Код Arduino / не хватило памяти / arduino uno

Question

Я пытаюсь сделать проект Arduino, который имеет 3 функции; играть на фортепианной клавиатуре, воспроизводить произвольную песню, а также играть и записывать для воспроизведения. До сих пор я встречал все три из этих функций. Проблема в том, что у меня есть хранилище на моем Arduino, я полностью исчерпал пространство и больше не могу вставить код musi c внутрь. На данный момент у меня есть только одна песня, но я хочу добавить еще. Должен ли я получить Arduino Mega или редактировать код? -Спасибо!

Вот мой код:

#include "pitches.h"
#include <LiquidCrystal.h>
LiquidCrystal lcd(12, 11, 5, 4, 3 ,2);
int notes[] = { NOTE_G4, NOTE_D6};

int button_music = 0;
int button2 =0;
int randNumber;

int key1 = 0;
int key2 = 0;
int recorded_button[200];
int recorded_time[200];
int pev_button;
char button = 0;
char button_index = 0;
int note_time;
unsigned long start_time;
char time_index;






void setup() {
  Serial.begin(9600);
  lcd.begin(16,2);
  pinMode(A5, OUTPUT);
  pinMode(A4, OUTPUT);
  pinMode(6,OUTPUT);
  pinMode(7,OUTPUT);
  pinMode(8, INPUT);
  pinMode(9,INPUT);
  // put your setup code here
}

void loop() {
 button_music = digitalRead(A4);
 button2 = digitalRead(A5);
 key1 = digitalRead(7);
 key2 = digitalRead(6);
 lcd.setCursor(0,0);
 lcd.print("Press button to"); 
 lcd.setCursor(0,1);
 lcd.print("play random song");
 if(button_music == HIGH) {
      lcd.clear();
      lcd.setCursor(0,0);
      lcd.print("In Progress...");
      delay(5000);
      randNumber = random(1,4);
      Serial.println(randNumber);
      if(randNumber == 1) {

        delay(1000);
