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 -arduino.cc/en/Reference/Wire
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
GND -> GND
Loading more stuff…
Hmm…it looks like things are taking a while to load. Try again?
