/diy/ - Do It Yourself

Hi Guys, I'm wondering if someone can help me? I'm trying to find out how to link up these in a circuit. Basically I have a quartz clock mechanism that runs on a single 1.5v AA battery, 4 Micro LED's that are 3-3.3V DC, and a 9V battery all operated in one circuit by this small switch I cant find out if this single 9v battery would be enough or what capacitor I would need. I have been trying to understand simple electronic circuits and it seems there was something about voltage drop in relation to the LED's, and if each LED is 3v, plus the clock mechanism then 9v would not be enough? Thanks if you could advise me
