A Machine-to-Machine (M2M) system, which uses
Arduino, Android, and Wiki software, is discussed.
["proposed"?] This system consists of mobile terminals and
web sites with wiki software. A mobile terminal of the system
consists of an Android terminal and an Arduino board with
sensors and actuators. The mobile terminal reads data from
the sensors in the Arduino board and sends the data to a wiki
page. The mobile terminal also reads commands on the wiki
page and controls the actuators of the Arduino board. In
addition, a wiki page can have a program that reads the page
and outputs information such as a graph. This system realizes
an open communication forum for not only people but also for
machines.
