I don't know what language your using, or what micro-controller your using. But I have created a project a while ago that automatically opens / closes my blinds. :D I used an AtMega168 AVR micro-controller, and my code is in C. Basically, it uses the ADC to read how light / dark it is, then decides what to do based on the lightness value.

My Code:

Automatic Blinds Controller Code

Its really simple, once you get the gist of it.

This is an example of going a long way out of your way just to say that "my project uses a microcontroller"

hmm... Microcontroller? Can't you use something like transistor for switching the motor for the blinds or cloth line(?)

Exactly, why not simply use a comparator?
LM311 Light/dark detector/thermostat

The chances are you'll need an h-bridge an limit switches but it's not hard.

Heck, you could use a small SLA and solar panel so the whole thing is solar powered.
