Stepper Motor Power Supply Just a quick question. Picking up some stepper motors, but confused at what voltage/current things are running off.

Ordering:
2 x Stepper Motor
2 x EasyDriver

An article says


  You need some 12V source to the EasyDriver (the motor in this article
  is 12V) - This will be powering the stepper - Im using a 12V adapter -
  similar to the one in the illustration. Just make sure it is rated at
  least 750ma - A higher rating is better, and just means it wont burn
  out.


So does that mean if I got a plug which is regulated 12V 1A and powered the Arduino from that I could power a rail with VIN pin and that would safely supply the EasyDrivers? And I could then use the 5V pin to power everything else?

Just don't want to break anything! Thanks
Stepper Motor Control - one step at a time

This program drives a unipolar or bipolar stepper motor.
The motor is attached to digital pins 8 - 11 of the Arduino.

The motor will step one step at a time, very slowly. You can use this to test that you've got the four wires of your stepper wired to the correct pins. If wired correctly, all steps should be in the same direction.

Use this also to count the number of steps per revolution of your motor, if you don't know it. Then plug that number into the oneRevolution example to see if you got it right.

#include &lt;Stepper.h&gt;

const int stepsPerRevolution = 200;  // change this to fit the number of steps per revolution
// for your motor
// initialize the stepper library on pins 8 through 11:
Stepper myStepper(stepsPerRevolution, 8, 9, 10, 11);
int stepCount = 0;         // number of steps the motor has taken

void setup() {
    // initialize the serial port:
    Serial.begin(9600);
}

void loop() {
    // step one step:
    myStepper.step(1);
    Serial.print("steps:");
    Serial.println(stepCount);
    stepCount++;
    delay(500);
}
