Being a new chicken "farmer", I have been looking for a way to automate my new chicken coop. First, I installed an automatic water and feeder using 4" septic PVC pipe and a couple of elbows and a "Y" connection. How to make them is all over "Pinterest". My next task was to come up with a way to automate the chicken door. Again, there are many methods on "Pinterest" and the one that I liked the most was using an automatic car antenna. There were a bunch of posts showing how it worked, and a few that showed a bunch of wiring hooked up. But none that I could find actually showed how to wire up the battery, solar panel, solar controller, photo cell, and the antenna. After a few attempts, I was finally able to figure out to how wire everything up. I don't have a picture of the coop door with everything working, but what I do have is a wiring diagram that will make it an easy task if you want to go with an automatic opener.
