The document discusses the Arduino Yùn, which is described as the perfect IoT Arduino board. It has two boards in one, combining an Arduino Leonardo-compatible microcontroller with a MIPS microprocessor that enables WiFi, USB, and card reader functionality. It also runs a custom OpenWrt Linux distribution called Linino. The Arduino Yùn can be programmed like a typical Arduino using the Arduino IDE and Bridge library, and sketches can be uploaded over WiFi. It also allows configurations and Linux terminal access through a web panel. Practical examples demonstrated include a web-enabled state control application and a motion-detecting security camera that can store photos and send alarms.

4. SPECIFICATION
A lot more than a Arduino.
Two boards in one !

5. The same
microcontroller you
can find on a Arduino
Leonardo board...

7. Oh, did I mention that there is also a custom OpenWrt Linux
distribution called Linino, at your service?

8. HOW TO USE IT?
 Classical Arduino IDE sketches
 Extensive usage of the Bridge
library
 It is possible to upload the sketch
through WiFi

9.  You can check out
configurations through a web
panel

12.  The website shows the internal state of the board.
 The user is able to modify the state of both analog and digital
outputs
 The page is refreshed asynchronously by the browser
 Each user spawns his own thread on the board: the web server
is able to ensure simple concurrency

17.  The Linino OS offers the drivers for the USB camera (kmod-video-
uvc)
 The library motion is used for the motion detection
 Very detailed configurations into /etc/motion.conf
 Offline storage of pictures as a proof of movement
