  Speeduino - Arduino based engine management

Speeduino can be a great reference for anything auto-related! It's an open source ECU so does quite a lot of cool stuff, including reading tachometer values. From what I gather it uses a MAX9926 "VR Conditioner"; and the codebase may be a bit scary if you're new to this stuff.

A simpler - and common - approach would be using a hall effect sensor; there's some references here - github.com/rtbaker/ArduinoTachometer and StackOverflow.
