Playing Despacito on an Arduino

by

Playing Despacito or any other music/beat on Arduino. Sounds impossible but it actually possible

 

How? ……………… Lets Discuss along with code and a diagram for making your project more easy.

Equipment’s or Things we need for making this Project:

  1. Buzzer

 

 

 

2.Arduino

 

Code:

#define SPEAKER 3
#define DRUMS 5
#define INTERVAL 160
#define NOTE_SPACING 16
const uint16_t FREQUENCIES[]={0,31,33,35,37,39,41,44,46,49,52,55,58,62,65,69,73,78,82,87,93,98,104,110,117,123,131,139,147,156,165,175,185,196,208,220,233,247,262,277,294,311,330,349,370,392,415,440,466,494,523,554,587,622,659,698,740,784,831,880,932,988,1047,1109,1175,1245,1319,1397,1480,1568,1661,1760,1865,1976,2093,2217,2349,2489,2637,2794,2960,3136,3322,3520,3729,3951,4186,4435,4699,4978};

void setup() {
pinMode(SPEAKER,OUTPUT);
pinMode(DRUMS,OUTPUT);
}
uint16_t ctr=0,t=0;
void loop() {
t=millis();
if(LEADLN[ctr]!=0){
noTone(SPEAKER);
if(LEADTK[ctr]!=0) tone(SPEAKER,FREQUENCIES[LEADTK[ctr]],LEADLN[ctr]*INTERVAL-NOTE_SPACING);
}
if(DRUMTK[ctr]!=0){
digitalWrite(DRUMS,HIGH);
delay(DRUMTK[ctr]);
digitalWrite(DRUMS,LOW);
}
ctr=(ctr+1)%SONG_LENGTH;
delay(INTERVAL-(millis()-t));
}
