Arduino Yún is the one of the best prototyping boards used for building Internet of Things applications. Unlike others, Yún is smaller in size and also enabled with inbuilt WIFI connectivity and Linux running machine. Yún consists of two IC's Atheros AR9331 runs OpenWRT-Yún Linux build with OpenWRT Wireless Stack and a 8-Bit Atmega-32u4 used to hook up the sensors, Actuators,etc., for collecting the sensor DATA. So with this we can collect the data and push to the cloud API. Both the IC's are connected with a BRIDGE using serial port. OpenWRT-Yún Linux mainly built for embedded platform comes with inbuilt Python 2.7.4 installed and you can also install ruby, node or PHP as you prefer. Once configured with the wifi network, the Atmega 32u4 can be programmed via wifi as well as usb port. PREREQUISITES Format the SD Card to work with Arduino Yún storage.
