[아두이노] 피아노 연습

기본적으로 아두이노에... 기본적인 MIDI가 있기 때문에 그 MIDI를  바탕으로 한번 연습해본 거 이다.!!!

아래 코드는 각 음마다 함수처리를 한 것 이다.

int speakpin =9;

int pitch=0;

void setup()

{

  pinMode(1,INPUT);

  pinMode(2,INPUT);

  pinMode(3,INPUT);

  pinMode(4,INPUT);

  pinMode(5,INPUT);

  

  pinMode(speakpin,OUTPUT);

}

void loop()

{

  if(digitalRead(1) ==0)

  {

     Do(); 

  }

  if(digitalRead(2) ==0)

  {

      re();

  }

  if(digitalRead(3) ==0)

  {

     mi();

  }

  if(digitalRead(4) ==0)

  {

     la();

  }

  if(digitalRead(5) ==0)

  {

    sol();

  }

  

}

void sol()

{

  pitch = 1276 - analogRead(0);

  digitalWrite(speakpin,1);

  delayMicroseconds(pitch);

  digitalWrite(speakpin,0);

  delayMicroseconds(pitch);

}

void la()

{

  pitch = 1137 - analogRead(0);

  digitalWrite(speakpin,1);

  delayMicroseconds(pitch);

  digitalWrite(speakpin,0);

  delayMicroseconds(pitch);

}

void Do()

{

  pitch = 955 - analogRead(0);

  digitalWrite(speakpin,1);

  delayMicroseconds(pitch);

  digitalWrite(speakpin,0);

  delayMicroseconds(pitch);

}

void re()

{

  pitch = 852 - analogRead(0);

  digitalWrite(speakpin,1);

  delayMicroseconds(pitch);

  digitalWrite(speakpin,0);

  delayMicroseconds(pitch);

}

void mi()

{

  pitch = 759 - analogRead(0);

  digitalWrite(speakpin,1);

  delayMicroseconds(pitch);

  digitalWrite(speakpin,0);

  delayMicroseconds(pitch);

}
