#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 .

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 Commented Oct 28, 2020 at 22:05
by increasing the delay value, you can visualize it better.
{
digitalWrite(13, HIGH);
delay(2000);
digitalWrite(13, LOW);
delay(1000);
}
delay()expects the interval in milliseconds. Please do so the enxt time.
