  @lumicon -- if you search this forum for "stepper"

  • https://forum.processing.org/two/search?Search=stepper

  ...there are recent discussions of projects with 2 / 4 / 6 motors.

  You will need either multiple ardunios or an arduino with more IO ports, like the Mega series. Check this post for example:

  i'm thinking of realizing a kinetic sculpture

  Can you provide more details about your project? How do you make a sculpture with arduinos and 2D noise?

  great, thank you! so i figured that the mega 2560 R3 has 15 PWM outputs, which i probably could use for that, or?

  my next question would be; how to bring the 10 rotateY values to the 10 motors;

  void draw() {
    count = 10;
    translate(width/2, height+20, -boxsize); 
    float boxH = (float)height/count; 
  
    pushMatrix();
      for (int i=0; i<count; i++) {
        translate(0, -boxH, 0);
  
        float angle = myNoise((float)i/20, (float)frameCount/100, 0) * TWO_PI; 
        pushMatrix();
          rotateY(angle); // these values via arduino...
          box(boxsize, -boxH, boxsize/10);
        popMatrix();
      }
    popMatrix();
  }
  

  ..will be quite simple, just 10 turning boxes, ...more later
