Okay someone tell me if they think this will work. Let's say for example that I want the #2 light switched off, this would mean I need the chip to go to light #3. TO do this what if I used a dpdt switch to not just turn #2 off but to reroute it so that it will trigger some kind of pulser. the pulser would then be connected to the input switch of the chip via n.c. relay. this would then open up the input to the chip and then close it causing the chip to move to #3. Let me try to explain it again I push the button to switch to #2. The signal goes out of #2 output and to a pulser, this pulser would then trigger the realy to open up and after the pulser is done release the realy thus closing the circuit causing the chip to move to the next (#3) light. The relay actually does the same thing as the push button I have controlling the chip.

can you tell me more about digital gates, I have no idea what they even are.

Let me be a bit more detailed. I don't always explain everything real clear. I need 8 leds that light up in sequence. I want to run the switching from one light to the next with a push button instead of the common 555 timer, but I got that part conquered. Where I am having trouble is say for example that light 4 is turned on, now what I might need to do is to flip a switch at this moment that will "block" light 2 from turning on. If I press the push button light 4 will go off and light 5 will come on just like normal no big deal, but at the end of the sequence (light 8) it needs to go back to light #1, no problem there yet. Now Light 1 is on, remember that light 2 is "blocked" or turned off, with the next press of the button I need it to turn light 3 on. In other words, skip over the lights that I have turned off, like they were never in the sequence to begin with. Maybe this is a little clearer. And thanks for all trying to help.

Say for example that the #2 light is shut off. I need the chip to automatically go to #3. Further more if #2 and #3 are shut off then I need it to automatically turn on 4.

I am needing an LED sequencer that has the ability of turning off (by switch) any of the lights and behaving just like the one or ones turnd off where never there. Can anyone steer me in the right direction?

I would love it.

I am trying to make a project that would consist of 12 led's. At a given time I would need 3 of these lights lit spcifically 1, 5 and 9. after the press of a button I would need lights 4,8,and 10 lit. this continues on and on with different sequences. Anyway the exact numbers are not importoant to you but this is the type of setup I am needing can someone please point me in the right direction as I have no idea which direction I shoud start going. I have a basic understanding of electronics. Thanks, esaunders
