    Hi everyone. I'm wanting to learn about the PIC chip so
    I thought I would start with a simple? project.

    I'm looking for a how to on building a "fill up" light.
    I would like to use three 10 bar LEDs (see parts list below)
    and have each bar light, and remain on, from 1 to 30 with a
    one {adjustable} second delay between each light. When #30 has
    been energized there is a two {adjustable} second delay and the
    process starts all over again. (maybe 1 second after 30
    lights up I could beep a buzzer?)

    This will be used as a timer for a project where you
    need to answer a question before the lights go out.

    I have an old bread board, PIC16F688, a PICkit2 and some other
    donated stuff, could someone point me to information on how to
    do this?

    Thank you.
