28BYJ-48 Stepper - run backwards?

using 28byj-48 stepper motor, using stepper.h library in ide 1.8.0 can forward (cw) rotation. see photo attached. sketch comes direct examples>stepper>stepper_onerevolution, on pins 6,7,8,9 no need repeat here.

then went forum , saw other experimenters have had same problem ccw rotation. don't understand if unique problem stepper, or if other steppers exhibit similar issues. seems basic code simple, library not provide proper control.

one of threads suggested using accelstepper.h, downloaded along suggested sketch. although see nothing suggesting ccw operation.

#include <accelstepper.h>

// define steppers , pins use
accelstepper stepper1(5, 6, 7, 8, 9);
// first argument '5' indicates we're using 28byj-48 geared motor. rest pin numbers.
//you can still use other types of motors supported accelstepper library (e.g. 4 normal 4 wire step motor, 8 halfstepped normal 4 wire motor etc.)
accelstepper stepper2(5, 6, 7, 8, 9);

void setup() { 
 stepper1.setmaxspeed(900.0); //max speed of first motor - modify if want to
 stepper1.setacceleration(700.0); // rate @ first motor accelerate -

 stepper2.setmaxspeed(700.0);
 stepper2.setacceleration(400.0);
}

void loop() {   

 if (stepper1.distancetogo() == 0){
   stepper1.moveto(random(1500,7000));//just easy way motors move random positions
 }
 if (stepper2.distancetogo() == 0){
   stepper2.moveto(random(1500,7000));
 }
 stepper1.run();
 stepper2.run();
}

no stepper movement @ all. i've tried changing speed , acceleration no effect. so, @ loss of try next. doesn't seem should difficult. have easy, surefire fix? in advance.

hi,
see page code example know works both directions.

also connections shown there. suspect not have 4 wires in correct (non-obvious) sequence.
