Hello Tod! Thanks for all of the help. I am learning along side some design students, trying to integrate the arduino into some products. One student wants to create a piezo project that can play two melodies from two piezos wired into one arduino. Do you have any suggestions?

Hi mae, For the Arduino sketch, grab "piezo_read.pde" above and replace the "loop()" function with something that will look at each piezo and send out via serial the number of the piezo that's been hit. Something like this:

int numPiezos = 6;
void loop() { 
  digitalWrite(ledPin,LOW);     // indicate we're waiting
  for( int i=0; i= THRESHOLD ) {      // is it bigger than our minimum?
      digitalWrite(ledPin, HIGH); // tell the world
      t = 0;
      while(analogRead( i ) >= (THRESHOLD/2)) {
        t++;
      } // wait for it to go LOW  (with a little hysteresis)
      if(t!=0) 
        Serial.println( i );  // print out the number of the piezo read
    }
  }
}

Then in the Processing sketch, you want to read that piezo number sent by the Arduino. That means the "serialEvent()" method in the "arduino_spookysounds.pde" sketch would turn into something like:

void serialEvent(Serial p) {
  int num = port.read();
  println("num="+num);        // print out the value read
  if( num >= 0 && num < num_sounds ) {
    myChannel[num].play(1);   // play a sound
  }
}

hi,
I was trying arduino_spookysounds and it works fine. I want to use six piezos. Can you tell me how to modify the sketches on Arduino and Processing so that each piezo plays its own sound?
thanks, mae
