Hi,

Can I "play" the sound heard in the video using the tone() function? Or does the fact that I can only play one note at a time mean that I can't get that smooth rising transition? If tone() is not the way to go, any suggestions?  :~

Here is the code I am using:
Code: [Select]
*/
#include "pitches.h"

// notes in the melody:
int melody[] = {
  NOTE_C4, NOTE_C5};

// note durations: 4 = quarter note, 8 = eighth note, etc.:
int noteDurations[] = {
  1, 1 };

void setup() {
  // iterate over the notes of the melody:
  for (int thisNote = 0; thisNote < 3; thisNote++) {

    // to calculate the note duration, take one second
    // divided by the note type.
    //e.g. quarter note = 1000 / 4, eighth note = 1000/8, etc.
    int noteDuration = 2000/noteDurations[thisNote];
    tone(8, melody[thisNote],noteDuration);

    // to distinguish the notes, set a minimum time between them.
    // the note's duration + 30% seems to work well:
    int pauseBetweenNotes = noteDuration * 1.0;
    delay(pauseBetweenNotes);
    // stop the tone playing:
    noTone(8);
  }
}

void loop() {
  // no need to repeat the melody.
}

what that sound is, is a frequency generator with someone farting around with the knob, no notes or any other musical association

find a start and stop frequency and try a for loop
