28BYJ-48 5-Volt Stepper

OK, got it. probably had to do with the pin definition

// accellsteppertest.ino
// Runs two steppers forwards and backwards, accelerating and decelerating
// at the limits. Derived from example code by Mike McCauley
// modified by Celem for single stepper
// Set for two 28BYJ-48 stepper motors

#include <AccelStepper.h>

#define FULLSTEP 4
#define HALFSTEP 8

//declare variables for the motor pins
int motorPin1 = 4;	// Blue   - 28BYJ48 pin 1
int motorPin2 = 5;	// Pink   - 28BYJ48 pin 2
int motorPin3 = 6;	// Yellow - 28BYJ48 pin 3
int motorPin4 = 7;	// Orange - 28BYJ48 pin 4
                        // Red    - 28BYJ48 pin 5 (VCC)
int motorPin5 = 8;	// Blue   - 28BYJ48 pin 1
int motorPin6 = 9;	// Pink   - 28BYJ48 pin 2
int motorPin7 = 10;	// Yellow - 28BYJ48 pin 3
int motorPin8 = 11;	// Orange - 28BYJ48 pin 4
                        // Red    - 28BYJ48 pin 5 (VCC)
// The sequence 1-3-2-4 required for proper sequencing of 28BYJ48
