    You can use relay board to control this thing right?

    Ok i got something else (cheaper )

    http://www.vandijkenelektronica.nl/s...ages&index=548

    Its a stepper motor, 9v but works perfect on 12v, uses a 1$ ULN2003 and it can connect 3 motors to 1 paralelport. Gives lotsa force and only 7 degress per step, very accurate

    Might install them in my own car too..

    Please forgive the noob question... but does anyone have a picture of servos hooked up to there HVAC or does anyone have any pictures at all of a relay settup for controlling their cars controls??

    Thanks in advance

    I tried to interface my LCD too.. I think it can be done but it is a pain in the a**.. So I will just fabricate the LCD!!

    You can turn down the voltage from phidget by decreasing the speed!!!
    The speed is controlled by voltage..
    But in the software you shouldn't overide 9V!!!

    About the sliders and servos...
    Think what they use on R/C's...
    i.e. to turn the wheels!!!
    So, yes you can do it...

    You can use a pararell port to controll 8 relays.
    I got a PCB and the component list that is needed to this...
    Also easy software to controll 8 ports (high/low)

    Maby it could be a next future in frudoplayer?

    My project has been on the back burner for quite some time. I unfortunately lost a hard drive with it all of my source code. I haven't had the desire to continue with it at this point because of that. I also have soooo many other things going on I haven't had the time. I will get to it eventually.

    I am able to control 6 relays(all I needed) via a microcontroller through the serial port. I liked serial because of the usb->serial connectivity if I needed an extra for something else. Serial real estate isn't cheap

    I personally prefer this method to any of the off the shelf products as it is catered to my needs not "the masses". To help anyone along attached is the schematic I used. Never corrected schematic it's a 220 Ohm resistor, not 680.

    would it be posible to connect a thermometer and have the computer calculate everything necissary to keep the car at that temp...
    So if you have set to 70* F and its 80* F the comp would turn the air up until it reaches desiderd temp.

    Would this be possible?
