Oh sorry I meant because I'm not using the paddleshift stuff just egear I'm using audi trans. I just made mine with 3 buttons.

Thanks Dustin!  ::angel
are there parts to the breadboard wiring I don't need?
Do not needbread board,  solder all connections ,  you ca buy  break away pins at pololu  to connect at  arduino

Here is a resource link explaining the use of the 10K ohm resistors and why the are needed.

You will not need to last 2 buttons, they are for the paddles and you are using the triptronic function. Everything else you will need.


You don't need the little LED I just put that there to verify power...

Here is what everyone is waiting for this is the wiring diagram::thumbup


Some stuff is kind of confusing the top right picture is your car battery or 12 volt power supply. The motor simulates the Actuator with feedback (the diagram I used didn't have a actuator). Make sure your communication (tx & rx) between the two are reversed so there is communication between the Arduino and the JRK.

Batwings and temp is easy, just hook your actuator to your fan relay so when your fans come on your wings rise. The only 1/2 tricky part is at around 80 the wings need to come down so they don't get ripped off from the wind speed  ::beers

I am working on a factory style odometer with trip meter,
 I am using a basic  black on green lcd ,  trying to find one green on black like factory but programming should be same...  from looks of it  , it might not be to bad at all to make the wings function based on speed, not looked to much into temp but probably would not be  hard either.  which would be preferred  bat wings based on speed or temp?

Getting the speed in there is as simple as adding a GPS module and writing the code to look at the speed and trigger actuator position based on the GPS data.

Example:

1. 0 - 5mph @ 3 seconds = Home (down) position
2. 6 - 30mph = position 1 (1/4 way)
3. 31 - 60mph = position 2 (1/2 way)
4. 61 - 200mph = position full up (no 3/4 position because someone behind you wouldn't notice it)

GPS modules typically put out a series of standard strings of information, under something called the National Marine Electronics Association (NMEA) protocol. More information on NMEA standard data strings can be found at this site

The tutorial code at the bottom of this page demonstrates how to decode and display the most common string, called $GPRMC. If all you need is date, time and position, you can to skip reading this, and just run the code below.

While you can write software to serially request other strings from the Parallax module, the following strings are automatically transmitted when the "/RAW" pin is pulled low.

    $GPGGA: Global Positioning System Fix Data
    $GPGSV: GPS satellites in view
    $GPGSA: GPS DOP and active satellites
    $GPRMC: Recommended minimum specific GPS/Transit data

Each of these sentences contains a wealth of data. For example, here are a few instances of the $GPRMC string, aka the "Recommended minimum specific GPS/Transit data" string:

 eg1. $GPRMC,081836,A,3751.65,S,14507.36,E,000.0,360.0,130998,011.3,E*62
 eg2. $GPRMC,225446,A,4916.45,N,12311.12,W,000.5,054.7,191194,020.3,E*68

           225446       Time of fix 22:54:46 UTC
           A            Navigation receiver warning A = Valid position, V = Warning
           4916.45,N    Latitude 49 deg. 16.45 min. North
           12311.12,W   Longitude 123 deg. 11.12 min. West
           000.5        Speed over ground, Knots
           054.7        Course Made Good, degrees true
           191194       UTC Date of fix, 19 November 1994
           020.3,E      Magnetic variation, 20.3 deg. East
           *68          mandatory checksum

 eg3. $GPRMC,220516,A,5133.82,N,00042.24,W,173.8,231.8,130694,004.2,W*70
              1    2    3    4    5     6    7    8      9     10  11 12

      1   220516     Time Stamp
      2   A          validity - A-ok, V-invalid
      3   5133.82    current Latitude
      4   N          North/South
      5   00042.24   current Longitude
      6   W          East/West
      7   173.8      Speed in knots
      8   231.8      True course
      9   130694     Date Stamp
      10  004.2      Variation

Great work! Any chance of a wiring diagram to show how the 2 computer and the motor controller are connected together and the switches are tied into the system.
Thanks for sharing your work.

The "VIN" and "GND" on the JRK actuator control unit will be a 12 volt power supply from your battery. If the actuator wont move that may be the problem.
