Bridge Library for Arduino Yún

The Arduino Yún has two processors on board. One is an ATmega32U4 like on the Arduino ../stream/Stream, and many of the methods should be familiar from Serial and other derivatives of Stream.

Bridge commands from the 32U4 are interpreted by Python on the AR9331. Its role is to execute programs on the GNU/Linux side when asked by Arduino, provide a shared storage space for sharing data like sensor readings between the Arduino and the Internet, and receiving commands from the Internet and passing them directly to the Arduino.

Bridge allows communication in both directions, acting as an interface to the the Linux command line. For a brief explanations of the terminal and executing commands on Linux see here.

To become familiar with the Yún, please see the WebSockets to communicate. you can find more about Spacebrew

    To become familiar with the Yún, please see the through their online documentations.

    Examples
