Capacitor Circuit to smooth out LED music controller?

[sputnik516]

I have a controller that makes LEDs (or anything else connected to it) flash to the music. However, when working, the LEDs go on and off. I wanted to build a capacitor circuit to make them fade out. The (+) output on the controller is a constant 12V and the (-) switches on and off. How would I build the circuit?

Hi, and welcome to the forum!

The most basic way would be to put a capacitor in parallel with the LED and its resistor, but that will make the LED fade on and off, not just off (which I think is what you want).

There are a few ways to do this. If you post your schematic it will be much easier to help you, though. Post the circuit and we'll be better able to tell you what the simplest solution might be.


Good luck!

Thats basicly it. The 4 LED's in parallel need a resistor but seem to work fine without one. I can get the current drawn by all the lights if necessary (it's 2:20 am, not about to go outside with a multimeter), but I know it came with a 6 amp fuse.

Also, like I said before, the (-) of the controller output switches on and off, the (+) stays on.
