From the project

한글시계 v2 - v1을 바탕으로 완전히 새롭게 만드는 v2

'이야 남의 것 배껴서 똑같이 만들었는데 내가 응용해서 만든 것도 하나 있어야지 않겠나...' \ 그래서 만들게 된 한글시계 v2 이다. \ -사실 말만 v2이지 상당히 다른 구조를 가지고 있다.

모든 함수는 각자의 기능에 충실하게 작성되어야 하며, 함수 용도 외의 타용도의 코드가 작성되면 안 된다. 반드시 해당 기능만 있어야 한다.

아두이노 내부의 전체 순서를 결정하는 time 변수는 이름을 internal_millis 내지는 '내부의 시간기준'이란 뜻을 가질 수 있는 이름으로 변경하기

한글시계 온습도 표시 시에 온도 및 습도(단위)는 네오픽셀 색깔을 다르게 하자.\ 색깔이 같으면 숫자 읽을 때 햇갈릴 수도 있을 듯

스위치 디바운싱을 소프트웨어로 처리하지말고 하드웨어로 처리하자. 그럼 얼마나 편하겠니...
