Week12 葉正聖老師示範

今天的目標: 自製的Input 裝置

1. 先複習上週的進度: Blink 及你們做的 Knight Rider 燈
1.1. Step 1: Prepare Hardware and Software

1.2. Step 2: Try the Example Blink
http://arduino.cc/en/Guide/Windows

1.3. Step 3: Write Your Code


2. 我們來試試用 按鈕 Button 吧!
2.1. Arduino: File - Examples - 2.Digital - Button

3. 我們來試試用 蜂鳴器 來發出聲音吧!
3.1. Arduino: File - Examples - 2.Digital - toneMelody

練習用 tone() 發聲音
void setup(){
  tone(8, 440*2, 1000);
}
void loop(){

}


將 myButton 與 tone() 做結合
void setup(){
  pinMode(2, INPUT_PULLUP);//no resistor
  pinMode(13, OUTPUT);
}
void loop(){
  if(digitalRead(2)==HIGH){
    digitalWrite(13, HIGH);
    tone(8, 440*2, 300);
  }else{
    digitalWrite(13, LOW);
    noTone(8);
  }
}

將 myButton 與 PC 用 Serial 做連結 (參考 Processing-Examples-Libraries-Serial-SimpleRead)
void setup(){
  pinMode(2, INPUT_PULLUP);//no resistor
  pinMode(13, OUTPUT);
  Serial.begin(9600);/////Serial
}
void loop(){
  if(digitalRead(2)==HIGH){
    digitalWrite(13, HIGH);
    tone(8, 440*2, 300);
  }else{
    digitalWrite(13, LOW);
    Serial.write('L'); //////Serial
    noTone(8);
  }
}

改裝 Melody 變成可以因為按鍵而中斷
#include "pitches.h"
int melody[] = {NOTE_G4, NOTE_E4,NOTE_E4, 0, NOTE_F4, NOTE_D4,NOTE_D4, 0,
  NOTE_C4, NOTE_D4,NOTE_E4,NOTE_F4,NOTE_G4,NOTE_G4,NOTE_G4,0,
  NOTE_G4, NOTE_E4,NOTE_E4, 0, NOTE_F4, NOTE_D4,NOTE_D4, 0,
  NOTE_C4, NOTE_E4,NOTE_G4,NOTE_G4,NOTE_E4,0
};
int noteDurations[] = { 4,4,2,16, 4,4,2,16, 4,4,4,4, 4,4,4,4,  4,4,2,8, 4,4,2,8, 4,4,4,4, 2,4};

void setup(){
  pinMode(2, INPUT_PULLUP);
}
void loop(){
  for (int thisNote = 0; thisNote < 30; thisNote++) {
    if(digitalRead(2)==LOW){
      noTone(8); break;
    }
    int noteDuration = 1000/noteDurations[thisNote];
    tone(8, melody[thisNote],noteDuration);
    int pauseBetweenNotes = noteDuration * 1.30;
    delay(pauseBetweenNotes);
    noTone(8);
  }
}
