This is the greatest.

Got it.  People who call Tone::begin repeatedly in the loop need their head examined.

Oh, and I did think that the Tone object was getting destroyed so I put it as a global and it made no difference.

Ok - I simplified this and the issue is the tone library

I still get three beeps for the following

Code:

void loop() {

  // Read the accelerometer
//  readAccel();
  Tone tone1;
  tone1.begin(rightBuzzerPin);
  tone1.play(NOTE_A4,550);
  
 // tone2.begin(leftBuzzerPin);
 // tone2.play(NOTE_A4);
 
  delay(600);

}

The x,y,z reappear in the loop.

I tried powering off an external battery.  Very good idea that - you never really know if you're sending enough current.  However, vene then we get three beeps and it stops.  Same as before.

This makes no real sense to me.

Ok - will do.

The sprintf's are a good buffer over-run candidate but would they affect timing here or something?

Guys,

I have a lilypad with the standard accelerometer and a buzzer.  I can read the accel just fine but if I use the tone library as well I can read the accel three times, make three tones, and then it all just hangs.  Is this some wierd interrupt thing?

Code follows .. thx in advance.

#include <bassdll.h>
#include <debug.h>

#include <stdlib.h> // for malloc and free
void* operator new(size_t size) { return malloc(size); }

  }

  pinMode(leftBuzzerPin, OUTPUT);
  pinMode(rightBuzzerPin, OUTPUT);
  pinMode(vibratorPin, OUTPUT);

  pinMode(xPin, INPUT);
  pinMode(yPin, INPUT);
  pinMode(zPin, INPUT);
}

// Read the accelerometer.
void readAccel(int &x, int &y, int &z) {

  x = analogRead(xPin);
  y = analogRead(yPin);
  z = analogRead(zPin);

  
}

Tone tone1;
Tone tone2;

void loop() {

  int x = 0, y = 0, z = 0;
  // Read the accelerometer
  readAccel(x,y,z);

  char buffer[56];
  sprintf(buffer, "(x,y,z) = (%d,%d,%d)", x, y, z);
  
  Serial.println(buffer);
  
  sprintf(buffer, "(x,y,z) = (%d)", NOTE_A4  + x / 100);
  
  Serial.println(buffer);

  tone1.begin(rightBuzzerPin);
  tone1.play(NOTE_A4,100 );
  
//  tone2.begin(leftBuzzerPin);
//  tone2.play(NOTE_A4);
 
  delay(800);

}

What do folks use to connect pins (like ribbon cable pins) to wires?  I'm looking for individual pin connectors not just ribbon cable terminators.  Part #s would be great if you have them.  

I'm writing a blog about my three year old's adventures in arduino.  My current pet project is a thomas table that has sensors for trains passing that activate mp3 sounds.  It also plays his favourite tunes when buttons are pressed. There are full code samples and descriptions of how to wire it all up.  I hope y'all enjoy it.
