title: Changing stepper Motor speed
body: <p>I have stepper motor, that I want to control his speed. How is it possible? </p>
  
  <p>I am using an Arduino UNO.</p>
  
  <pre><code>for (i = 0; i&lt;400; i++)       // Iterate for 4000 microsteps
  {
      digitalWrite(StepPinB, LOW);  // This LOW to HIGH change is what creates the
      digitalWrite(StepPinB, HIGH); // "Rising Edge" so the easydriver knows to    when to step.
      delayMicroseconds(500);     
  }
  </code></pre>
