I made a little box for my son which has a bunch of different types of 
switches and some LED's.  It's also got a pot and a little buzzer so he 
can turn the volume up and down.  He really likes it but after a day the 
battery dies.  I've got a 9 volt hooked up to everything.  I have 
battery hooked directly up to the switches and then the switches are 
connected to the led's with a resistor in between. 

So am I missing some key part that would help from draining the 
battery?  LED's shouldn't drain a 9 volt battery that quickly and the 
buzzer is almost never on.  Really, only 1 or 2 led's are lit at any 
given time and they're really low volt led's.

Thanks for any help,
Shay
