교수님 안녕하세요?
이전에 질문했던 temp 변동값은 해결했습니다.
추가 질문 있습니다.
1. 코드값 중에 lcd.init() 있지 않습니까? 근데 일부 시험장에서 시험치고 온 수험생들 말을 들어보니
따로 연습할때는 lcd.init()가 잘 작동되지만, 시험장에서는 안된다면서 lcd.begin(16,2) 이걸로 바꿔서
코드값 쓰라는데,, 막상 코드값 바꿔서 넣으면 메가보드가 작동이 되지 않습니다.
시험장에서도 lcd.init()로 그냥 써도 문제 없겠지요?
2. 올배움 채팅으로 동영상 하나 보내드렸는데,
유형 3번에서 sensor mode 진입하려고하면 다시 1.clock mode 화면으로 강제 전환됩니다.
진입했다가 바로 강제 전환되기도 하구요.
이전에는 잘 작동 됐던거 같은데 갑자기 안되길래 mega보드 문제인가 싶었는데
유형1,2번은 sensor mode에 정상 진입합니다.
유형3 코드값 첨부할테니 확인 부탁드립니다.
