Week11 uno版自行改寫程式碼
1.讓燈逐漸亮起來
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);
}
}
2.範例

修改範例,改成會照著旋律亮燈
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 }; ///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);
}
}

透過按鈕修改音樂(但要等正在撥的撥完QQ
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}; //第一首歌
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 }; //第二首歌
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);
}
}

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);
}
}
}
4.修改前一範例
按鈕一按就可以卡歌了唷(ノ>ω<)ノ
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=1; ///更改歌的變數
void loop()
{
delay(tempo/2);
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
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 = 1; break;
} ///卡歌,換前一首
delay(tempo / 2);
}
}
}
