  // set stepp[er to 180 rpm, CCW, with acceleration and deceleration
  stepper.rpm(180).direction(Stepper.DIRECTION.CCW).accel(1600).decel(1600);
  
  // make 10 full revolutions 
  stepper.step(2000, () => {
    console.log("done moving CCW");

    // once first movement is done, make 10 revolutions clockwise at previously
    //      defined speed, accel, and decel by passing an object into stepper.step
    stepper.step({
      steps: 2000,
      direction: Stepper.DIRECTION.CW
