This is a demo of how Arduino speaks I2C/TWI device using the Wire.h library
(I looked up.. TWI means Two Wire Interface.. pfft.. Am i the only one unimpressed by how un-profound tech acronyms are?) The Arduino Uno uses pins A4 for data and A5 for Clock. For other Arduinos check

In this experiment with the Keepon (disassembled) is set up as a Writer and the Arduino is setup as Reader.

Keepon's Microcontroller has 4 pads Vin, Clock, Data, Ground. Hook it up to the arduino UNO

Keepon -> Arduino
Vin -> A0
Clock -> A5
Data -> A4
