[Prabakaran P M]

Hi, You can use this code,

 

int led=13,ledstate;

 

int previous=0;

 

int interval=2000;

boolean toggle = false;

 

void setup()

 

{

 

pinMode(led,OUTPUT);

 

}

 

void loop ()

 

{

 

int current=millis();

 

if(current – previous>=interval)

 

{

 

previous=current;

 

  toggle = !toggle;

  digitalWrite(13,toggle);

 

}

}
