    Default Arduino, what do I need?

    I have never done this microcontroller stuff. But damnit, I want to learn and I want to do it. Here is what I want to do:

    I want to have 2 led readout displays.

    1 that visually can show a number of resistance. This will read the resistance off of a sensor on my car (O2 sensor to be exact). So I can see rich/lean.

    1 that will visually display a number based off of another sensor that can read temps of up to 150F. Highly doubt i'll need to go that high but rather something like 80-100F.

    Is there any good tutorials where I can learn to do this and also, what will I need? I'm good with wiring and not at all intimidated by digging in and going head first into this kind of stuff. Just never done this kind of stuff before on the smaller scale.

    A good place to start is with something like this kit. As for interfacing with the car there's tons of people that have interfaced their Arduino's with an OBDII system (like this one or this one). And as for interfacing with a temp sensore there's TONS of resources online for reading a thermistor and displaying it on an LCD. You can pick up a 16x2 or bigger LCD screen and display everything on it.

    Take a look at my Maximum Security mod. I have the Arduino chip reading coolant temp and flow rate and displaying both on a 16x2 LCD with an RGB backlight. It also handles the door opening and closing functions.

    Second odbii link is dead....
    Two years. They were great. Let's make the next ones even better!

    OBDII wouldn't work, I'm megasquirt EFI standalone.

    However, the first link looks tasty. I think I could make something cool out of these:

    Would something like this be more than enough to display multiple functions?

    you'd be best off with this: http://www.adafruit.com/products/358 as it comes on a PCB which will make things a whole lot easier lol. I've never interfaced with one of those but those LCD's you can set up any way you want them as far as display goes.

    Oh, and for using the Arduino with Megasquirt check this out: http://www.ay60dxg.com/wordpress/loguino-data-logger/

    So much info... brain exploding... lol I'm seriously trying to sit down and read it and take it in piece by piece but there's so much info. Hard not to be slightly intimidated by it all.

    Waiting for my nice readout screen. But so far I'm getting the hang of this.
