Delay Motor Problem & Controlling 2 Motors are different speed.

hello,

i have problem servo motor. using arduino uno, , towerpro mg995 servo motor. motor starter kit. using sweep example code arduino , reason when changed delay 15ms 1000ms, servo no longer runs 0 180 , reverse. goes angle , gets stuck @ point. changed delay in code , nothing else.

here code:

// sweep
// barragan <http://barraganstudio.com>
// example code in public domain.


#include <servo.h>

servo myservo;  // create servo object control servo
               // maximum of 8 servo objects can created

int pos = 0;    // variable store servo position

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


void loop()
{
 for(pos = 0; pos < 180; pos += 1)  // goes 0 degrees 180 degrees
 {                                  // in steps of 1 degree
   myservo.write(pos);              // tell servo go position in variable 'pos'
   delay(15);                       // waits 15ms servo reach position
 }
 for(pos = 180; pos>=1; pos-=1)     // goes 180 degrees 0 degrees
 {                                
   myservo.write(pos);              // tell servo go position in variable 'pos'
   delay(15);                       // waits 15ms servo reach position
 }
}


in code changed delay(15) delay(1000).






also, wondering how can change code make 2 motors run @ different speeds. code after awhile start run @ same speed. not want. want myservo1 run 20 degrees ahead of myservo2 every position (degree). here code:

#include <servo.h>

servo myservo0, myservo1;

int pos = 0;

void setup()
{
 myservo0.attach(9);
 myservo1.attach( 8 );
}//setup

void loop()
{
 for(pos = 0; pos < 180; pos += 1)
 {
   myservo0.write(pos);
   myservo1.write(pos + 20);
   delay(10);
 }//for
 
 for(pos = 180; pos >= 1; pos -= 1)
 {
   myservo0.write(pos);
   myservo1.write(pos + 20);
   delay(10);
 }//for
}//loop
   

take both delays out of loops , put them right after loops.
