turn on a led

hello, I have the arbotix robocontroller and here is a picture of the led that I putted on the digital port: http://postimage.org/image/kl11gr27v/ and i want to turn on this led what sould i write at arduino to do this?

Is this an Arduino clone ?

First have a look at the sticky http://arduino.cc/forum/index.php/topic,97455.0.html

and some notes about LEDs


Then look at the example for "blink" and work from there through the examples.
