Introduction

This speaker module is based on the 8002 speaker amplifier IC. It can be used as a buzzer and also

to play high quality audio. Volume output is controlled via the potentiometer.

The module has a compact footprint, simple interface, wide voltage input range, long service life and

various other advantages. It can be used with an Arduino I/O expansion shield for interactive, sound

related creations.

Specifications

 Operating voltage: 2.0 - 5.5V

 Interface Type: Digital

 Module size: 40mm x 40mm/ 1.57 inches x 1.57 inches

 Support Gravity interface

 Power rating (Speaker component): 0.5W

 Impedance (Speaker component): 8 ohm

PinDefinitions

1. Ground (GND)

2. Power supply (VCC)

3. Input signal (Signal)

// iterate over the notes of the melody:

for (int thisNote = 0; thisNote < 98; 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 = 800/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 * 1.30;

delay(pauseBetweenNotes);

// stop the tone playing:

noTone(8);

}

void loop() {

// no need to repeat the melody.

}

If you want to melody to play repeatedly, move the setup part of the code to the main loop of the

program.
