Lego Castle & Arduino :)

I just build a little Lego castle and then suddenly decided to bring more life to it with an Arduino! The end product made a real nice little night light :)

Just pay attention that in the schematics and code, I have only added two LEDs; but in the actual project I have used six. Each LED should be connected to a PWM port on Arduino so the flickering effect can be applied (therefore 6 is maximum).
