只要連接上就會發出聲音。
並且去下載Arduino
讓第13個燈泡亮
pinMode(13,OUTPUT);
digitalWrite(13,HIGH);

讓全部的燈泡都亮
for(int i=2;i<=13;i++){
pinMode(i,OUTPUT);
digitalWrite(i,HIGH);
}
按下按鈕會燈熄滅，不按會亮
void setup() {
pinMode(2, INPUT_PULLUP); //把BUTTON(2)打開
for(int i=3;i<=13;i++){ //2是button,所以output從3開始
pinMode(i,OUTPUT); //把led(3...13)開關打開
}
}
bool bLightHIGH = true;
void loop() {
if(digitalRead(2) == HIGH)bLightHIGH = true;
else bLightHIGH = false; //按下去變low
for(int i=3;i<=13;i++){
if(bLightHIGH) digitalWrite(i, HIGH);
else digitalWrite(i, LOW);
}
}
可以使用內建的程式來參考
按下按鈕後會撥放小蜜蜂

按下鍵盤數字會發出相對應聲音
