Wiring Diagram

Only PWM interface could control the Servo.

Other Preparation Work

Open Arduino IDE, select Tools --> Board --> Intel Edison and Tools --> Serial Port --> COM xx.

Sample Code

Import Servo lib, attach to pin9, cycle servo rotation back and forth.

#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

void setup()
{
  myservo.attach(9);  // attaches the servo on pin 9 to the servo object
}

void loop()
{
  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
  }
}

Result

The servo motor rotates from 0° to 180° and then back to 0° repeatedly.
