아두이노 레오나르도로 볼륨 컨트롤러

1 minute read

아두이노 레오나르도로 PC나 Mac의 볼륨 컨트롤러를 만들었다.

  1. https://github.com/NicoHood/HID 여기서 라이브러리 zip 파일 다운 받기
  2. 아두이노 IDE 메뉴 -> Sketch  -> Include Library -> Add .zip file 해서 라이브러리 추가
  3.  코드 작성

[code language=”cpp”]
#include “HID-Project.h”

#define outputA 6
#define outputB 7
#define button 8
int counter = 0;
int aState;
int aLastState;
void setup() {
pinMode (outputA,INPUT);
pinMode (outputB,INPUT);
pinMode (button, INPUT_PULLUP);
Consumer.begin();

//Serial.begin (9600);

// Reads the initial state of the outputA
aLastState = digitalRead(outputA);
}
void loop() {
aState = digitalRead(outputA); // Reads the “current” state of the outputA
// If the previous and the current state of the outputA are different, that means a Pulse has occured
if (aState != aLastState){
// If the outputB state is different to the outputA state, that means the encoder is rotating clockwise
if (digitalRead(outputB) != aState) {
counter ++;
Consumer.write(MEDIA_VOLUME_UP);
} else {
counter –;
Consumer.write(MEDIA_VOLUME_DOWN);
}
//Serial.print(“Position: “);
//Serial.println(counter);
}
aLastState = aState; // Updates the previous state of the outputA with the current state

if (!digitalRead(button)) {
//Serial.println(“Button Pressed”);
Consumer.write(MEDIA_VOLUME_MUTE);
delay(500);
}
}

여기서 확인했고볼륨 컨트롤은
