Hello again,
So, my project is basically adding onto the Arduino "Pitchs.h" library. My problem is that the Arduino will freeze after its done playing the sound. I have a piezo hooked up to pin 8 and a button and an LCD for testing the loop. Here are my codes:
//Sketch
#include <AdvancedSound.h>
AdvancedSound aSound(8);
#include <LiquidCrystal.h> //Import LiquidCrystal library for LCD functionality.
LiquidCrystal lcd(13, 7, 4, 2, 1, 0); //Define LCD pin layout.
int introMelody[] = { //Melody to be played on startup.
NOTE_G5, NOTE_E5, NOTE_C5
};
int introTempo[] = { //Tempo for intro melody.
8, 4, 4
};
void setup(){ //Begin setup.
lcd.begin(16, 2); //Define LCD size as 16x2.
lcd.print("Hello, world!"); //Print initial message.
}
void loop(){ //Program loop.
int yButton = analogRead(A0);//read button
lcd.setCursor(0, 1);
lcd.print(yButton);
aSound.aPlay(introMelody, sizeof(introMelody), introTempo);//Play sound.
}
