Detailed Description

This is part of Adafruit's MPL3115A2 driver for the Arduino platform. It is designed specifically to work with the Adafruit MPL3115A2 breakout: https://www.adafruit.com/products/1893

These sensors use I2C to communicate, 2 pins (SCL+SDA) are required to interface with the breakout.

Adafruit invests time and resources providing this open source code, please support Adafruit and open-source hardware by purchasing products from Adafruit!
