讓LED依序亮起















(1) 輸入程式碼讓LED依序亮起

程式碼 : 

void setup() {
  for(int i=2;i<=13;i++){
    pinMode(i,OUTPUT);
  }
}

void loop() {
  for(int i=2;i<=13;i++){
    digitalWrite(i,HIGH);
    delay(300);
  }

  for(int i=2;i<=13;i++){
    digitalWrite(i,LOW);
  }
}


聲音與LED的控制

(1) 至連結複製程式碼並執行

(2) 加入程式碼讓LED依音符亮起

程式碼 : 

int piezoPin = 8;
int length = 15;
char notes[] = "ccggaag ffeeddc ggffeed ggffeed ccggaag ffeeddc ";
int beats[] = { 1, 1, 1, 1, 1, 1, 2, 1, 1, 1, 1, 1, 1, 2, 4 };
int tempo = 300;

void playTone(int tone, int duration)
{
  for (long i = 0; i < duration * 1000L; i += tone * 2)
  {
    digitalWrite(piezoPin, HIGH);
    delayMicroseconds(tone);
    digitalWrite(piezoPin, LOW);
    delayMicroseconds(tone);
  }
}

void playNote(char note, int duration)
{
  int LED[]={2,3,4,5,6,7,9,10};//第一行
  char names[] = { 'c', 'd', 'e', 'f', 'g', 'a', 'b', 'C' };
  int tones[] = { 1915, 1700, 1519, 1432, 1275, 1136, 1014, 956 };
  for (int i = 0; i < 8; i++)
  {
    if (names[i] == note)
    {
      digitalWrite(LED[i],HIGH);//第二行
      playTone(tones[i], duration);
      digitalWrite(LED[i],LOW);//第三行
    }
  }
}

void setup()
{
  // pinMode(piezoPin, OUTPUT);
 for(int i=2;i<=13;i++)pinMode(i,OUTPUT);//第四行
}

void loop()
{
  for (int i = 0; i < length; i++)
  {
    if (notes[i] == ' ')
    {
      delay(beats[i] * tempo);
    } else
      playNote(notes[i], beats[i] * tempo);
    delay(tempo / 2);
  }
}

int piezoPin = 8;
int length = 15;
char notes[] = "ccggaag ffeeddc ggffeed ggffeed ccggaag ffeeddc "; 
int beats[] = { 1, 1, 1, 1, 1, 1, 2, 1, 1, 1, 1, 1, 1, 2, 4 };
int tempo = 300;

void playTone(int tone, int duration)
{
  for (long i = 0; i < duration * 1000L; i += tone * 2)
  {
    digitalWrite(piezoPin, HIGH);
    delayMicroseconds(tone);
    digitalWrite(piezoPin, LOW);
    delayMicroseconds(tone);
  }
}

void playNote(char note, int duration)
{
  int LED[]={3,4,5,6,7,9,10,11};//修改
  char names[] = { 'c', 'd', 'e', 'f', 'g', 'a', 'b', 'C' };
  int tones[] = { 1915, 1700, 1519, 1432, 1275, 1136, 1014, 956 };
  for (int i = 0; i < 8; i++)
  {
    if (names[i] == note)
    {
      digitalWrite(LED[i],HIGH);
      playTone(tones[i], duration);
      digitalWrite(LED[i],LOW);
    }
  }
}

void setup()
{
  //pinMode(piezoPin, OUTPUT);
  for(int i=3;i<=13;i++)pinMode(i,OUTPUT);//修改
  pinMode(2,INPUT_PULLUP);//修改
}

void loop()
{
  for (int i = 0; i < length; i++)
  {
    if (notes[i] == ' ')
    {
      delay(beats[i] * tempo);
    } else
      playNote(notes[i], beats[i] * tempo);
    delay(tempo / 2);
  }
}

按按鈕換歌

(1) 至連結複製程式碼

連結 :https://makeruno.com.my/changing-melody-with-push....../

(2)加入程式碼即可卡歌

程式碼 :

void playNote(char note, int duration)
{
  char names[] = { 'c', 'd', 'e', 'f', 'g', 'a', 'b', 'C' };
  int tones[] = { 1915, 1700, 1519, 1432, 1275, 1136, 1014, 956 };
  for (int i = 0; i < 8; i++)
  {
    if (names[i] == note)
    {
      playTone(tones[i], duration);
    }
  }
}

void setup()
{
  pinMode(piezoPin, OUTPUT);
  pinMode(button, INPUT_PULLUP);
}

void loop()
{
  int sensorVal = digitalRead(button);
  if (sensorVal == HIGH)
  {
    for (int i = 0; i < length; i++)
    {
      if (ttlsnotes[i] == ' ')
      {
        delay(ttlsbeats[i] * tempo);
      }
      else
        playNote(ttlsnotes[i], ttlsbeats[i] * tempo);

      if(digitalRead(button)==LOW)break;  //可以卡歌，按下按鈕變LOW
      delay(tempo / 2);
    }
  }
  else
  {
    for (int i = 0; i < lengths; i++)
    {
      if (jbnotes[i] == ' ')
      {
        delay(jbbeats[i] * tempo);
      }
      else
        playNote(jbnotes[i], jbbeats[i] * tempo);
      if(digitalRead(button)==LOW)break; //可以卡歌，按下按鈕變LOW
      delay(tempo / 2);
    }
  }
}

(3) 上面方法切了一次歌就沒辦法再切了，所以修改程式碼讓使用者可以隨時切換2首歌

程式碼 :

int piezoPin = 8;
int button = 2;
int lengths = 26;
char jbnotes[] = "eeeeeeegcde fffffeeeeddedg";
int jbbeats[] = { 1, 1, 2, 1, 1, 2, 1, 1, 1, 1, 4, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 2, 2};
int length = 15;
char ttlsnotes[] = "ccggaag ffeeddc ggffeed ggffeed ccggaag ffeeddc ";
int ttlsbeats[] = { 1, 1, 1, 1, 1, 1, 2, 1, 1, 1, 1, 1, 1, 2, 4 };
int tempo = 300;

void playTone(int tone, int duration)
{
  for (long i = 0; i < duration * 1000L; i += tone * 2)
  {
    digitalWrite(piezoPin, HIGH);
    delayMicroseconds(tone);
    digitalWrite(piezoPin, LOW);
    delayMicroseconds(tone);
  }
}

void playNote(char note, int duration)
{
  char names[] = { 'c', 'd', 'e', 'f', 'g', 'a', 'b', 'C' };
  int tones[] = { 1915, 1700, 1519, 1432, 1275, 1136, 1014, 956 };
  for (int i = 0; i < 8; i++)
  {
    if (names[i] == note)
    {
      playTone(tones[i], duration);
    }
  }
}

void setup()
{
  pinMode(piezoPin, OUTPUT);
  pinMode(button, INPUT_PULLUP);
}
int now=0;// 0:小星星 1:聖誕歌
void loop()
{
  delay(tempo/2);//改寫
  //int sensorVal = digitalRead(button);
  //if (sensorVal == HIGH)
  if(now==0)//改寫
  {
    for (int i = 0; i < length; i++)
    {
      if (ttlsnotes[i] == ' ')
      {
        delay(ttlsbeats[i] * tempo);
      }
      else
        playNote(ttlsnotes[i], ttlsbeats[i] * tempo);

      if(digitalRead(button)==LOW){now=1; break;}
         //可以卡歌，按下按鈕變LOW//now變1 聖誕歌
      delay(tempo / 2);
    }
  }
  else
  {
    for (int i = 0; i < lengths; i++)
    {
      if (jbnotes[i] == ' ')
      {
        delay(jbbeats[i] * tempo);
      }
      else
        playNote(jbnotes[i], jbbeats[i] * tempo);
      if(digitalRead(button)==LOW){now=0; break;}
        //可以卡歌，按下按鈕變LOW//now變0 小星星
      delay(tempo / 2);
    }
  }
}
