    What I need is a scematic for a simple photo cell circuit to switch 5 x 5mm led's on, on sundown whitch will be installed on my rc boat.The circuit will be powered by 12v dc. I am a real novice at this, as I have purchased a book Electronics for dummies and have just ordered scematics for dummies.
