Arduino Library

The Soldered BMA400 Accelerometer library talks to the breakout over I2C. You include BMA400-SOLDERED.h and create a Soldered_BMA400 object; the library builds on SparkFun's BMA400 Arduino library and Bosch's BMA400 driver, so the same object also reads the step counter and sets up the chip's interrupts.
