Code: [Select]
void setup()
{
  pinMode(2, OUTPUT);
}

void loop()
{
  tone (3,1000,100);
  digitalWrite(2, HIGH);
  delay (500);
  digitalWrite(2, LOW);
  delay (500);
}

Probably the piezo is reflecting the sound into the breadboard which then becomes a sound board.
Note, you are calling this a piezo buzzer, is this a buzzer or a piezo speaker?
