Hi, my coworker and I built an automated chicken door for our chicken coop. We are using an Arduino Uno, though not genuine, an RTC (DS-3231) and two reed switches. The arduino is being powered by a 12v ps and that power is divided between the arduino and the motor, there is also a battery connected to the motor to give it some more juice and hopefully make sure there is no flicker (Not sure it works though). It gets really cold here at night but the arduino is also responsible for switching on a heat lamp and a light so it doesn't get below freezing in the coop.
Our problem is that everything will work perfectly for a few days and then something goes wrong, the door will either stay up or stay down. We wrote in a default position so if the door is ever confused it will just go down and reset the loop, but that doesn't seem to be working either.
If someone could read through our code that would be a great help as we are both newish to the arduino realm. I cannot decide if it is a power/flicker problem or something in the code. I live on the farm but would like to have this set up so I don't have to check on it every night/ morning and when no one is here it would be nice to know the chickens are ok. I have the code attached, it is tabbed so all 6 files are needed and I posted it here as well. Your help is greatly appreciated.
