LED SOUND PROJECT HELP

    Hi,
    I'm working on a painting that I want to incorporate some electronics
    into. I want to have a button on the front of the painting that, when
    pressed, will play a 20 second audio clip as well as cause two LEDs to
    flash for the duration of the sound. I see that you sell a sound
    circuit that looks like it will work for my sound needs. Is there a
    way to tie that in with an led circuit that will cause the lights to
    blink only for the duration of the sound clip? It's important that
    only one button triggers both the sound and the lights; and that it
    automatically shuts off after the sound clip is over. Also, the
    brighter the two lights, the better. I have some rudimentary
    experience with soldering and and electronics projects, but I do not
    have the skills to simply and efficiently execute what I have
    described here. Any advice, instructions, and/or diagrams you have
    would be helpful.
    Thank you,
    Mark

    Who is "you"? You were posting to a newsgroup. See this article to learn

    How do you want the LED to blink? Blining with the beat of the music, or
    just blinking? Which frequency and duty cycle?

    You could use one of those cheap MP3 players, attach a cheap PC active
    speaker to it and use the audio output of the MP3 player to control an LED
    (amplified with an op-amp). If one button click doesn't start the sound,
    you could translate it with a small microcontroller.
