I'm trying to make my own custom automotive gauges. New gauges use stepper motors, but the requirements are quite a bit different than what you have for CNC. First, I think the speed would be considered extremely low. The tachometer and boost gauges would probably be the fastest responding, but gauges like coolant temperature and oil pressure hardly move at all.
I have a pic book and it explains how to accept an input and how to provide an output, but nothing about linking the two. The sensor information varies with the purpose. Some inputs are already a digital pulse train that vary the frequency, and others are simple 0 to 5V outputs that vary linearly with a change in the parameter. So I'm presented with two main challenges. The first is getting the inputs IN, and the second is getting the outputs OUT to the stepper motor.
So the question is: Could this be done with this circuit as is or like you mentioned to someone else, would I need a separate input circuit to combine with this as an output circuit?
Or better still, could I use one microcontroller that has enough capability to handle multiple gauges with all of these varying inputs and just hook up all the stepper motors to essentially one brain? What microcontroller would you suggest?
Sorry, if this question is too vague or too newb, but any direction would be helpful.
Another note is, of course, other than setting it up, no computer would be attached. I'm thinking there would be hookup and I could program some kind of cool start up and shut down sequence and I might want some kind of calibration ability in case the gauges needed adjustment, but after the computer is disconnected, the thing would just run on its own, like normal gauges.
Thank you.

Hello Dear Friends,
I have a final year project. My project has to control temperature (with heater and fan) and also this project has to turn stepper motor(example:4step left,4step right) periodly.
It means I have to control and steper motor in one PIC.
I have found some temperature control schematics and sources, also unipolar stepper motor control schematic and sources,, butt I can not merge them in the one PIC.
Please help me? If you want to see schematics, I can send documents to you immediately.
Have a good day,
kartal93th@yahoo.com
