Automatic Solar Dog Door Opener
So I want to attached a solar powered device that would open when he is near by.
I imagine I would mount it above the black bar, outsize where the is light with the solar panel wedge, attached to the door (see image uploaded).
I don't really know how to go about it.
The major components would be:
1. Solar panel wedge and batter (power source)
2. Proximity sensor (maybe RFID attached to my dogs collar?)
3. Motor (not sure how to detect when the door is opened or closed. etc etc
How does one go about building something like this? Any direction would be great
