Arduino led not blinking

Question

#include <Arduino.h>
void setup()
 {
 pinMode(13, OUTPUT);
 }
void loop()
{
 digitalWrite(13, HIGH);
 delay(1);
 digitalWrite(13, LOW);
 delay(1);
}

I am trying to make an led glow for one second to glow and then go off but nothing happens

• Juraj: how did produce a wrong version of the most basic Arduino example? arduino.cc/en/Tutorial/BuiltInExamples/Blink
• the busybee: Your first step when facing such a problem is to read the documentation. You have 3 functions in your code, which as read in a short time, less than 5 minutes. You would have found the delay() expects the interval in milliseconds. Please do so the enxt time.

Answer 1

#include <Arduino.h>
void setup()
 {
 pinMode(13, OUTPUT);
 }
void loop()
{
 digitalWrite(13, HIGH);
 delay(1000);
 digitalWrite(13, LOW);
 delay(1000);
}

The problem with your code is that the delay function works in milliseconds and not seconds . 1sec = 1000ms .

• Juraj: what is next? The "Bare Minimum" example without loop()?
• xbox gamer: True but just go a little easy in the newbie
• DataFiddler: @Juraj: The Bare Minimum Blink (arduino.cc/en/Guide/ArduinoUno#open-your-first-sketch ) works without the line #include <Arduino.h>
• xbox gamer: I use platform io for programing so in that it is important to include arduino.h maybe the person who asked is also using platform io or something similar

Answer 2

by increasing the delay value, you can visualize it better.

{
 digitalWrite(13, HIGH);
 delay(2000);
 digitalWrite(13, LOW);
 delay(1000);
}
