I want to use a Light Dependent Resistor (LDR) to control a door ( open when it feel light and close it when it's darkness).

What kind of signal does the door actuator require? Do you need to drive a motor?

Yes, if it's light the motor will open the door and when it's night (darkness) the motor will close the door.

I need a help seriously

Indeed, probably with both software and hardware. If you don't have any experience in these areas why were you chosen to implement such a design? What design and implementation skills are you bringing to the project?

You are describing top level functionality, the question I asked related to the nature of the signal the door actuator required, not why it was driven.

Very good questions!
