Let me start by stating that I have never worked with an Arduino but it looks like something I would have fun with, so I am asking for a kit for Christmas from my wife.
Here is the setup.
I took the factory radio out of my car and put in an aftermarket unit. The problem is that the trip computer is controlled by buttons that are built into the radio. I am quite capable of setting up the radio on a bench and viewing what the signal looks like when I press the different buttons.
The project I am considering is to mimic this using something like an Arduino that I can connect momentary switches (buttons) to that can then output the required signals.
Can the Arduino do this once I get the hang of programming it or is there a better option?
Is the Arduino a good choice for this project?

Re: Is the Arduino a good choice for this project?
It really depends on what you find the signal to be - it doesn't sound like you've done the experiment yet. The atmega chip in an arduino can generate a variety of serial data formats, either using it's built in peripheral or by "big-banging" them in software (people even do USB's lowest speed in software) but there are also many things it can't do without support circuitry, often in the form of a "shield". Though most of the arduino + shield combinations price out to be more expense and less capable than some other micro-controller with that peripheral built in.
But until you know what you need, it's a guessing game.
The arduino isn't a bad board to have around regardless, either using the arduino software or just treating it as an avr chip with bootloader on a convenient board.

The aruino looks like fun for someone who likes to tinker, so I want one anyway. I guess I'll ask for one of those kits to allow you to use your laptop as an o-scope as well. I really don't want to set up at work to do my testing as that is not my department. They won't mind, but still...
I'll come back after christmas when I have more information on the signal.
Thanks for the help.
