/* 
 Stepper Motor Control - one revolution
 
 This program drives a unipolar or bipolar stepper motor. 
 The motor is attached to digital pins 8 - 11 of the Arduino.
 
 The motor should revolve one revolution in one direction, then
 one revolution in the other direction.

#include <StepperAK.h> //use modified stepper library with 1000/0100/0010/0001 magnet firing sequence. Put library in your library folder.

#define gearratio 64 //1:64 gear ratio
const int stepsPerRevolution = 2048;  //the Arduino Kit motor is geared down. By experiment I determined that 2048 steps turn the shaft one round.
                                     

// instantiate a 4-wire stepper on pins 8 through 11:
Stepper myStepper(stepsPerRevolution, 8,9,10,11);            

void setup() {
  // set the speed at 0.15 rpm (0.15-0.2 (dep. on particular motor) seems the fastest they can go...set it higher and it stops moving, just makes noises):
  myStepper.setSpeed(0.15*gearratio);//the motor appears to be geared down 1/64, meaning that the speed needs to be set 64x.
  // initialize the serial port:
  Serial.begin(9600);
}

void loop() {
  // step one revolution  in one direction:
   Serial.println("clockwise");
  myStepper.step(stepsPerRevolution);
  delay(500);
  
   // step one revolution in the other direction:
  Serial.println("counterclockwise");
  myStepper.step(-stepsPerRevolution);
