#include <Servo.h>

Servo A;  // create servo object to control a servo
Servo B;           // twelve servo objects can be created on most boards

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

void setup()
{
  B.attach(4);
  A.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
    A.write(pos);              // tell servo to go to position in variable 'pos'
    B.write(pos);
    delay(15);                       // waits 15ms for the servo to reach the position
  }
  for(pos = 180; pos>=0; pos-=1)     // goes from 180 degrees to 0 degrees
  {                              
    A.write(pos);              // tell servo to go to position in variable 'pos'
    B.write(pos);
