第12週

複習上周發出聲音

程式碼:

#define Do 523

#define Mi 659

#define So 784

void setup() {

  // put your setup code here, to run once:

  pinMode(8,OUTPUT);///設定頻率8打開

  tone(8,Do);///不給長度，一直發出聲音

  delay(500);///延遲0.5秒，Do發出0.5秒

  tone(8,Mi);

  delay(500);

  tone(8,So);

  delay(500);

  noTone(8);///靜音

}

void loop() {

  // put your main code here, to run repeatedly:

}

*2是用BUTTON*

程式碼:

#define Do 523

#define Mi 659

#define So 784

void setup() {

  // put your setup code here, to run once:

  pinMode(2,INPUT_PULLUP);///預設2被拉起來

  pinMode(8,OUTPUT);

  tone(8,Do);

  delay(500);

  tone(8,Mi);

  delay(500);

  tone(8,So);

  delay(500);

  noTone(8);

}

void loop() {

  // put your main code here, to run repeatedly:

  if(digitalRead(2)==LOW) tone(8,So,100);///按下BUTTON=2被按下，則發出聲音

}

*Arduino+p語言*

按視窗會發出聲音

Arduino:

#define Do 523

#define Mi 659

#define So 784

void setup() {

  Serial.begin(9600);

  // put your setup code here, to run once:

  pinMode(2,INPUT_PULLUP);

  pinMode(8,OUTPUT);

  tone(8,Do);

  delay(500);

  tone(8,Mi);

  delay(500);

  tone(8,So);

  delay(500);

  noTone(8);

}

void loop() {

  // put your main code here, to run repeatedly:

  while(Serial.available()>0){///有資料可送!

      Serial.read();

      tone(8,Mi,100);

    }

}

P語言:

import processing.serial.*;

Serial myPort;

void setup(){

  size(200,200);

  myPort = new Serial(this,"COM3",9600);

}

void draw(){

  

}

void mousePressed(){

  myPort.write("1");

}

按數字1.3.5發出不通聲音

Arduino:

#define Do 523

#define Mi 659

#define So 784

void setup() {

  Serial.begin(9600);

  // put your setup code here, to run once:

  pinMode(2,INPUT_PULLUP);

  pinMode(8,OUTPUT);

  tone(8,Do);

  delay(500);

  tone(8,Mi);

  delay(500);

  tone(8,So);

  delay(500);

  noTone(8);

}

void loop() {

  // put your main code here, to run repeatedly:

  while(Serial.available()>0){///有資料可送!

      int now=Serial.read();

      if(now=='1') tone(8,Do,100);

      if(now=='3') tone(8,Mi,100);

      if(now=='5') tone(8,So,100);

    }

}

P語言:

import processing.serial.*;

Serial myPort;

void setup(){

  size(200,200);

  myPort = new Serial(this,"COM3",9600);

}

void draw(){

  

}

void keyPressed(){

  if(key=='1') myPort.write("1");

  if(key=='3') myPort.write("3");

  if(key=='5') myPort.write("5");

}

void mousePressed(){

  myPort.write("1");
