Hopefully I’m in the right place. I have zero background in electronics so forgive my ignorance here. Over a year or so I’ve made a circuit that includes a photocell, motion sensor, relays, transistors (for darlington effect) voltage reducing board. The board is to turn on and off as the sun rises and falls. At night it powers led strips (30’ ish) but only at half power. When a pir triggers, the lights go to full power for the set time in the pir and drops back to half power and continues to work that way until the sun comes up. I’ve made several of these boards but seem to run in to a different problem with each. It works great on a breadboard. I use a laptop power supply to run all of it. I’d like to simplify the board to say a 555 or something else that will work but, again, I have no idea where to start.
