Controlling ServoMotor By Using Of Potentiometer In Arduino

Introduction

In this article, I am explaining about  controlling the ServoMotor using Potentiometer in Arduino. In this article, I will control the Servo Motor in the adjustment of Potentiometer. 

 

Parts of the List

• Arduino Uno
• Potentiometer
• Servo Motor
• Bread Board
• Hook up wires 

Connection

Servo Motor

• Connect the Vcc of the Servo Motor to the 5v of the ArduinoUno.
• Connect the gnd of the bluetooth to the Gnd of the ArduinoUno.
• Connect the Vin of the bluetooth to the 09 of the ArduinoUno.

Potentiometer

• Connect as per the preceding figure to the Arduino board and the LCD Display.
• The Vin is connected to the LCD display in 03.

Programming

#include <Servo.h>

const int servo1 = 3;       // first servo
const int servo2 = 10;      // second servo
const int servo3 = 5;       // third servo
const int servo4 = 11;      // fourth servo
const int servo5 = 9;       // fifth servo
const int joyH = 2;        // L/R Parallax Thumbstick
const int joyV = 3;        // U/D Parallax Thumbstick
const int joyX = 4;        // L/R Parallax Thumbstick
const int joyP = 5;        // U/D Parallax Thumbstick
const int potpin = 0;      // O/C potentiometer

int servoVal;           // variable to read the value from the analog pin


Servo myservo1;  // create servo object to control a servo
Servo myservo2;  // create servo object to control a servo
Servo myservo3;  // create servo object to control a servo
Servo myservo4;  // create servo object to control a servo
Servo myservo5;  // create servo object to control a servo
void setup() {

  // Servo
  myservo1.attach(servo1);  // attaches the servo
  myservo2.attach(servo2);  // attaches the servo
  myservo3.attach(servo3);  // attaches the servo
  myservo4.attach(servo4);  // attaches the servo
  myservo5.attach(servo5);  // attaches the servo

  // Inizialize Serial
  Serial.begin(9600);
}


void loop(){

  servoVal = analogRead(potpin);

  servoVal = map(servoVal, 0, 1023, 0, 179);

  myservo5.write(servoVal);

delay(15);
  // Display Joystick values using the serial monitor
    outputJoystick();

    // Read the horizontal joystick value  (value between 0 and 1023)
    servoVal = analogRead(joyH);
    servoVal = map(servoVal, 0, 1023, 0, 180);     // scale it to use it with the servo (result  between 0 and 180)

    myservo2.write(servoVal);                         // sets the servo position according to the scaled value

    // Read the horizontal joystick value  (value between 0 and 1023)
    servoVal = analogRead(joyV);
    servoVal = map(servoVal, 0, 1023, 70, 180);     // scale it to use it with the servo (result between 70 and 180)

    myservo1.write(servoVal);                           // sets the servo position according to the scaled value

    delay(15);                                       // waits for the servo to get there

// Read the horizontal joystick value  (value between 0 and 1023)
    servoVal = analogRead(joyP);
    servoVal = map(servoVal, 0, 1023, 70, 180);     // scale it to use it with the servo (result between 70 and 180)

    myservo4.write(servoVal);                           // sets the servo position according to the scaled value

    delay(15);                                       // waits for the servo to get there
// Read the horizontal joystick value  (value between 0 and 1023)
    servoVal = analogRead(joyX);
    servoVal = map(servoVal, 0, 1023, 70, 180);     // scale it to use it with the servo (result between 70 and 180)

    myservo3.write(servoVal);                           // sets the servo position according to the scaled value

    delay(15);                                       // waits for the servo to get there

}


/**
* Display joystick values
*/
void outputJoystick(){

    Serial.print(analogRead(joyH));
    Serial.print ("---");
    Serial.print(analogRead(joyV));
    Serial.println ("----------------");
    Serial.print(analogRead(joyP));
    Serial.println ("----------------");
    Serial.print(analogRead(joyX));
