  what's the little piece of adhesive foam for?

  is it the "double-sided sticky tape" that you refer to for mounting the module to the board?

  ahh... you're getting this stuff from servo city?

  might you please explain, or sell separately, the "potentiometer/feedback" shaft as seen here and in your videos?

  thank you!

  as opposed to the example above, here's some code that will get this working right-away in true quadrature fashion. [model #E6A2-CW3C]

  sorry if it is wrong to post this here, but it's free to the world, have spark-fun!

  // code start
  
  [put pound sign here!]include "digitalWriteFast.h" // google this and install it
  
  const byte pin_A =  2; // connect white wire here
  const byte pin_B =  3; // connect black wire here
  int A_set =         0;
  int B_set =         0;
  long pulses =       0;
  
  
  void setup()
  {
    pinMode(pin_A, INPUT);
    digitalWrite(pin_A, HIGH); // enables pull-up resistor
    pinMode(pin_B, INPUT);
    digitalWrite(pin_B, HIGH); // enables pull-up resistor  
  
    A_set = digitalRead(pin_A);
    B_set = digitalRead(pin_B);
  
    attachInterrupt(0, encoderPinChange_A, CHANGE); // pin 2
    attachInterrupt(1, encoderPinChange_B, CHANGE); // pin 3
  
    Serial.begin(115200);  
  }
  
  
  void loop()
  {
    Serial.println(pulses);
  }
  
  
  void encoderPinChange_A()
  {
    A_set = digitalReadFast2(pin_A) == HIGH;
    pulses += (A_set != B_set) ? +1 : -1;
  }
  
  
  void encoderPinChange_B()
  {
    B_set = digitalReadFast2(pin_B) == HIGH;
    pulses += (A_set == B_set) ? +1 : -1;
  }

  I've had great success in narrowing the gap on these simply by gluing a piece of tubing on the LED side, the transistor side... or both.

No public wish lists :(
