Hi guys,
i'm new here!
I'm trying to build a lighted gas pedal as in the show (knight rider), a simple circuit to light 14 leds (14 on each side) from bottom to top, as it was a vu-meter, just pushing a button. I don't think it's a hard circuit for who is a good man with electronics. I think this circuit will need a couple of LM3914 or LM3915.
Please, help me in this project!
Thank You
T.N.

led
use a bass filter using a cap and a resistor and then a resistor on on opamp to a counter or something
######____R2___
######| _C1_R1_|

#linein _ |_|\____|__C2_|\_clock

2 op-amps with positive pin grounded play with the values to optain the bass level at which you want the leds to step.
dont know if that works.. worth a try on a proto board
