A Step-Up from Servo to Stepper Motors

Hi guys, Jagerynn here. Today I will be attempting to set up a stepper motor.

This is the code that I got from the example itself. I will be modifying it and also explaining what some parts mean. My own comments will be written in Italics to differentiate them from the original comments.

[code]
/*
 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 <Stepper.h> //this is the library we are retrieving from
const int stepsPerRevolution = 200;  // const int means constant integer. A good explanation can be found on http://duramecho.com/ComputerInformation/WhyHowCppConst.html but basically it is a variable (constant) that cannot be altered by the program. change this to fit the number of steps per revolution
// for your motor. each revolution is divided into a number of steps. Check the number of steps in your servomotor.
// initialize the stepper library on pins 8 through 11:
Stepper myStepper(stepsPerRevolution, 8, 9, 10, 11);
void setup() {
  // set the speed at 60 rpm:
  myStepper.setSpeed(60);
  // initialize the serial port:
  Serial.begin(9600);
}0
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);
  delay(500);
}
[/code]


As for the wiring, I used this: https://www.youtube.com/watch?v=hZNF7tAJmfk
