Radar System using Arduino

                       Radar System using Arduino

                                        The Radar is Basic Tool used For the Navigation and Tracking object Nearby.The radar is widely used in Military,AirControl systems.Thus the radar is widely used for various applications.Thus we are going to make it in the Arduino using Ultrasonic sensor.

Components Required:

                              1)Arduino

                              2)Ultrasonic Sensor

                              3)Servo Motor

                              4)Male To Female Port wires

 Procedure:

                               The ultrasonic sensor is used between 40 cm to detect object with help of Arduino and next connect the ultrasonic sensor to the Arduino which is defined in the Code and samewise Connect the servo to the Arduino.Now Upload the code which is Given below and next upload Code of Processing App Code to it.Nect press the play Button.Then the mini rador works.

                             myPort = new Serial(this,"COM5", 9600);

                      Set the COM to which your Arduino connected

Arduino Code:

 // NBSL COMMERCIAL
#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;
}
