Switching based on steering wheel voltage/resistance
Hi Chaps,
I'm looking for a simple solution to a problem I have. It's a typical tin-top set up where I have steering wheel with
horn/shift-up/shift-down buttons, all feeding through a single clock-spring cable via a resistance ladder, and from those variable resistances (or
voltages) I need to switch one of three relays.
I'd rather not have to try to home-roll a mini Atmel or microprocessor based solution, does anyone know of anything simple/analogue, or even off
the shelf, that can give me a head start?
Cheers
Gary

a friend of mine is running his indicators and horn via a bluetooth connection and no cables from the steering wheel....
runs on a 3v battery and goes to sleep after the button is pressed.....
I'd love to give my imaginary friend a great big hug,
but this jacket makes it impossible.

Are the resistors in the steering wheel so that the coiled cable has 2 wires (or even 1 wire if the steering wheel is earthed)
If that is the case lm3914 is a simple solution.
