    Hello,

    After the giant LED gear indicator, I intend to build a big DIY cluster :)

    - Arduino
    - stepper motors : switec x27.168
    - lighted needles
    - GameDash

    61POa0iKjlL__SL500_AA300_.jpg switec x27.png $_57.JPG

    Here is a first trial video!



    It's really fine for a first test with a balsa needle, without optimization.

    To gain more speed, I'll supply the motors with 10V instead of arduino's 5V

    Why choose switec x27?
    - Because they draw really few amps: less than 20 mA so it can be driven directly from Arduino pins! :cool:
    - Because there are successfull DIY examples!

    Shopping List :

    • Switec X27.168
    these stepper motors are used in real cluster instrument

    a buyer guide

    the cheapest I found are on Aliexpress @2€ each
    http://www.aliexpress.com/item/5pcs...GMC-Cars-And-Trucks-2003-2006/1456148765.html

    but many can be found on eBay
    switec X27 search
    • some CMS LEDs to light the base of the transparent needle
    led spec.jpg led.jpg white 1206 smd led
    I got 50 leds for 1€60
    http://www.ebay.fr/itm/50-x-1206-White-Super-Bright-LED-SMD-SMT-Bulb-Lamp-Light-High-Brightness

    or 100x for 3$ on ebay.com

    LED Type : SMD 1206 LED
    Lens Colour : Water Clear
    Emitted Colour : White
    Peak Wave Length (nm) : 6000-7000K
    Forward Voltage (V) : 2.7 ~ 3.7
    Reverse Current (IR) VR=5V 50μA
    Viewing Angle : 130 Degree
    RoHS: YES
    Material:AlGaInP​
    Those leds are used in automotive cluster: so it will be perfect for my needs​
    • Arduino
    GameDash can only output to 1 USB ComPort. So I have to check how I'll drive my 4 or 5 motors with only one Arduino.
    - 1 Mega?
    - or 1 Uno with shifters or quad drivers?...
    • Downloading Arduino Library from Guy Carpenter
    https://github.com/clearwater/SwitecX25
    zip file

    This library is simple but elaborated as you can even tweak the acceleration depending of your needle inertia
    http://guy.carpenter.id.au/gaugette/2012/01/26/simplified-acceleration-model/
    • Power Supply
    Power supply concerns:
    - 12V is fine for LED supply and Arduino as well

    http://arduino.cc/en/Main/arduinoBoardUno
    - 1 Arduino 50 mA
    - 5 gauges lighting LED array will draw 5 x 10mA
    - 5 motors will draw 5 x 20mA

    This small PWU 12V 1A would be fine

    very good tutorial Cluster Tuning here
    http://www.dsmtuners.com/threads/how-to-light-gauge-cluster-with-leds.274519/

    Here a tutorial on How to drive LED (WS2801, WS2811 and WS2812) with Arduino
    http://www.tweaking4all.com/hardware/arduino/arduino-ws2812-led/

    Some nice resistor calculator online:
    http://led.linear1.org/led.wiz which deals with serial LEDs and write the results with a nice layout.
    -> R = 270 ohm

    and a good instructables about this subject
    http://www.instructables.com/id/Choosing-The-Resistor-To-Use-With-LEDs/?ALLSTEPS

    the LED are VERY small!
    I had to keep the previous LED under a wet tissu to prevent desoldering... when I soldered the next one... :mad:

    and it's fragile, i will need a round support:
    for the first one, I glued it! with bi-components glue

    Arduino code and GameDash settings:

    Here is a great arduino library dedicated to driving switec stepper motors
    http://guy.carpenter.id.au/gaugette/2012/02/16/using-the-switecx25-library/

    Here a first code which is functional with GameDash
    Code:
    /*
    Analogic Dashboard using Gamedash and Simtools
    and Switec X27.168 stepper motor
    and Arduino with Guy Carpenter's library "SwitecX25"
    by RacingMat 10-2014
    */
    
    #include "SwitecX25.h"
    
    // void stepUp();
    // void stepDown();
    // void zero();
    // void update();
    // void updateBlocking();
    // void setPosition(unsigned int pos);
    
    int TotalSteps = 315*3;  // for example 315 degrees of range = 315x3 steps = 945 steps
    byte Rpm;
    
    
      // declare MotorRPM with total steps and related pins (4-7)
      SwitecX25 MotorRPM(TotalSteps, 4,5,6,7); // the pins are set up to Output by the library
    void setup() {
       
      // run both motors against stops to re-zero
      MotorRPM.zero();  // this is a slow, blocking operation
      //MotorRPM.setPosition(427);
      Serial.begin(115200);
     }
    
    void loop() {
    // compiler l'arduino avec le tweak sur la longueur du buffer Serial pour comparer
    
    /*  // update motors frequently to allow them to step
      MotorRPM.update(); */
    
      // do stuff, call motorX.setPosition(step) to
      // direct needle to new position.
    if (Serial.available() > 0)  {
    //GameDash send RPM as values between 0 and 254
      Rpm = Serial.read();
      Serial.flush();
      }
     //call motorX.setPosition(step) to direct needle to new position.
     MotorRPM.setPosition(map(Rpm, 0, 255, 0, TotalSteps));
      // update motors frequently to allow them to step
      MotorRPM.update();
    
    }

    Switec wiring: the arduino drives the 2 poles with 4 digital pins.

    If I want to drive 5 gauges, I'll need to extend the number of digital pins...

    Nice concept built a couple of theses now and retro fitted a few dashboards with steppers.
    A little hint, you can try and use stepper lib to run them from code, I found very poor movements , very bad lag.
    Good luck,

    bad news...
    did you try this specific library? or Arduino stepper library?

    Yes I tried them all ages ago, actually had built one with the old software.

    The issue is if you have read the library's a little closer is that there call creates a blocking affect as in all code stops until that stepper has reached its desired location then the code moves on, when trying to drive more than one this causes the other to pause while it completes its move, with dials you need nice smooth control, the simplest and most effective way is with servos.
    Stepper motors require a tricky little bit of code to work correctly.

    Ok!
    I'll start by trying the Carpenter's library and share what I get at first trial with 5 gauges...
    :popcorna video to come... after I would have waited for their shipping :eek:

    If the code need some tuning, I'll share my concern and maybe need some help from you! :)

    I got 50 leds for 1€60 : cheap isn't it?
    http://www.ebay.fr/itm/50-x-1206-Wh...=AU_Car_Parts_Accessories&hash=item27e6a6ae1c

    or 100x for 3$ on ebay.com


    First time, I'll solder smd components!

    - 1 Arduino 50 mA
    - 5 gauges lighting LED array will draw 5 x 10mA
    - 5 motors will draw 5 x 20mA
    total = 2 Amp
