Instead of plug a straight iron wire into the pot of potentiometer, he suggested me to bend the wire and inlay it into a horizontal indentation. So it has a anchor point to move and a full control of rotation. I did the same to the other side of wire to connect it with door joint tightly.
I cut the potentiometer to less then 3/4 inch so I can hide it into a step at th bottom of the door case. Now the angel of the potentiometer changes identically with the door angel. And I tested it with my laptop. The angel of this wood ready-made door is only 90 degrees, which made me have to change my original code to show videos completely . But I am thinking how I can make it open wider to let the interaction longer. I also tested it with a led installed in the doorway to add some light while the video switches into a hidden camera view.

This is a ideal view of a mini camera which I haven't plugged into the door way. Now I am using a plug-in cam on my laptop.
Manual, box, eee pc. I am trying to install OF and Arduino into this tiny computer.
Test view. I found that the screen is smaller then my doorway exit. So I have to redo the door way again.
