라즈베리파이 프로젝트 피아노 만들기 -마무리 편
안녕하세요!! 첫 글을 작년 초에 작성하였는데.. 전자과 3학년 정말 너무너무 바빴습니다..ㅠㅠ
결국 지금 쓰게 되네요 허허.. 저번에 이어 피아노가 구동되는 과정을 간략히 설명드리고 시연영상을 보여드리고자 합니다.
MCU는 라즈베리파이를 이용했기 때문에 파이썬 언어를 사용하여 코딩을 작성하였는데요.
각 건반의 아래에 있는 스위치에는 각 각 다른 음역대의 주파수 소리를 내도록 설정되어 있습니다. 스위치를 누르면 부저 스피커가 위의 사진처럼 주파수에 따른 소리를 내게 되는데 마치 도레미파솔라시도 의 소리와 같게 되는 겁니다.
사실 더 고퀄리티로 만들고 싶다면 부저의 소리가 아닌 mp3로 변환된 소리를 스위치가 눌릴 때 넣는 것이 좋을 겁니다. 예를 들면 if(GPIO(22)=HIGH) > play(솔 소리.mp3) 뭐 이런 느낌으로요. 하지만 프로젝트인 만큼 센서나 회로 소자에 대한 배움이 있어야한다고 생각했습니다.
세부 기능으로는 각 건반을 누를 때 LCD에서 계이름이 표시되고 옥타브를 조절하여 활용할 수 있습니다. 또한 이전 영상에서 보신 것 처럼 검정색 판을 열면 조도 센서가 작동하여 지정한 노래가 나오게됩니다.
각 건반은 빠른 반응을 위해 인터럽트 기능을 사용하였고, 아직 파이썬이 서투신 분은 하드코딩으로 if문을 반복하여 구현할 수 있지만 이 김에 class문을 배워서 코드를 정리해보는 시간을 가지는 것도 좋다고 생각합니다. 객체지향을 활용하면 코드가 간결 및 수정이 용이해져서 차후에 많은 도움이 될거에요!!
너무 옛날에 한거라서 코드가 완전 정리가 안되어있긴합니다만.. 혹시 필요하신 분들을 위해 코드도 올려볼게요~~

None아 .. 완성 영상이 있는 줄 알았는데.. 전부 날아갔더라고요 ㅠㅠ 그래서 3D 프린터가 완성되기 이전에 규격이 덜 맞았던 프로토타입 연주 영상밖에 없습니다. ㅠㅠㅠ 죄송해요
다음 영상은 옥타브를 변경하는 모습이에요.!!
아.. 너무 지저분해요 ㅠㅠ 정말 이쁘게 연주도하고 조도 센서를 열면 제가 준비한!!! 이누야사에 시대를 초월한 마음이 연주되는 모습을 보면.. 마음이 멀어지는 .. 아쉽네요 ㅎㅎ 영상을 찾게되거나 지금 있는 피아노에 라즈베리를 다시 연결할 시간이 된다면 이 글에 영상을 추가 기재해보겠습니다!!
아무튼 ㅠㅠ 피아노 만들기 프로젝트 초보자, 중급자 분들에게 정말 추천합니다. 이유를 간략히 말씀드리면 회로 구성, 납땜, 파이썬 학습, 각 종 센서 및 소자 사용, 3D 프린터 사용 등 정말 다양한 경험을 할 수 있고 버리지 않고 소장하여도 정말 기쁩니다. 만약 3D 프린터를 만들 여건이 안되신다면 빵판에다가 또는 우드락을 잘라서 구현할 수도 있지 않을까요~~?
도움이 되셨다면 공감과 댓글~~ 다음에 봐요 안녕 ^~^~~
