ok after allot of search, i have decided that i will go with arduino , to read my car speed/rpm etc... the problem is, that my dashboard is completely ruined, so my only way would be to read the signals from the car sensors directly. i know that most of them wilgive 0-12v signal, and arduino reads only up to 5, but that can be solved. could anyone point me to a direction, at what signals do the sensors produce?? (i'm driving an audi 80 , b4 1990 , and i am corently interested, only in rpm,speed,temp,fuel sensors!!)
No announcement yet.
