先根據之前的步驟 將 驅動程式裝好

將這個網址的程式碼複製 使用
讓LED逐一亮起的程式
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);
}
}
修改成會亮對應LED程式
int piezoPin = 8;
int length = 15;
char notes[] = "ccggaag ffeeddc ggffeed ggffeed ccggaag ffeeddc "; // a space represents a rest
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 }; ///加入陣列
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 ); ///在播聲音之前,把對應的LED亮起
playTone(tones[i], duration);
digitalWrite( LED[i], LOW ); ///在播聲音之後,把對應的LED暗掉
}
}
}
void setup()
{
//pinMode(piezoPin, OUTPUT);
for(int i=2;i<=13;i++) pinMode( i, OUTPUT ); ///在執行之前,把每個腳位,都設成OUTPUT,才會亮、發聲音
}
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);
}
}
透過按鈕改音樂(需要按著等到前個音樂結束)
int piezoPin = 8;
int button = 2; ///把Button切換到pin2
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}; ///另一首歌
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);
}
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);
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);
delay(tempo / 2);
}
}
}
一按切換

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)
{

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=1; ///更改歌的變數
void loop()
{
delay(tempo/2); //int sensorVal = digitalRead(button); 把舊的註解掉,改成延遲幾秒再執行
if (now==1)
{
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 = 2; break;} ///卡歌,換下一首
delay(tempo / 2);
}
}
else
{
