Flower drawing on a single circuit.

Code:

int ledPins[] = {0,1,2,3,4};

int led = 13;

void setup()

{

  int index;

for(index = 0; index <= 4; index++)

  {

    pinMode(ledPins[index],OUTPUT);

}

void oneOnAtATime()

{

  int index;

  int delayTime = 100; // milliseconds to pause between LEDs

                       // make this smaller for faster switching

  

  // step through the LEDs, from 0 to 4

  

  for(index = 0; index <= 4; index++)

  {

    digitalWrite(ledPins[index], HIGH);  // turn LED on

    delay(delayTime);                    // pause to slow down

    digitalWrite(led, HIGH);  // turn LED on

    digitalWrite(ledPins[index], LOW);   // turn LED off

  }

}
