Post Knight Rider Gas Pedal Reply with quote
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.

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
