Hi all. I found this sketch on a website and have been using it to open and close my hen house door. It is working fine but I would like to add an override switch to open the door when its dark for when the hens forget to go in, and also to keep the door closed when its light etc.
I am a complete newbie with the Arduino and have been trying to add/modify the code to do this but with no success.
Can someone please help me.
I have attached the sketch.
