今天想要用BMP180這塊SENSOR可是我照著這影片裡面操作


偵錯沒問題也可以"燒錄"，ANALOG IN 也沒接錯


電源3.3V 5V 也都試過了

LIBRARY也有匯入

SENSOR 傳給電腦的數值一直是0度，想請問各位前輩有沒有類似經驗可以提供






附上程式碼


#include <Wire.h>
#include "Adafruit_BMP085.h"

/***************************************************
  This is an example for the BMP085 Barometric Pressure & Temp Sensor

// Connect VCC of the BMP085 sensor to 3.3V (NOT 5.0V!)
// Connect GND to Ground
// Connect SCL to i2c clock - on '168/'328 Arduino Uno/Duemilanove/etc thats Analog 5
// Connect SDA to i2c data - on '168/'328 Arduino Uno/Duemilanove/etc thats Analog 4
// EOC is not used, it signifies an end of conversion
// XCLR is a reset pin, also not used here
