hi,
i am developing a project in which we are taking the output of fuel guage of a car.the output of fuel guage will be in the range of 0-12v,i want it to convert to 0-5v range so that i can connect it to an adc and take the digital value from it.so how do i convert the voltage level...??
 
If your 0..12V input signal is linear, a simple voltage divider circuit can be used.

One 2k2 resistor and one 2k pot, set for about 1.57k will do.

(Google “voltage divider calculator” for more info)
 
Car fuel gauges usually use a pulsed signal from a bimetallic voltage regulator whose average output voltage is 5v.
