    Hi,

    I have a lightning detector from STORMWISE. The detector puts out a
    pulsed DC signal.The recieve end is a led or piezo alarm for each
    lightning stroke. I want to display the signal useing a LM3914 Dot/Bar
    display driver to 10 leds.

    Do I need to add anything between the detector & the LM3914 to change
    the pulsed DC?

    I was told to put a 1:1 isolation transformer between-but dont know if
    this is correct.

    Any help would great.
    Thanks,Kim
