    Hello forum. I had a qick question about a project I'm thinking of doing.

    So I wanted to make a poker table. I know how I'm going to do that, but I wanted to make a built-in dealer chip. So I was planning to put 8 LEDs (One for each station/person) And at one station there would be an Push button. I want one LED to be lit up at a time, and when the button is pushed, I want the power to transfer to the LED to the right of where it previously was. Again: I only want ONE LED to by lit at a time.

    I'll include a basic pitcure for a visual.

    I think I'll need a demultiplexer and a counter, but not too sure how to use them.


    thanks,
    Jusstice

    Just use a push button instead of an oscillator.

    A 4017 has 1 of 10 outputs on, pretty much exactly as you described. A 4022 does 1 of 8 outputs. It is much simpler than you anticipated.

    I have fair idea of what you are saying, but still unsure. I'm just getting into circuits and not sure how to use a 4017/4022.

    Do you think a multi contact rotary switch would work to? That woul be easy.

    Did you try reading the link I gave? It starts with an LED tutorial. The section has schematics.

    You could use a rotary switch, but you said push button. I've given you everything you need for a push button version. If you have questions about the schematics in the link, ask.
