Distance measure with servo motor and ultrasonic sensor

 

    Ultrasonic sensors can gauge the distance to a wide scope of items paying little mind to shape, shading or surface. They are additionally ready to gauge a drawing nearer or subsiding object. By utilizing "non-contact" ultrasonic sensors, distances can be estimated without harm to the article.

COMPONENT REQUIREMENT:

1. ARDUINO UNO 2. ULTRASONIC SENSOR 3. BREADBOARD 4. SERVO MOTOR 5. CARD BOARD 6. JUMPER WIRE

PROCEDURE:

    STEP - 1

         Take the card board and mark the measurement in centimeter (cm). Cut the rectangle shape in card board to glue the servo motor with a needle.

    STEP - 2

         Fix the ultrasonic sensor into the breadboard and connect the jumper wire. Spot the red jumper wire as positive and black jumper wire as negative.

    STEP - 3

         Connect the wire as given below,

            * Ultrasonic sensor VCC to Positive of the breadboard

            * Ultrasonic sensor Trig to Arduino Pin-6

            * Ultrasonic sensor Echo to Pin-7

            * Ultrasonic sensor GND to Negative of the breadboard

            * Breadboard positive ( Red jumper wire ) to Arduino 5V

            * Breadboard negative ( Black jumper wire ) to Arduino GND

        

STEP - 4

     Connect the measurement board jumper wire into the Arduino board as given below,

                * Servo motor yellow jumper wire to Arduino Pin-10

                * Servo motor Red jumper wire to Positive

                * Servo motor Brown jumper wire to Negative

    STEP - 5

          Upload the source code to the Arduino board

#include <Servo.h> #include <NewPing.h> const int ServoPin = 10; const int TriggerPin = 6; const int EchoPin = 7; // 100 = maxDistance NewPing sonar (TriggerPin, EchoPin, 100); Servo servo; void setup() { Serial.begin(9600); servo.attach(ServoPin); } void loop() { int cm = sonar.ping_cm(); Serial.println(cm); int angle = map(cm, 2, 15, 15, 100); servo.write(angle); delay(50); }

    STEP - 6

         At the point when ultrasonic sensor recognizes the object, the needle shows the distance in the estimation board. 

NOTE:

    Error:

        Incase the error happens like new ping, go and refer the solution given below.

    Solution:

       First you go to the tools and click the manage libraries. search the "new ping.h" and install.
