It's the output pin (9) of the 556, which I believed generated
the pulse width (on that side of my board I have three pots
for centering the servo, and on the other side of the timer I
have the servo connection), but it doesn't make sense to me
that the servo is only getting that small of a voltage signal
to drive it. The side of the timer that has the servo connected
to it (I believe) generates the refresh (48Hz), but according to
my schematic attached in my first post (which lists two 555s),
that would make it backwards on my circuit board. I do get
the refresh signal on that side of the timer though. Soo, I'm
guessing it really is the PW generator side of the circuit that
is putting out that mv signal. Either way, when I make the
magnet stay still in the coil, that V signal stays extremely
constant, fluctuating up to 0.1mv, which in a scale of 1.0mv,
would be acceptable. So, I would bet the signal (where it is
I'm getting it at), is VERY stable. The other output pin (where
I get the oscillating signal), has a much higher V output, also.
But again, the signal I'm getting, from whatever part of the
circuit it is, changes with servo motion, remains stable, and
does not adversely affect the servo's operation when a draw
from my meter is applied.
