I am building some shutters that will be connected to a barn door rail and I want to close them when the sun hits the window in the late afternoon and then opens them back at sunset.
Has anyone done this? I figure the micro controller will be enough to flip the switch to activate the actuators, but have some questions on a few issues.
1) what type of actuators to use? I don't want to burn out motors since the shutters will be pretty heavy (9' x 2.5' each with a 30"+ Stroke). Any brands that have a cutoff when stuck?
2) Temperature sensor or light meter? Which is more reliable? I don't mind the sun when it is cool, but it melts you when it's hot.
Any ideas welcome!
