  • Found this: http://www.hazelwoodsound.com/motorized-faders-and-the-arduino/

    You can find more results by searching for “motorized fader,” as it seems the most popular application of this component is with audio mixers.

  • +1 for example wiring and code.

  • The motor_go function is a bit confusing, particularly the relationship between the step size and increment values. I keep getting an error in my Serial Window that reads “incorrect value for motor_go().” What is causing this? I don’t see anything in the forums on this question.

  • Found the problem. In the .cpp and .h file included in the library, you need to change

    #include "WProgram.h"

    to ->

    #include "Arduino.h"

    This is if you’re running 1.0.1. Not sure about other versions. This will also be true for any library written before this change in the Arduino software.

  • Udpate: solved one problem, have new one. The prior error was due to running the code and its libraries from inside a Dropbox folder. That’s a no-no. I moved everything into the Documents > Arduino > Libraries folder and compiled and get a new error: “ Error Compiling: In file included from quad_step_test.cpp:43: /Users/matthewepler/Documents/Arduino/libraries/quadstep/quadstep.h:12:22: error: WProgram.h: No such file or directory”

    Clues? -M

  • Is anyone else having trouble compiling the example in the library? I’m getting a definition/class error: ‘quadstep does not name a type.’ No changes were made to the Example and it’s in the right place. -M

No public wish lists :(
