    First off,

    you have to connect your switch to either the J3 or J4 connection interface.
    This is just a connection and will not provide power for your led.

    You will connect your led to the J2 interface. J2 has 5 volts of power supplied.

    To set up your led, you set it up like this;

    On J2, Pin #1 has 5 volts supplied all of the time, dont use this.
    Pin #2 is the ground that you will use for all of your LEDs.

    So, the first led would be connected as;


    Pin #3---------->Resistor------>LED---------Pin #2 (ground)

    a second led would be conected like

    Pin #4---------->Resistor------>LED---------Pin #2 (ground again)




    Use the I/O confiquration;


    Hope this helps.
