Volume and motion

Processing Electronics (Arduino, etc.)

I wrote a code where the amplitude of a audio input is mapped to the amplitude of a sin function. Right now is just controlling the position of ellipse on a screen but i want this motion to be applied to a drawing machine using an Arduino, possibly a servo motor.
does any one have an example of how to convert this to using a motor?

import processing.sound.*;
Amplitude amp;
AudioIn in;

float s;//s is a map of the analyzer
float c;
float p;
float e;//speed
float range;
float v; //vertical movement

void setup(){
  size(1000,1000);
   amp = new Amplitude(this);
   in = new AudioIn(this, 0);
   in.start();
  amp.input(in);
  colorMode(HSB,360,100,100);

  s=0;
  e=0;
  v=0;
   background(c,100,100);
   noStroke();

}

void draw(){
  range=map(amp.analyze(),0,1,500,1500);
  e=e+1;
  p=map(sin(e),0,1,500,range);
  //c=map(amp.analyze(),0,.5,0,360);
  ellipse(p,v,5,5);
 // s=map(amp.analyze(),0,1,100,800); 
  v=v+.1;
  
  
  
}

Welcome to the forums!

What exactly is your question?

Hi! thanks,
I am asking if someone knows or have an example on how to convert this to using a motor?

I’d suggest looking at specific servo setups – it is much better to decide what hardware you want to target, specifically, before trying to get it to do what you want.

Are you sure that what you want is arduino? As opposed to a PC-connected AxiDraw, etc.?
