Hello,
So I have this idea for a little project but I'm having a problem. So what I want to do is a gizmo that points towards the brightest spot in a room, think of it as a sunflower. I'm not surehow to go about doing this; furtheremore, I don't want to use a microprocessor, ICs only. let me explain.
I was thinking of having a photoresistor attached to a motor so it spins around the room once to find the least resistance then spins again and sits there. The problem is if I move the sunflower to another room I'd need it to be able to spin and realize it has moved.
Another idea is that I arbitrarily set a certain resistance value and have the sunflower turn till it finds that value in the room. The problem with that is if it finds a bright spot that is not the brightest spot.
I am open to any open-ended idea and specifics are welcome too.
thanks in advance.
