It’s ALIVE!!! I finally got my DIY automatic chicken coop door working, and temporarily installed. I used a power antenna motor to drive the door on cabinet drawer slides. The whole unit is solar powered by a 12 volt battery.
I used a DC timer and DPDT relay to trigger the opening and closing of the door. In the video, I put all of the components in a nice plastic enclosure that hides most of the wires.
It worked perfectly, closing at sunset and opening at sunrise!
Here’s a link to the wiring diagram:?https://goo.gl/hGL0GZ
