i need some help to solve my problem.

how to stop led ON after 5 times?

this is my code

void setup() {

pinMode(18, OUTPUT);

}

void loop() {

digitalWrite(18, HIGH); // turn the LED on

delay(1000); // wait for a second

digitalWrite(18, LOW); // turn the LED off

delay(1000); // wait for a second

}

First welcome to the forum. Second before any one mentions it they would like you to use code tags. What is a code tag? At the top of you screen you will see </> This is a code tag. the easiest way to use it is copy your sketch click on the code tag Paste you sketch between the <> symbols. It is that simple.

By the way I do not see a counting routine in your code to count to 5.

Hi,

Welcome to the forum.

Please read the first post in any forum entitled how to use this forum.

then look down to item #7 about how to post your code.
It will be formatted in a scrolling window that makes it easier to read.

What model arduino are you using?

Thanks .. Tom... :slight_smile:

Move it into a for:loop in setup():

byte count ;
void setup() {

  pinMode(18, OUTPUT);

 for (count = 0; count <5; count = count +1){
  
   digitalWrite(18, HIGH);   // turn the LED on 

   delay(1000);              // wait for a second

   digitalWrite(18, LOW);    // turn the LED off 

  delay(1000);              // wait for a second
 }
}

void loop() {
}
