    DFRobot Speaker v1.0 SKU: FIT0449   Contents     1 Introduction 2 Specifications 3 Pin Definitions 4 Connection Diagram 4.1 Sample Code 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)      Connection Diagram Speaker speaker with amplifier module connection diagram Note: The speaker signal input can be connected to any digital pin Sample Code /*************************************************** Super Mario Music ***************************************************/ #define NOTE_B0 31 #define NOTE_C1 33 #define NOTE_CS1 35 #define NOTE_D1 37 #define NOTE_DS1 39 #define NOTE_E1 41 #define NOTE_F1 44 #define NOTE_FS1 46 #define NOTE_G1 49 #define NOTE_GS1 52 #define NOTE_A1 55 #define NOTE_AS1 58 #define NOTE_B1 62 #define NOTE_C2 65 #define NOTE_CS2 69 #define NOTE_D2 73 #define NOTE_DS2 78 #define NOTE_E2 82 #define NOTE_F2 87 #define NOTE_FS2 93 #define NOTE_G2 98 #define NOTE_GS2 104 #define NOTE_A2 110 #define NOTE_AS2 117 #define NOTE_B2 123 #define NOTE_C3 131 #define NOTE_CS3 139 #define NOTE_D3 147 #define NOTE_DS3 156 #define NOTE_E3 165 #define NOTE_F3 175 #define NOTE_FS3 185 #define NOTE_G3 196 #define NOTE_GS3 208 #define NOTE_A3 220 #define NOTE_AS3 233 #define NOTE_B3 247 #define NOTE_C4 262 #define NOTE_CS4 277 #define NOTE_D4 294 #define NOTE_DS4 311 #define NOTE_E4 330 #define NOTE_F4 349 #define NOTE_FS4 370 #define NOTE_G4 392 #define NOTE_GS4 415 #define NOTE_A4 440 #define NOTE_AS4 466 #define NOTE_B4 494 #define NOTE_C5 523 #define NOTE_CS5 554 #define NOTE_D5 587 #define NOTE_DS5 622 #define NOTE_E5 659 #define NOTE_F5 698 #define NOTE_FS5 740 #define NOTE_G5 784 #define NOTE_GS5 831 #define NOTE_A5 880 #define NOTE_AS5 932 #define NOTE_B5 988 #define NOTE_C6 1047 #define NOTE_CS6 1109 #define NOTE_D6 1175 #define NOTE_DS6 1245 #define NOTE_E6 1319 #define NOTE_F6 1397 #define NOTE_FS6 1480 #define NOTE_G6 1568 #define NOTE_GS6 1661 #define NOTE_A6 1760 #define NOTE_AS6 1865 #define NOTE_B6 1976 #define NOTE_C7 2093 #define NOTE_CS7 2217 #define NOTE_D7 2349 #define NOTE_DS7 2489 #define NOTE_E7 2637 #define NOTE_F7 2794 #define NOTE_FS7 2960 #define NOTE_G7 3136 #define NOTE_GS7 3322 #define NOTE_A7 3520 #define NOTE_AS7 3729 #define NOTE_B7 3951 #define NOTE_C8 4186 #define NOTE_CS8 4435 #define NOTE_D8 4699 #define NOTE_DS8 4978 // notes in the melody: int melody[] = { NOTE_E4, NOTE_E4, NOTE_E4, NOTE_C4, NOTE_E4, NOTE_G4, NOTE_G3, NOTE_C4, NOTE_G3, NOTE_E3, NOTE_A3, NOTE_B3, NOTE_AS3, NOTE_A3, NOTE_G3, NOTE _E4, NOTE_G4, NOTE_A4, NOTE_F4, NOTE_G4, NOTE_E4, NOTE_C4, NOTE_D4, NOTE_B3, NOTE_C4, NOTE_G3, NOTE_E3, NOTE_A3, NOTE_B3, NOTE_AS3, NOTE_A3, NOTE_G3, NOTE _E4, NOTE_G4, NOTE_A4, NOTE_F4, NOTE_G4, NOTE_E4, NOTE_C4, NOTE_D4, NOTE_B3, NOTE_G4, NOTE_FS4, NOTE_E4, NOTE_DS4, NOTE_E4, NOTE_GS3, NOTE_A3, NOTE_C4, NO TE_A3, NOTE_C4, NOTE_D4, NOTE_G4, NOTE_FS4, NOTE_E4, NOTE_DS4, NOTE_E4, NOTE_ C5, NOTE_C5, NOTE_C5, NOTE_G4, NOTE_FS4, NOTE_E4, NOTE_DS4, NOTE_E4, NOTE_GS3, NOTE_A3, NOTE_C4, NO TE_A3, NOTE_C4, NOTE_D4, NOTE_DS4, NOTE_D4, NOTE_C4, NOTE_C4, NOTE_C4, NOTE_C4, NOTE_C4, NOTE_D4, NOTE_E4, NOTE_C4, NOTE_A3, NOTE_ G3, NOTE_C4, NOTE_C4, NOTE_C4, NOTE_C4, NOTE_D4, NOTE_E4, NOTE_C4, NOTE_C4, NOTE_C4, NOTE_C4, NOTE_D4, NOTE_E4, NOTE_C4, NOTE_A3, NOTE_ G3 }; // note durations: 4 = quarter note, 8 = eighth note, etc.: int noteDurations[] = { 8,4,4,8,4,2,2, 3,3,3,4,4,8,4,8,8,8,4,8,4,3,8,8,3, 3,3,3,4,4,8,4,8,8,8,4,8,4,3,8,8,2, 8,8,8,4,4,8,8,4,8,8,3,8,8,8,4,4,4,8,2, 8,8,8,4,4,8,8,4,8,8,3,3,3,1, 8,4,4,8,4,8,4,8,2,8,4,4,8,4,1, 8,4,4,8,4,8,4,8,2 }; void setup() { // 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.
