I am building a LED sign. I have serries paralleled the LEDs to form letters. What I am trying to accomplish is drive each letter one at a time, then latch it. Ie if I had my name "BILL" laid out in a LED pattern. I want "B" to light up then latch(stay on) then "I" and then "L" and so on. Then once the name has been completley lit up have the whole thing flashes a few times, then resets. I am sure there is an easy way to achieve this, I just can think of one. I dont think i can use a 4017, since the previous pin goes low when the next goes high. Any pointers? I will use npn transistors to switch all the segments. Thanks for the help!
