Add motion, direction and orientation sensing to your Arduino project with this all-in-one 9-DOF sensor. Inside the chip are three sensors, one is a classic 3-axis accelerometer, which can tell you which direction is down towards the Earth (by measuring gravity) or how fast the board is accelerating in 3D space. The other is a 3-axis magnetometer that can sense where the strongest magnetic force is coming from, generally used to detect magnetic north.  The third is a 3-axis gyroscope that can measure spin and twist.  By combining this data you can REALLY orient yourself.\u003cbr\u003e\u003cbr\u003eWhen we saw the new LSM9DS0 from ST micro we thought - wow this could really make for a great breakout, at a very nice price! Design your own activity or motion tracker with all the data...

Attaching it to the Arduino is simple, power Vin and GND with 3-5VDC, and wire up I2C data on SCL and SDA, and you're ready to go! More advanced users can use SPI, our library has support for both. The breakout comes fully assembled and tested, with some extra header so you can use it on a breadboard. Four mounting holes make for a secure connection, and we put the popular power+data pins on one side, and the interrupt pins on the other side for a nice \u0026amp; compact breakout.\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 10px;\"\u003e\u003ca href=\"https:\/\/github.com\/adafruit\/Adafruit_LSM9DS0_Library\"\u003eCheck out our Arduino library while we finish up the tutorial.
