interface

Interface and Application Programming

In this assignment we have to develop an interface that responds to an input device or to be linked to an output device .

In this ocation, I used the Fabduino I built for the OUTPUT DEVICE assigment to send information to the computer through a serial port.

Then burn a program that filters the signal to piezoelectric and map it to translate it into visual information , I used processing for that , processing allowed me to generate a relationship between generative geometry and sound.

ARDUINO

int datoRead, datoWrite=0;

void setup() {

Serial.begin(9600);

pinMode(7, OUTPUT);

}

void loop() {

datoRead = analogRead(A0);//declara el pin de entrada

datoWrite= map(datoRead, 0,10,0,255); //mapeodel rango de la señal con el rango de tonos

Serial.write(datoWrite);//monitoreo de datos de entrada

if (datoRead>10){//condición

tone(7,datoWrite);}//entonces emite tono

if (datoRead>10){//condición

delay(1000);//entonces el tono dura este tiempo

}

noTone(7);//si la señal es menor a 10 no hay tono

}

PROCESSING

import processing.serial.*;

int val = 0; // To store data from serial port, used to color background

Serial port; // The serial port object

float a;

float b;

float h, x, y;

void setup() {

size(1330, 700);

port = new Serial(this, Serial.list()[0], 9600);

a = width/2;

b = height/2;

background(0);

}

void draw() {

println(val);

x = val;

y = 0.0049*x*x + x*0.001 + 5 ;

stroke(255);

line(a, b, x+width/2, y); // arriba derecha

line(a, b, width/2-x, y); //arriba izquierda

line(a, b, x+width/2, height-y);//abajo derecha

line(a, b, width/2-x, height-y); // abajo izquierda

line(x+width/2, y, width/2-x, y); // arriba

line(x+width/2, height-y, width/2-x, height-y); // abajo

line(x+width/2, b, width/2-x, b); // centro

line(x+width/2, b, a, y );

line(width/2-x, b, a, y ); //mirror arriba

line(x+width/2, b, a, height-y );

line(width/2-x, b, a, height-y ); //mirror abajo

}

void serialEvent(Serial port) {

// Data from the Serial port is read in serialEvent() using the read() function and assigned to the global variable: val

val = port.read();

// For debugging

// println( "Raw Input:" + val);
