I've racked my brain to come up with a simple 12VDC circuit to determine which strand of LED ribbon to turn on.
Here's the plan:
When here is ambient light (day time) and I open a door (reed switch) the High Output LED strand is turned on.
When there is low light and door is opened, the red strand is turned on.
I see using a photo resistor circuit, but the OR gate logic eludes me.
Thank you for your time.
