1.按按鍵出聲音

CODE:

void setup() {
  pinMode(8, OUTPUT);
  pinMode(2, INPUT_PULLUP);

}

void loop() {
  if(digitalRead(2)==LOW )tone(8, 520, 1000);
  else noTone(8);
}

2.按按鍵出聲音Mi

CODE:


int Do = 523;
int Re = 587;
int Mi = 659;
void setup() {
  pinMode(8, OUTPUT);
  pinMode(2, INPUT_PULLUP);

}

void loop() {
  if(digitalRead(2)==LOW ) tone(8, Mi, 1000);
  else noTone(8);

}

3.按按鍵出  "小蜜蜂"

CODE:


int Do = 523;
int Re = 587;
int Mi = 659;
int Fa = 698;
int So = 784;
int a[13] = {So,Mi,Mi,Fa,Re,Re,Do,Re,Mi,Fa,So,So,So};
int i=0;
bool UP = true;
void setup() {
  pinMode(8, OUTPUT);
  pinMode(2, INPUT_PULLUP);

}

void loop() {
    if(UP && digitalRead(2)==LOW ){
    tone(8, a[i],200);
    UP = false;
    i = (i+1)%13;
  }
  else{
   UP = true;
  }
  delay(100);
 
}
