what pins 11 and 12 (the top and botom switch) are doing? what pins 15 and 13 are doing? how it detects to stop motor (opening/closing)? sorry, not an expert in GPIO :-)
I am a master Tinker ( I always end up over my head ) LOL
Yes on printing open close
Okay pin 11 & 12 are magnetic door switches (which I may change to Micros)
when photo module shows change ( night day ) the motor runs to open close door the magnetic switch is stop point.
Pins 13 and 15 goes to a small motor controller they are what control's direction of motor ( up & down for door)

OK, I entertain the idea of buying RPi for a log time so this is also interesting to me.
I did some raeding on GPIO, so please confirm if my understanding is correct:
when pin is IN, you get information from it, when it is OUT - you send info to whatever is connected. When HIGH it is powered.
- pin7 is light sensor. When it is LOW (False) - there is light, when it is HIGH (True) - there is no light detected.
- pin 11 and 12 are switches that detect the door is open/closed. When respective switch is HIGH (true) the door is already
open/closed. i.e. while the door is open switch 11 is non-stop powered and in state HIGH
- 15 and 13 are motors. 15 drives the motor to open the door. 13 powers the motor to close it. I don't know if the same motor with different direction of movement or different motors driving in one direction only. I guess 2 motors, because when pin 11 is HIGH, you actually sending non-stop info to pin 15 to stay LOW (False).
Is that correct. Please correct me if not.
Also, if you set OUT pin HIGH, it stays so, until set LOW, right?
I'm no expert but you are correct to my understanding pins 11 and 12 are to stop motor at set point Door open door close.
pins 13 and 15 control motor (small DC car window winder) I am running them into a IDUINO L298N Motor Driver Controller Board which takes care of the up and down from pin 13 and 15 it reverses the polarity out to motor
