  There is a Metal Nut underneath.

  Yes, they will indeed.

  I just received this interesting little doodad, I'm using it with a Teensy 3.0 and here is some demo Code I wrote for it. Maybe it can help some others out. I haven't had the issue with it that others have been seeing described as poor build quality. Also, the comment from Member #333036 was pretty spot on as far as pin out. I used the encoder library from PJRC found here example which handles this device well. It does however increment +-4 every tick of the detent so just be careful when coding.

  #include 
  
  Encoder encoder(A5, A4); //These 2 pins are A and B of the encoder side, C is connected to ground
  
  const int redPin =  10; 
  const int greenPin =  A8;
  const int bluePin =  9;
  volatile boolean encoder_button = false;
  
  void setup() {
    Serial.begin(9600);
    pinMode(A3, INPUT);
    pinMode(redPin, OUTPUT);
    pinMode(greenPin, OUTPUT);
    pinMode(bluePin, OUTPUT);
    attachInterrupt(A3, buttonPush, CHANGE);
  }
  
  void loop() {
    int32_t value;
    value = encoder.read();
      Serial.print("value = ");
      Serial.println(value);
  
    if (Serial.available()) {
      Serial.read();
      Serial.println("Reset Encoder to Zero");
      encoder.write(0);
    }
    if(encoder_button)
    {
      for(int i=0; i< 20; i++) //Careful with this if you or a friend has epilepsy 
      {
        setColor(255, 255, 255);
        delay(10);
        setColor(0, 0, 0);
        delay(100);
      }
      encoder_button = false;
      Serial.println("Button Pushed");
    }
    else
    {
      setColor(value,0,0);
      delay(1000);  
      setColor(0,value,0);
      delay(1000);
      setColor(0,0,value);
      delay(1000);
    }
  }
  
  void buttonPush()
  {
    encoder_button = true;
  }
  
  void setColor(int red, int green, int blue)
  {
    analogWrite(redPin, red);
    analogWrite(greenPin, green);
    analogWrite(bluePin, blue);  
  }

  It's mostly the read function from what I debugged, I ended up with this and it works as far as I can tell on my 1999 Explorer.

  //Define Serial Ports so I remember which is which
  #define PC Serial
  #define OBD Serial2
  
  //Set up ring buffer
  char rxData[20];
  char rxIndex=0;
  
  void setup() 
  {
     PC.begin(9600);
     OBD.begin(9600);
  
     ODB_init();
  }
  
  void loop() 
  {
    PC.println(getRPM()); //Print the int returned from getRPM
    delay(2000);//wait 2 seconds and grab another reading
  }
  
  void ODB_init(void)
  {
    //Wait for a little while before sending the reset command to the OBD-II-UART
    delay(2000);
    //Reset the OBD-II-UART
    OBD.print("ATZ\r");
    //Wait for a bit before starting to send commands after the reset.
    delay(2000);
    OBD_read();
    OBD.print("ATE0\r");
    OBD_read();
    OBD.flush();  
  }
  
  int getRPM(void)
  {
    //Query the OBD-II-UART for the Vehicle rpm
    OBD.flush();
    OBD.print("010C\r");
    OBD_read();
    return ((strtol(&rxData[6],0,16)*256)+strtol(&rxData[9],0,16))/4;
  }
  
  void OBD_read(void)
  {
    char c;
    do{
      if(OBD.available() > 0)
      {
        c = OBD.read();
        PC.print(c);
        if((c!= '>') && (c!='\r') && (c!='\n')) //Keep these out of our buffer
        {
          rxData[rxIndex++] = c; //Add whatever we receive to the buffer
        }  
       }     
    }while(c != '>'); //The ELM327 ends its response with this char so when we get it we exit out.
    rxData[rxIndex++] = '\0';//Converts the array into a string
    rxIndex=0; //Set this to 0 so next time we call the read we get a "clean buffer"
  }
  

  Sorry if that code is formatted super funky, First post with code in it ^_^

  Cheers hope that helps out somebody.

  --Why was he retired? --He got old. Then some thumb-sucker came along and tagged him "RED". --Red? --Yeah, RED. R-E-D, "Retired, Extremely Dangerous".

  I thought this fit though it is a movie quote.

No public wish lists :(
