Arduino USB Control Servo Motor

Arduino USB Control Servo Motor

Use Arduino Board to control Servo Motor.

Hardware

1. Arduino Board or compatible Board.

2. USB Cable ( A to B Male/Male )

3. Servo Motor ( We use FUTABA Model S3003 or other)

Wiring Diagram

Use Arduino PWM Output pin 9

 #include <Servo.h>

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

                // a maximum of eight servo objects can be created

int pos = 0;    // variable to store the servo position

int motor = 0;

void setup()

{  

  Serial.begin(9600);  // initialize serial: 

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

 

  Serial.print("Arduino control Servo Motor Connected OK");

  Serial.print('\n');

}

void loop()

{ 

  // if there's any serial available, read it:

  while(Serial.available() > 0) {

    

    // look for the next valid integer in the incoming serial stream:

    motor = Serial.parseInt();

   

    // do it again:

    pos = Serial.parseInt();

  

    // look for the newline. That's the end of your  sentence:

    if (Serial.read() == '\n') {

              

       myservo.write(pos);              // tell servo to go to position in variable 'pos'

       delay(15);                       // waits 15ms for the servo to reach the position

     

      // print the three numbers in one string as hexadecimal:

      Serial.print("Data Response : ");

      Serial.print(motor, DEC);

      Serial.print(pos, DEC);

      

    }

  }

}

 

  //for(pos = 0; pos < 180; pos += 1)  // goes from 0 degrees to 180 degrees

  //{                                  // in steps of 1 degree

  //  myservo.write(pos);              // tell servo to go to position in variable 'pos'

  //  delay(15);                       // waits 15ms for the servo to reach the position

  //}

  //for(pos = 180; pos>=1; pos-=1)     // goes from 180 degrees to 0 degrees

  //{                                

  //  myservo.write(pos);              // tell servo to go to position in variable 'pos'

  //  delay(15);                       // waits 15ms for the servo to reach the position

  //}

 

 

  //val = analogRead(potpin);            // reads the value of the potentiometer (value between 0 and 1023)

  //val = map(val, 0, 1023, 0, 179);     // scale it to use it with the servo (value between 0 and 180)

  //myservo.write(val);                  // sets the servo position according to the scaled value

  //delay(15);
