    Ok, so I working @ a museum and my requiremtns of the project is that The MP3 player uses flash memory to play 3 files one after another. To go along with this, When file1.mp3 is playing, the circuit is supposed to light up light1, when fil2.mp3 is playing , the circuit is supposed to light up light2, and the same idea for file3.mp3. What I have so far is:

    - An MP3 player
    - A 25 pin plug that connects to the MP3 player on one end, and there are two wires coming out of the plug, one is connected to a switch and the other wires goes into a relay (there it splits into 5 light gauge wires goin into the relay ports).
    - The relay it self with in and out ports
    - 120 V Tube lights (which is what i want to connect to the relay)

    MY QUESTION: Now there are 5 differents out ports from this relay, and I have no schematic as to which ports provides what signal. What I want to know is how do I connect the tube lights with my relay such that it meets the requirements (keep in mind the relay has alredy been configured to light up the correct light)

    Thank you. =)

    I would have no idea how this could be done. Here is a link to how a typical MP3 player works -

    There is no obvious way to get an indication about when one song has finished, and/or the next is being played.

    Maybe someone knows more than I do.
