What is wrong is that it does not work.

I suspect that nobody can help unless you show the code you are actually using and explain exactly how you have wired up your LED.

Might help to mention exact Raspi model and operating system version as well.

My suspicion is that if you had followed the instructions you have linked to correctly then it would work.

Is your LED the right way around for example?

#include <wiringPi.h>
int main (void)
{
  wiringPiSetup () ;
  pinMode (0, OUTPUT) ;
  for (;;)
  {
    digitalWrite (0, HIGH) ; delay (500) ;
    digitalWrite (0,  LOW) ; delay (500) ;
  }

hi,
Does wiringPi work correctly? What happens if you type in the console
gpio -v
gpio readall
?
Did you check if you really had connected to GPIO 0 and not to a different neighbor pin?
Is the LED connected correctly? does the LED turn on if you disconnect the wire to GPIO 0 and then connect to +3.3V?

Works fine for me - have you tried turning the LED around. Post an actual photo of your wiring.

Take look at wiring

You have the red wire on pin 6 which is ground.

Which is very confusing.

Are you sure that LED is the right way around?
