  Sweep
  by BARRAGAN <http://barraganstudio.com> 
  Adapted by Philip van Allen <philvanallen.com> for the VarSpeedServo.h library (October 2013)
  This example code is in the public domain
  
  Sweep a servo back and forth from 0-180 degrees, 180-0 degrees
  Uses the wait feature of the 2013 version of VarSpeedServo to stop the code until the servo finishes moving
  
  Note that servos usually require more power than is available from the USB port - use an external power supply!

  myservo.write(0,30,true);           // move the servo to 180, slow speed, wait until done
