6. 문제점 및 에러 내용
오렌지 wifi 를 사용하고 있구요.
네오픽셀 led 15씩 4줄 사용합니다.
Adafruit_NeoPixel strip = Adafruit_NeoPixel(15, 5, NEO_GRB + NEO_KHZ800);
Adafruit_NeoPixel strip2 = Adafruit_NeoPixel(15, 6, NEO_GRB + NEO_KHZ800);
Adafruit_NeoPixel strip3 = Adafruit_NeoPixel(15, 9, NEO_GRB + NEO_KHZ800);
Adafruit_NeoPixel strip4 = Adafruit_NeoPixel(15, 10, NEO_GRB + NEO_KHZ800);
그리고 기상청에서 강수확률을 받아오고
서버 끊고 다시 airkorea 에 접속하여 미세먼지 등급을 받아오려고 합니다.
그런데 값이 않읽혀 집니다. 또 네오픽셀 갯수를 2개,2개,2개,2개 씩으로 조정하면
값을 받아옵니다........
왜그런 거죠??
그리고 wifi 를 연결을 끊었다가 다시 연결하는 함수가 있을까요??
