    ok so I'm in the middle of making a lamp thing.
    and here's a picture of it lit
    So inside each of the "bulbs" is 12 LEDs wired up in this rough circuit
    so it's a shared ground with 2 input channels, I'm going to make a 5th light for the topper and will have it be all 4 colors with 4 separate channels. so I've soldered each "bulb" into a stereo jack just to make it easy to work with and swap control circuitry. I am unable to rewire the LEDS they are cast in resin.

    So that'll be a total of 12 channels among the lights. The resistors are either 220 ohms or 150 ohms. I'm looking for ideas for control circuitry, I know I want to wire it to be in time to music but first I think I want to make some sort of buffer circuit that basically when there's a small input voltage it'll put a strong signal through to light the LEDs so I can hook it up to a wider variety of things.
    So just general ideas and suggestions would be neat as well as a schematic for the buffer circuit.
    I'm not opposed to doing arduino with this but am just curious on what you may suggest aside from that as well.

    Take a look at "color organ" circuits. See Bill's Blog. It's helpful for such stuff.
