 0 to 180 degrees and again back to 0 degrees. An ultrasonic sensor also rotates along with the servo as it is mounted on the motor.

Now, open the processing application and paste the above code. In this code, update the COM port number where your Arduino board is connected.

Now, run this processing code. If your code is right then, you will get a new window. This is the graphical representation of data from the Ultrasonic Sensor is represented in a radar type display.

If an ultrasonic sensor detects any object within its range, you can see the same on the graphical representation. The below gif shows the output of the Arduino radar project.
