RedBot

/***********************************************************************
 * Exp8_1_AccelerometerRead -- RedBot Experiment 8.1
 * 
 * Measuring speed, velocity, and acceleration are all key
 * components to robotics. This first experiment will introduce
 * you to using the Accelerometer sensor on the RedBot.
 * 
 * Hardware setup:
 * You'll need to attach the RedBot Accelerometer board to hader on the upper
 * right side of the mainboard. See the manual for details on how to do this.
 * 
 * This sketch was written by SparkFun Electronics, with lots of help from 
 * the Arduino community. This code is completely free for any use.

 * Revised, 31 Oct 2014 B. Huang

 * 8 Oct 2013 M. Hord
 * 
 * This experiment was inspired by Paul Kassebaum at Mathworks, who made
 * one of the very first non-SparkFun demo projects and brought it to the
 * 2013 Open Hardware Summit in Boston. Thanks Paul!
