newbie trying to program led chaser using relay

hi there,

i got thrown arduino project yesterday.

here our hardware:
- arduino duemilanove atmega328
- electronic brick shield pro (extended com digital com ports)
- simple  relay


what trying accomplish 3 led chaser using 3 relays control chaser.

the problem having in code lights go in sequence stay on until loop ends oppose led1 blink on/off -- led2 blink on/off --- led3 blink on/off

if try use delay or change time interval lights stay on longer.

here code tried use below:
-------------------------------------------------------------------------

/* blink multiple leds without delay
*
* turns on , off several light emitting diode(led) connected digital
* pin, without using delay() function.  this means other code
* can run @ same time without being interrupted led code.
*/
int led1 = 0;                // led connected digital pin 13
int led2 = 3;
int led3 = 7;
int value1 = low;                // previous value of led
int value2 = low;
int value3 = low;                           // previous value of led
long time1 = millis();
long time2 = millis();
long time3 = millis();

long interval1 = 500;                  // interval @ blink (milliseconds)
long interval2 = 500;
long interval3 = 500;

void setup()
{
pinmode(led1, output);      // sets digital pin output
pinmode(led2, output);
pinmode(led3, output);
}

void loop()
{
unsigned long m = millis();

if (m - time1 > interval1){
  time1 = m;

  if (value1 == low)
    value1 = high;
  else
    value1 = low;

  digitalwrite(led1, value1);
  delay(500);
}

if (m - time2 > interval2){
  time2 = m;

  if (value2 == low)
    value2 = high;
  else
    value2 = low;

  digitalwrite(led2, value2);
  delay(1000);
}

 if (m - time3 > interval3){
  time3 = m;

  if (value3 == low)
    value3 = high;
  else
    value3 = low;

  digitalwrite(led3, value3);
 
}
}


-------------------------------------------------

any appreciated!

thx!

code: [select]

int led1 = 0;                // led connected digital pin 13
well, it? led connected pin 0 or pin 13? it's not idea use pin 0 unless absolutely necessary, 1 of serial port pins.

stop using that, , use can use serial.begin() in setup , serial.print() in loop() see happening.

using millis() determine when toggle pin great idea. using delay, too, not.
