    the lm3916 is slightly messed up the program did not have 18 pin chip

    this is two halfs of my project

    induvidually the both work but
    joining together im having problems

    when nothing is connectted to pin 5 all leds are on
    when pin 5 is connect to ground all led are off
    when pin 5 is connected to top half of the output pins (one above capacitor) all leds are on
    when pin 5 is connected to bottom of output pins below cap all leds off

    when a 20k resistor is attached to pin 5 to ground
    when nothing is connectted to pin 5 all leds are off
    when pin 5 is connect to ground all led are off
    when pin 5 is connected to top half of the output pins (one above capacitor) all leds are on
    when pin 5 is connected to bottom of output pins below cap all leds off

    what do you mean

    do you mean this sentence
    can someone guide me in the correct direction to get this thing working

    by that i mean when pin 5 is connected somehow to microphone and amplifier
    when there is silence all leds are off
    and when there is noise the lights bounce up and down
