No Blinking LED

I've gotten all the installation to work ( I think) using a UNO board and the starter kit. I am trying the first example making an LED blink, and not getting this to occur. Connections and hardware are in place as reqested by instructions, and the small light on the Uno board will blink at a steady rate matching the speed of the delay in the sketch, but I dont get any blink to the LED on the breadboard. I've swapped out each wire, LED and resistor, reversed them, and been systematic, but am not getting a response from the item placed in the breadboard. Any suggestions?

void setup ()
{
  Serial.begin (9600);
  Serial.println (F("Hello world"));
}

void loop ()
{
}
}

Do you get anything in the serial monitor?
(having set the correct baud rate)

Oops.... extra } at the end of AWOL's code there...

void loop ()
{
}
}<<<<<<<<<< you need to zap this one

Might be an idea to post a photo of your breadboard setup....

One test might be to stick the LED anode into pin 13's hole, the resistor into GND next door to it, twist the resistor to the LED cathode. See if that works.... that will take wires and breadboard out of it.

Oops - thanks.
