  • 'Simple' Data Processing/LCD Readout

    Hi there,

    Ive been hunting round the internet for a few days for a simple solution to how I could solve what I want to do...

    I know bits and bobs about electronics, but mainly all I do is join wires and the simple stuff

    My problem is... I have produced a full loom for a car, well, its pretty small as its just the bare essentials, although I kept a few things in that I was hoping to use, them being: Operating Oil Pressure + Operating Oil Temprature.

    Now, these two are single wires, from sensors on the engine block. Ive had a play around with the multi meter, and got some readings of the oil pressure while the engine is in operation... I used the multi meter in 'Ω 200' mode, and the readings showed up like:

    5 Bar = -196.0~
    4 Bar = -178.0~
    3 Bar = -160.0~
    2 Bar = -143.0~

    All approx values, I wont bother with the oil temprature yet as its pretty much the same readings, and Im just trying to work out how easy this is going to be to do...

    What im trying to do is display the current operating oil pressure and temprature on a small LCD display (2x16) that is going to go in a blank space on the clockset. Im just wondering what I need to get this working...

    Some sort of LCD controller? Obviously something will need to be programmed? (I have done programming before), So im just wondering if anyone has any ideas of what needs doing for me to be able to display the two pieces of data on a small LCD!

    I dont really know much about controllers etc, but I want to learn and get this sorted, as Ive wanted it from day 1!

    Thanks if anyone can give any ideas!

    You could use a microcontroller (PIC or AVR) and connect it to a Character LCD screen, then read the resistance and display the value on the Character LCD. All in all you should be able to do this for under $50 in parts (+ $30-$60 in the tools required to program/debug/assemble the circuit) I can find you some links if you want

      I've Been thinking of doing the same thing ! Would really appreciate if someone posts an easy to use beginners guide to this ! Thanks !

        I think you can use an Arduino board to do this. You can program the board using your PC and then use it to drive the LCD display.
