    Hello everyone.
    I have a project that I wan't to use 10 leds lined up in a row.
    Basically 10 of them,with a switch up and down switch,so i can get the first one lighted,and hit the up switch to go to the next led.
    What would be the sequence of this to follow?
    Thanks,Scotty

    Is there a thread that would tell me how to connect them,and what extra i need to make them light up one at a time?I know I need 10 leds,and a switch to toggle between them.

    10 LED's, Probably 10 Switches.
    Or use an LM3914 Driver and a Single Potentiometer to adjust input Voltage.

    Going by your avatar, is this project intended as a an indicator for effects pedals?

    No it is for a scoring game,so using leds to go up to 10.
    Ok,thanks on the other answer.

    You could get the up and down counting done with a bunch of logic ICs, but it would be rather messy. The obvious alternative would be a suitably programmed MCU (Arduino, PIC, what have you).

    You can manually clock an up/down decade counter such as a 4029 or 4192 using a debounced momentary switch and an up/down select switch. You could probably do it with a single 3-position momentary switch but it would require a bit more circuitry to delay the clock pulse until the direction was set. You probably need to include a reset or clear function as well.
