Arduino Sketch

/* SFE_BMP180 library example sketch
 
This sketch shows how to use the SFE_BMP180 library to read the
Bosch BMP180 barometric pressure sensor.
https://www.sparkfun.com/products/11824
Hardware connections:
 
- (GND) to GND
+ (VDD) to 3.3V
 
(WARNING: do not connect + to 5V or the sensor will be damaged!)
 
You will also need to connect the I2C pins (SCL and SDA) to your
Arduino. The pins are different on different Arduinos:
 
Any Arduino pins labeled:  SDA  SCL
Uno, Redboard, Pro:        A4   A5
Mega2560, Due:             20   21
Leonardo:                   2    3
