I am building a circuit so that when it gets dark I have 8 LED's come on. I Bought a five pack of 5 Cadmium-Sulfide Photocells from RadioShack (part # 276-1657). So I have a battery pack that runs to the switch that runs to a photocell that runs to the LEDs that connect back to the battery pack. But the problem is the LEDs come on in the light, how can I make them come on in darkness? My circuit looks like the attached picture.
