I have designed this simple dark sensor circuit that will turn on some LEDs at nightfall. After testing, it seems to be too sensitive, meaning it takes a fair amount of light to turn the circuit OFF. This would allow the lights to illuminate well before sunset and to keep working further into the morning. Even sitting on my kitchen table with a light on above, it does does not turn the led off. I have to add a brighter light. And then, just a shadow from my hand will turn it on.
My question is, how can I adjust the sensitivity to require much less light to turn the circuit off? I'm assuming an adjustment to my resistor combination would do it, but not sure..... thanks.
P.S. the system is 12v DC
