+/*************************************************** 
+  This is an example for the BMP085 Barometric Pressure & Temp Sensor
+  Designed specifically to work with the Adafruit BMP085 Breakout 
+  ----> https://www.adafruit.com/products/391
+  These displays use I2C to communicate, 2 pins are required to  
+  interface
+  Adafruit invests time and resources providing this open source code,

+// 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
