Its late, I cant think straight, please help...
after several failed attempts to build a simple LDR circuit to turn on series of LED's at night, I gave up and spent 10 bucks on a KEMO 12v light barrier kit, which can be used as a twilight sensor - I built it, no worries. The only problem is now I have a cute little board that I don't know how to use or how connect my LED's to it.
There is a '+' and a '-' on the kit's board for what I assume is where my battery will go into, but the only 2 little holes in the PCB other then that are near the Relay labeled 'S' and 'P' - Is that where my bank of LED's goes (+-)?
The LED circuit that I built is simply a 120 Ohms resister for 3 super-bright LED's (I will eventually have more of these to get 18 LEDs in total) - that works fine on its own with 12V's, I figured it would be easy enough to put this Kemo twilight sensor in between the battery and the LED's and Abra-Kadabra the lights come on at night)
Im very new to this any help would be greatly appreciated.
