ATtiny chip for simple conversions

Do you mean something like this?:



When I searched for ATtiny microchip, there showed several versions, small and bigger. For what I can see, you can solder it in any exp board and, yes, put it everywhere.

Two questions:

First: normally Arduino boards and these small chips use 5VDC or even less. How do we get that voltage from the 12 to 14 VDC of the car? I used a voltage divisor or such, with two resistors.

Second: how do we take the analog signals of the car (normally 0-12V) to input them in MPguino and ATmini without a) burn the microprocessor, b) alter the car parameters?

I am weak in electronic knowledge, just able to solder kits and circuits made by others and that is it.
