Any forum members with microprocessor experience?
Do any of you forum members have experience with programmable microprocessors such as Arduino, PIC, MBED, ARM. I am sure there are many others, but I am looking for a microprocessor to use for a little project in my '59. I would like to collect the signals from the ABS sensors and process them to show the amount of wheel spin of the rear tires relative to the front tires. This would require the accurate measurement of two 2Khz, 0-2.0V signals. Does anyone have a recommendation on which processor to use? I do have 'C' programming experience on DOS (remember DOS?) and Windows PC's so I would prefer to use 'C' as a programming language.

Charles, a lot of people don't like to venture there for some reason, but I've found a tremendous source of varied knowledge and experience in the OT section.
I've posted "wanted" type posts like this on a variety of subjects, including finding a graphic artist to work for public acknowledgement on a book, and been wildly successful.
Make a post there and see what happens.

Microchip (PIC) has a few MCU's that can handle what you are looking for. You need to decide how you are going to capture the pulses, by either counting for a set period of time or driving an interrupt.
You mention two sensors. I'm assuming one on the front and one on the rear. You might want to think about using four (especially if the car does not have a posi)
I have experience designing circuits for tachometers and fuel flow systems using pulsed inputs. Pretty easy, but you need to do some calculations to make sure the processor and clock freq you choose can capture the number of pulses you need, do you processing and output accurate data.
In the past I have used Freescale processors that have timer / capture ports that are designed for this type of pulsed input. I'm sure Microchip also has processors with timer / capture ports.
Have fun!!

PS: my experience is in the hardware development. I always had a GOOD software engineer working the code side

Charles,
Take a closer look at the Arduino offerings. You get a lot to like for little bitty dollars..... A/D inputs, D/A outputs (through PWM), digital I/O, and (if memory serves) floating point arithmetic.
Since you already know "C", you won't have any trouble adapting to Arduino programming. My forte' used to be hardware engineering (back when I was a productive member of society) and even I can figure out how to write code for the Arduino.

A couple of hardware guys have already chimed in.
I'm a software guy and am doing ARM development (c and c++) and work with guys who've worked with the Arduino.
From a software standpoint either of these 2 will allow you to write code in C. Your decision should probably be based on hardware requirements and cost.
