Twinkle twinkle litle LED

This is a project form "Getting Started with Arduíno", or at least the main idea was from there.
The goal is to make a LED blink according to the light.

This is what it will look like:


Components:
1 Arduino Duemilanove
1 breadboard
1 LDR
1 Resistence of 10 k ohms +/- 5%
3 wires
1 USB/Arduino cable
1 computer

This is my pseudo-schematic:


Here is my code for this project:

// Light sensitive LED

int val = 0;

void setup(){
pinMode(13, OUTPUT);
}

void loop(){
val = analogRead(0);

digitalWrite(13, HIGH);
delay(val);

digitalWrite(13, LOW);
delay(val);
}

If all goes well you should end up you a project looking like this:
