Hi, I am working on a PCB design and the mock-up prototype is now done, thanks for all your help by the way!
now its time to get it mobile. I am trying to add a battery (CR2032) to the design of the PCB,
the thing is that I have my voltage regulator set up as so:

but I don't know how to hook up the batteries,
the voltage regulator is supposed to take a voltage in of 7.2V (from 2 CR2032 rechargeable batteries at 3.6V each)
and one stream is supposed to feed a RF transmitter at 3.3V (the bottom regulator)
the top one is a 7805 that outputs 5V to drive the other circuit.I was confused as the battery symbol (that comes in adafruit library) has 3 leads, from what I remember soldering, 2 of them are positive? and 1 is negative, but should I link the negative to the ground? or how should I wire it up
thank you!
