Introduction

In this project, I will show you how to design a simple Radar Application using Arduino and Processing.
This Arduino Radar Project is implemented with the help of Processing Application.
Radar is a long-range object detection system that uses radio waves to establish certain parameters of an
object like its range, speed and position. Radar technology is used in aircrafts, missiles, marine, weather
predictions and automobiles.

Even though the title says Arduino Radar Project, technically the project is based on Sonar technology as
I will be using an Ultrasonic Sensor to determine the presence of any object in a particular range.

Project Overview

The Arduino Radar Project is more of a visual project than it is a circuit implementation. Of course, I will
be using different hardware like Arduino UNO, HC-SR04 Ultrasonic Sensor and a Servo Motor but the
main aspect is the visual representation in the Processing Application.

If you remember, I have already used the Processing Application in one of the earlier Arduino Projects
involving MPU-6050 Sensor. I suggest you to take a look at that project before proceeding (you don’t
have to actually implement the project but understand the way it is implemented).

Reference: GETTING STARTED WITH ARDUINO AND MPU6050

In the MPU-6050 Project, I have used Arduino to read the data from the MPU-6050 Sensor and send it to
Processing Application through the COM Port (Serial Communication).

Based on the information received, a sketch in Processing will change the orientation of the model
aircraft.

Taking the same concept here, I will collect the information from the Ultrasonic Sensor with the help of
Arduino and pass it to Processing where a simple Graphics application is implemented to mimic a Radar
Screen.
Output Video

Before proceeding with the circuit diagram and rest of the things, take a look at the output in the
following video.

Circuit Diagram of Arduino Radar Project

The circuit diagram of this Radar Project is very simple as it involves very little hardware.

Circuit Design

If you look at the circuit diagram, the design of the circuit for this project is very simple. The control pin
of the servo is connected to Pin 11 of the Arduino while the TRIG and ECHO Pins of the Ultrasonic Sensor
are connected to Pins 9 & 10 of Arduino respectively.

Arduino Radar Project Image 2

A separate 5V power supply (with common GND) is given to the Servo Motor and the Ultrasonic Sensor.

Getting the Hardware Ready

After making the connections, there is one important step in the construction you need to perform (not
mandatory). Since the Ultrasonic Sensor must sweep an arc of 1800 (with the help of the Servo), I have
used a mounting bracket as shown in the image below to fix the Ultrasonic Sensor.

Arduino Radar Project Mounting Bracket

After fixing the sensor, the mounting bracket is screwed to the servo motor as shown below. As the
bracket and the Ultrasonic Sensor adds weight to the servo, make sure to use a double-sided-tape to fix
the Servo firmly to the surface.

This step is optional and you can make a simple structure with cardboard to hold the Ultrasonic Sensor
firmly to the Servo.

A Reminder on Processing

If you are new to processing, it is a visual arts based software for learning to code. To download the
application, visit the following link and choose your platform. Download Processing.

After downloading the Zip file (assuming the platform is 64-bit Windows), extract the contents of the zip
file and you can find the processing application (.exe file).
The next step is to download a special library called “Toxi” from this link. After downloading the
“toxiclibs-complete-0020” zip file, extract the contents to the folder of same name and move that folder
to the Processing libraries directory (something like C:\Users\Ravi\Documents\Processing\libraries).

Code

There are two codes for this project: one for the Arduino UNO and the other for the Processing.

Arduino Code

The code for Arduino UNO is given below.

#include <Servo.h>

const int trigPin = 9;

const int echoPin = 10;

long duration;

int distinCM;

Servo radarServo;

void setup()

pinMode(trigPin, OUTPUT);

pinMode(echoPin, INPUT);

Serial.begin(9600);
 radarServo.attach(11);

void loop()

for(int i=0;i<=180;i++)

radarServo.write(i);

delay(50);

digitalWrite(trigPin, LOW);

delayMicroseconds(2);

digitalWrite(trigPin, HIGH);

delayMicroseconds(10);

digitalWrite(trigPin, LOW);

duration = pulseIn(echoPin, HIGH);

distinCM = duration*0.034/2;

Serial.print(i);

Serial.print("*");

Serial.print(distinCM);

Serial.print("#");

for(int i=180;i>=0;i--)

{
 radarServo.write(i);

delay(50);

digitalWrite(trigPin, LOW);

delayMicroseconds(2);

digitalWrite(trigPin, HIGH);

delayMicroseconds(10);

digitalWrite(trigPin, LOW);

duration = pulseIn(echoPin, HIGH);

distinCM = duration*0.034/2;

Serial.print(i);

Serial.print("*");

Serial.print(distinCM);

Serial.print("#");

Working

Initially, upload the code to Arduino after making the connections. You can observe the servo sweeping
from 00 to 1800 and again back to 00. Since the Ultrasonic Sensor is mounted over the Servo, it will also
participate in the sweeping action.

Now, open the processing application and paste the above given sketch. In the Processing Sketch, make
necessary changes in the COM Port selection and replace it with the COM Port number to which your
Arduino is connected to.

If you note the Processing Sketch, I have used the output display size as 1280×720 (assuming almost all
computers now-a-days have a minimum resolution of 1366×768) and made calculation with respect to
this resolution.

In the future, I will upload a new Processing sketch where you can enter the desired resolution (like
1920×1080) and all the calculations will be automatically adjusted to this resolution.

Now, run the sketch in the Processing and if everything goes well, a new Processing window opens up
like the one shown below.

Arduino Radar Project Processing Output

A Graphical representation of the data from the Ultrasonic Sensor is represented in a Radar type display.
If the Ultrasonic Sensor detects any object within its range, the same will be displayed graphically on the
screen.
