#include <Servo.h>

#include <NewPing.h>

#define TRIGGER_PIN  12  // Arduino pin tied to trigger pin on the ultrasonic sensor.

#define ECHO_PIN     11  // Arduino pin tied to echo pin on the ultrasonic sensor.

#define MAX_DISTANCE 200 // Maximum distance we want to ping for (in centimeters). Maximum sensor distance is rated at 400-500cm.

NewPing sonar(TRIGGER_PIN, ECHO_PIN, MAX_DISTANCE); // NewPing setup of pins and maximum distance.

Servo myservo;//create servo object to control a servo

int distance;

void setup() {

  myservo.attach(9);//attachs the servo on pin 9 to servo object

  myservo.write(0);//back to 0 degrees 

  delay(1000);//wait for a second

  Serial.begin(9600); // Open serial monitor at 115200 baud to see ping results.

}

void loop() {

  delay(500);  // 

  unsigned int uS = sonar.ping(); // Send ping, get ping time in microseconds (uS).

  Serial.print("Ping: ");

  Serial.print(uS / US_ROUNDTRIP_CM); // Convert ping time to distance and print result (0 = outside set distance range, no ping echo)

  Serial.println("cm");

 

  distance = uS / US_ROUNDTRIP_CM;

  delay(500);

  // Servo motor moves when the distance is less than 5cm

  if (distance < 5 && distance != 0) {

    Serial.println("distance : ");

    Serial.println(distance); 

    myservo.write(90);//goes to 45 degrees 

    delay(500);

    myservo.write(-90);//goes to 45 degrees

    delay(500);

  }

}

==> Servo motor will move 90 degree and -90 degree when ultrasonic sensor detects object (person) in 5 cm.

Ultrasonic sonic sensor is going to be a pet's head so it looks like the pet is shaking his head because he doesn't like the person.

==> This is practice project of the project "I like you"

with the project, As you move, the pet will keep looking at you.

So the project name is "I like you" 

==> to do that I am planning to use 2 (or 3) ultrasonic sensor.

Anyway for the practice project "I don't like you", Arduino components should be configured as follows.

It will print the distance in 'cm' if it is run.
