So far, it sounds like you've done just about everything wrong.
Applying voltages that you haven't checked beforehand, using the
wrong batteries, applying reversed polarities at just about every
possible place, incorrect jumpering on the oopic boards, etc. Plus
providing rather poor descriptions of your problems. If you mean r/c
servo, say "servo" not "motor", etc.

First off, get yourself some fuses in the battery lines, use your
voltmeter to check voltages before hooking up, and double-check
everything before doing it.

Then, after you do anything, IMMEDIATELY probe around with your
finger for overheated components.

You need some better discipline when playing with electronics. Fixing
bugs in hardware is a lot more painful than in software.
