/***************************************************************************
  This is a library for the BME280 humidity, temperature & pressure sensor

  Designed specifically to work with the Adafruit BME280 Breakout
  ----> http://www.adafruit.com/products/2650

  These sensors use I2C or SPI to communicate, 2 or 4 pins are required
  to interface.

안녕하세요 메카솔루션입니다.

==================================

WiDo 보드를 사용하고 있습니다.

얼마전에 주문했었습니다, 주문번호 1474276999622

I2C 및 SPI 방법으로 해봤습니다.

둘다 똑같은 값만 나오고 있습니다.
