How to Make Arduino Based Radar Project Using Ultrasonic Sensor 2018

Hey, friends in this tutorial we are going to learn and make an Arduino Based Radar Project, Basically, The Radar Project is very useful for finding an object and they are widely used in navigation based systems and also they are used in the security-based system.

Today we will cover that how we can make Radar System using Arduino. Its very simple, only you need few components and some coding. Don’t worry I have uploaded the circuit diagram and coding for this project below. Arduino based Radar Project is very simple and interesting project. But before starting project let me tell you about RADAR and RADAR Based Project.

What is Radar?

RADAR stands for RADIO DETECTION AND RANGING. Radar is equipment which is used to detect objects using Radio Waves. It discovers and studies remote targets by sending a radio pulse within the direction of the target and receives the reflection of the wave.

So what this Project Arduino Based Radar Project will perform?

This is very Simple Arduino Based Radar Project” whenever any object will come near to its range it will sense it and then it will produce output on Radar. It will indicate the presence of the object on Radar. Also, you can modify the project according to your need, you can make any type of security based system using this concept. Do whatever you want it just depends on your coding skills.
So Before Starting this Project Let me tell you what we will need to make this Project.

Components Required for Arduino Based Radar Project Using Ultrasonic Sensor:

Software Required:

Note:(Download these IDE’s click on the hypertext and download these IDE’s)

Why are we using these Components?

Here we are using Arduino to control codes and perform the required objective. for example, here we are using Arduino to Perform Radar Project operation to do that we need other components like Ultrasonic Sensor which is usually used for measuring distance here it will measure distance and it will give that measured data to the Arduino, and also we are using Servo Motor basically, Servo Motor works on the angle principle it means its rotations is based on angles so it will give us rotation on different angles.

Here we are putting the Ultrasonic sensor on the servo motor and it will move on the particular angles and whenever ultrasonic sensor will receive the signal it will send that signal to the Arduino and the Arduino will send that data to the Processing IDE which will show the visual presence of that object on RADAR. I hope it’s quite clear now.

Make sure you have connected all the connections like this. After connecting all the connections like this click below and download the required files for this ARDUINO BASED RADAR Project.

Files are:

Now Open your Arduino IDE if you don’t have then click above to download them. After download Arduino IDE open it and copy the code from Arduino Based Radar Project Code and paste it on the IDE. Then simply click on UPLOAD. Now open Processing IDE and paste the Processing code into it and then click on start.

Now place any object in front of Radar and see Processing is showing the detection of that object visually on the radar. if you have any confusion just follow this video then. I hope you have understood all the required things. if yes then I am satisfied otherwise just comment below and tell me what query you have.

Arduino Code for Arduino Based Radar Project Using Ultrasonic Sensor:

// Includes the Servo library
#include <Servo.h>.
// Defines Tirg and Echo pins of the Ultrasonic Sensor
const int trigPin = 10;
const int echoPin = 11;
// Variables for the duration and the distance
long duration;
int distance;
Servo myServo; // Creates a servo object for controlling the servo motor
void setup() {
pinMode(trigPin, OUTPUT); // Sets the trigPin as an Output
pinMode(echoPin, INPUT); // Sets the echoPin as an Input
Serial.begin(9600);
myServo.attach(12); // Defines on which pin is the servo motor attached
}
void loop() {
// rotates the servo motor from 15 to 165 degrees
for(int i=15;i<=165;i++){
myServo.write(i);
delay(30);
distance = calculateDistance();// Calls a function for calculating the distance measured by the Ultrasonic sensor for each degree

Serial.print(i); // Sends the current degree into the Serial Port
Serial.print(","); // Sends addition character right next to the previous value needed later in the Processing IDE for indexing
Serial.print(distance); // Sends the distance value into the Serial Port
Serial.print("."); // Sends addition character right next to the previous value needed later in the Processing IDE for indexing
}
// Repeats the previous lines from 165 to 15 degrees
for(int i=165;i>15;i--){
myServo.write(i);
delay(30);
distance = calculateDistance();
Serial.print(i);
Serial.print(",");
Serial.print(distance);
Serial.print(".");
}
}
// Function for calculating the distance measured by the Ultrasonic sensor
int calculateDistance(){

digitalWrite(trigPin, LOW);
delayMicroseconds(2);
// Sets the trigPin on HIGH state for 10 micro seconds
digitalWrite(trigPin, HIGH);
delayMicroseconds(10);
digitalWrite(trigPin, LOW);
duration = pulseIn(echoPin, HIGH); // Reads the echoPin, returns the sound wave travel time in microseconds
distance= duration*0.034/2;
return distance;
}
