Hello all, I have been meaning to share this project as it came together, but now I am at a good stopping point to document what I have done to date. I made a little YouTube video (). The upshot is: -rain barrel hooked up to chicken nipples for continual hands-off water. -small attic fan with thermostat to cool the house when when it gets hot. -Light sensor that triggers doors closing at night -Feed level sensor tied to a small servo to display feed level on an old-fashioned dual -a stained glass rooster with LED backlighting to indicate the birds are safely closed in. Happy to provide more technical details for anyone who is interested.
