Part 2 in my experiment building a fully automatic chicken coop door. Although it seems like nothing got accomplished, figuring out the DPDT relay was a big step forward. Now all I need is a working light sensor or timer.
I should have everything working properly and installed next week. If you have any ideas as to why it kept opening and closing intermittently, please let me know in the comments.
