To build the code with Arduino IDE, you must install some libraries. The libraries needed are in src/libs/libs.zip. You need to unzip this in your Arduino Libraries folder (on Windows: <My Documents>\Arduino\libraries). See Adafruit's All About Arduino Libraries tutorial for more details.
The libraries used are:
- Adafruit_Sensor: Core Adafruit Arduino sensors framework.
- Adafruit_BMP085_Unified: Driver for BMP085 pressure sensor.
- Adafruit_ADXL345: Driver for ADXL345 accelerometer.
