Im trying to have a fading led that only turn on when there is no light sensed by a solar panel that would probably be attached to an Analog Input. I'm trying to figure it out but I just can't seem to find a way to make it work. I also need to figure out how I'm supposed to plug a solar pa...

I have the basic idea down but I was wondering if I should use servos or stepper motors. My biggest concern is that when I stop the motor turning at any given angle, It won't rotate back down due to gravity. I am using arduino to process and a j...
