I am looking to make a circuit that is either a variable rate from 1-10 flashes per second or 8 flashes a second exactly. I need it to be like the police lighst they now have. In a sequence like (l=left r=right) LLLLLLLL, RRRRRRRR and so on continously. I would like for the circuit to be able to hold about 10-15 LEDs on each leg (left and right). I am fairly knowledgeable with small electronics so Can gents help me? Thank you
