저 미세먼지 측정기 키트 구매한 중학생인데요, 근데 회로기판 다 맞는데 컴파일에러가 자꾸나는데 왜 이런건가요?

안녕하세요. 코코아팹입니다.

위에 발생한 에러는 LiquidCrystal_I2C 라이브러리가 설치되지 않아서 발생하는 에러입니다.

맨 위 메뉴바에 있는 [스케치 -> 라이브러리 포함하기 -> 라이브러리 관리] 로 들어가셔서 LiquidCrystal_I2C 로 검색하시면 결과가 쭉 나오는데요.

스크롤을 맨 밑으로 내린 후 밑에서 3번째 보시면 LiquidCrystal_I2C by Frank de Brabander 라고 있습니다.

이것을 선택 하신 후에 설치를 눌러주신 후 다시 업로드 해보시면 될 것 같습니다.

감사합니다.

말씀하신대로 라이브러리에 포함하였는데 계속 이렇게 뜨네요..ㅠㅠC:\Users\lenovo\AppData\Local\Temp\arduino_modified_sketch_748762\sketch_may31e.ino:1:31: fatal error: LiquidCrystal_I2C.h: No such file or directory

어떻게 해야할까요,,,

온습도 센서는 사용하지않고 미세먼지만 따로 사용하게끔 하는 코드는 없을까요? 만약 기존코드에서 바꾼다면 어느부분을 지우면 잘 적용될까요?

나야나 2018-09-30 21:11:02

온도와 습도의 출력값이 각가 2, 4 정도 입니다. 무엇이 잘못되엇을까요

알맹이 2018-10-02 02:37:52

미세먼지 값이 -값으로 출력이 되다가 data error=101 이라는 메세지를 뱉어 냅니다.
미세먼지 센서 문제일까요? 에러값 출력으로 인해 온도 습도값이 디스플레이에서는 변하지 않습니다.

오페라 2018-11-04 07:59:50

혹, mdf 따로 구매가능한가요??

도플러 2018-12-01 11:09:16

LCD에 불만 들어오고 글씨가 출력되지 않는다면 '지원'의 Q1에 해당하는 오류네요. 초기 설정은 0x3F이었는데 0x27로 수정 한 후 LCD에 글씨가 잘 나옵니다.

미세먼지 값이 음수로 출력되다가 시리얼 모니터에서 data error=101을 출력하고, 온도와 습도값도 변하지 않는다면 미세먼지센서의 연결을 확인해보세요. 회로도(하드웨어 메이킹 - 브레드보드 레이아웃)에 나와있는 미세먼지 센서의 선 색이 실제 센서의 선 색과 다릅니다. 쓰여진 것과 같이 선의 순서로 구분하여 브레드보드에 연결하니 정상적으로 작동하였습니다.

다들 비슷한 실수를 하나 봅니다ㅎㅎ 만들어놓고 보니 마음에 쏙 드네요~

그대로 따라서 했는데 실행까지는 됩니다.
근데 LCD에서 미세먼지 값이 너무 변화가 없어서 시리얼 모니터로 확인해봤는데
4번 정도의 먼지값이 변화를 하다가 data error = 101 이런 메세지만 계속 나오는데
원인이 뭔지 여쭤봐도 괜찮을까요?

역시 저를 실망시키지 않으시군요.흐흐

안녕하세요~
온습도 센서만 DHT22(AM2302)로 이용하여 위와 똑같이 구현하여 만들어보았습니다.
그런데 온도가 1도에 습도도 2%에서 1%정도로 나오는데 왜이렇게 나오는지 궁금합니다.
어떻게 바꿔야하는지도 알려주시면 감사하겠습니다.

또 소스코드를 보니까 data 가 미세먼지수치를 나타내는것같은데
어떤 수치인지 단위는 어떤지 궁금합니다.(소스코드를 해석하기에 제실력이 부족한것같습니다.ㅠㅠ)
마지막으로 이 data값을 이용해서 얼마 초과되면 servo motor가 동작하게 코드를 만들어보고싶은데
어떻게 해야할지 조언 부탁드립니다.
더운날씨에 정말 고생하시는데 한번만 신경써주시면 감사하겠습니다.

연결을 모두 하고 코딩값도 제대로 나왔는데 업로딩중에

보드에 업로딩중에 문제 발생. 다음을 참고하세요. http://www.arduino.cc/en/Guide/Troubleshooting#upload

이문구가 계속나오며 업로딩이 안됩니다. 이 이후에도 다시 모두다 뺏다가 다시 연결해봐도 똑같은말만나옵니다.

687.52 라는 수치가 찍히는데 저희집은 쓰레기장인가요? ㅠㅠ
연구원님들 찍히는 값은 16.52 뭐 이정도로 찍히는 걸로 보이거든요.
제 센서 불량인걸까요?

위의 두군데에서 "No such file or directiory"이라는 컴파일 에러가 나는데,
이 두가지 파일은 어디서 얻을수 있나요?
