Hi Ronv,
I did wash a cat once, but it was with a garden hose, so not
difficult.
Sorry that I am not good at explaining, I spend a lot of time
composing answers, to be as clear as possible. Im sure if I
explain the whole thing it will be far too complicated to
explain clearly, this is why I have kept it as brief as
possible, only concentrating on the weakest section, the
WIRE/COIL to A/D bit. Once I get good A/D signals, the rest
will work.
In #64 I said the WIRE is always stretched out, never coiled
up.
I think if I simply stick to getting the long WIRE working,
then I'm sure I will get the shorter WIREs to work.
I think I understand your
resistance/induction/voltage/current explanation. I'll do
some tests with what I've got, with adjustments based on your
answers.
I use quite large Golf Buggy batteries, so I'll do a time
test with them.
I am happy to think about a different way of doing things.
