>hey, who wrote this article?

I wrote it but forgot to attribute it to myself. Here's a little Arduino script that improves on the basic blink application, I expect to do more serious projects with this cool device.

/*
 * Blink2
 * based on the blink example:
 * http://www.arduino.cc/en/Tutorial/Blink
 * Now the LED blink rate changes from fast to slow and back.
 */

int ledPin = 13;                // LED connected to digital pin 13
int dtime = 40;
int flip = 0;

void setup()                    // run once, when the sketch starts
{
  pinMode(ledPin, OUTPUT);      // sets the digital pin as output
}

void loop()                     // run over and over again
{
  if (flip == 0)
  {
    oneblink();
    dtime += 10;
    if (dtime >= 180)
     flip = 1;
  }
  else
  {
    oneblink();
    dtime -= 10;
    if (dtime <= 40)
     flip = 0;
  }
}

void oneblink()
{
  digitalWrite(ledPin, HIGH);
  delay(dtime);
  digitalWrite(ledPin, LOW);
  delay(dtime);
}
