(蓋掉上禮拜程式碼)

void setup() {
// put your setup code here, to run once:
pinMode(8,OUTPUT);//8:buzzer
pinMode(2,INPUT_PULLUP);//2:makerUNO的按鈕
}
void loop() {
// put your main code here, to run repeatedly:
if(digitalRead(2)==LOW)tone(8,520,1000);
else noTone(8);
}
2.按按鈕發出指定音符音調

去範例程式中對照指定音符對應數字(檔案->範例->02 ->toneMelody)

int Do=523;
int Re=587;
int Mi=659;
void setup() {
// put your setup code here, to run once:
pinMode(8,OUTPUT);//8:buzzer
pinMode(2,INPUT_PULLUP);//2:makerUNO的按鈕
}
void loop() {
// put your main code here, to run repeatedly:
if(digitalRead(2)==LOW)tone(8,Mi,1000);
else noTone(8);
}
3.用陣列播放一首歌

int Do=523;
int Re=587;
int Mi=659;
int So=784;
int Fa=698;
int song[13]={So,Mi,Mi,Fa,Re,Re,Do,Re,Mi,Fa,So,So,So};
int now=0;
bool UP=true;
void setup() {
// put your setup code here, to run once:
pinMode(8,OUTPUT);//8:buzzer
pinMode(2,INPUT_PULLUP);//2:makerUNO的按鈕
}
void loop() {
// put your main code here, to run repeatedly:
if(UP&&digitalRead(2)==LOW){tone(8,song[now],1000);
UP=false;
now=(now+1)%9;//避免陣列song[now]超過而當掉
}
else {
noTone(8);
UP=true;
}
delay(300);
}
4.接單芯線發出聲音

void setup() {
// put your setup code here, to run once:
for(int i=2;i<=13;i++){
pinMode(i,INPUT_PULLUP);
}
pinMode(8,OUTPUT);//8:buzzer
}
void loop() {
// put your main code here, to run repeatedly:
if(digitalRead(2)==LOW){tone(8,523,200);}
if(digitalRead(3)==LOW){tone(8,587,200);}
if(digitalRead(4)==LOW){tone(8,659,200);}
if(digitalRead(5)==LOW){tone(8,698,200);}
if(digitalRead(6)==LOW){tone(8,784,200);}
if(digitalRead(7)==LOW){tone(8,880,200);}
//8要避開,因為他要output用buzzer發聲(8,....)
if(digitalRead(9)==LOW){tone(8,988,200);}
if(digitalRead(10)==LOW){tone(8,1047,200);
}
}
5.網路連線


找電腦ip位址
import processing.net.*; Server server; void setup(){ size(300,300); server=new Server(this,6666); } void draw(){ Client thisClient =server.available(); while(thisClient !=null){ String now=thisClient.readString(); if(now!=null) println("Server received:"+now); } }
import processing.net.*; Client client; void setup(){ client = new Client(this, "120.125.70.53", 6666); client.write("Hello"); } void draw(){ }
