Hi,

Ok I have a r/c submarine and i need some form of electronic sensor to
keep
it level. Onboard power is 7.2V.

mercury tilt switches are the traditional tool for detecting tilts.

but would it be possible to lower the centre of gravity enough that it
could be self-leveling?

The problem is that you have to alter the angle to dive.

I thought subs dived by emptying thier float tanks...

So if it was
self-levelling then it would never get under.

that's not a big problem just have fins at the bow or a movable weight
that can point the front up or down.

In a real sub, you first fill the ballast tanks and that gets them under,
then you use the 'fins' at the front and back to change depth. However some
of ours just use the planes to go under.

Thanks for the answers, however I have one question:
I have a play controller from many years ago now, that when you turn it, it
turned the car, character whatever on screen. There is a little window on
it, and through that window you could see a chip. Couldn't I use a chip like
that?
