I need to make an old analog tachometer work with a diesel engine that does not originally have any tach on it.
I think the easiest is to get an stepper motor and driver and use signal from the alternator (like many aftermarket tachometers do).
The stepper will just directly drive the tachometer.
But I don't know how to convert and adjust the signal from the alternator so that the driver will understand it and output correct RPM to the stepper motor. Maybe something with Arduino? So I will need help with that or if you have any better ideas on how to do what I need. I have never done anything with Arduino but I have some experience with electronics, usually just following some guides. I do have soldering equipment and some basic components already.
