Iduino Yun is a ideal IoT device for Internet of Things projetcs. It is a compatible / replacement product for Arduino Yun. It works with Arduino IDE with version higher than 1.5.4.

The Iduino Yun is a microcontroller board based on the ATmega32u4 and the Atheros AR9331. The Atheros processor supports a Linux distribution based on OpenWrt named OpenWrt-Yun. The board has built-in Ethernet and WiFi support, a USB-A port, micro-SD card slot, 20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16 MHz crystal oscillator, a micro USB connection, an ICSP header, and a 3 reset buttons.

The Iduino Yun is similar to the Arduino Leonardo in that the ATmega32u4 has built-in USB communication, eliminating the need for a secondary processor. This allows the Yun to appear to a connected computer as a mouse and keyboard, in addition to a virtual (CDC) serial / COM port.

The Bridge library facilitates communication between the two processors, giving Arduino sketches the ability to run shell scripts, communicate with network interfaces, and receive information from the AR9331 processor. The USB host, network interfaces and SD card are not connected to the 32U4, but the AR9331, and the Bridge library also enables the Arduino to interface with those peripherals.



Features

  • Open source Linux (OpenWrt) onboard
  • Compatible with Arduino IDE 1.5.4 or later, user can program, debug or upload sketches to the Arduino board via the Arduino IDE.

Quick Start of Iduino Yun

This chapter shows how to run the first sketch of Iduino Yun.

Connect to Iduino Yun

Power on Iduino Yun, after the system runs, it will generate a WiFi network with SSID : I duino-A84041XXXXXX.

Iduino Yun Generate an unsecure WiFi network

Use your PC to connect to this unsecure WiFi netowrk. Your PC will get DHCP from Yun. Your PC will get an IP 192.168.240.x and the Iduino Yun will have the IP 192.168.240.1



Open Arduino IDE and configure right Profile

Open Arduino IDE and choose the profile Tools --> Boards --> Arduino Yun. Choose the ports to "Iduino at 192.168.240.1"

Choose Yun profile



Upload Bridge example

This example for the Arduino Yun shows how to use the Bridge library to access the digital and analog pins on the board through REST calls. It demonstrates how you can create your own API when using REST style calls through the browser.

Possible commands created in this shetch:

 "YUNs_IP/arduino/digital/13"     -> digitalRead(13)
 "YUNs_IP/arduino/digital/13/1"   -> digitalWrite(13, HIGH)
 "YUNs_IP/arduino/analog/2/123"   -> analogWrite(2, 123)
 "YUNs_IP/arduino/analog/2"       -> analogRead(2)
 "YUNs_IP/arduino/mode/13/input"  -> pinMode(13, INPUT)
 "YUNs_IP/arduino/mode/13/output" -> pinMode(13, OUTPUT)

In Arduino IDE, Select example File-->Examples-->Bridge-->Bridge . Click Upload , Arduino IDE will compile this example and upload to Yun. During the upload, Arduino IDE will pop up a window for asking the password. type password iduino here. and continue upload.

upload sketch to Yun





Test the sketch

After upload, user can open the web broswer and use it to Read/Write the I/Os of Yun.

type password for Bridge sketch

Notice: Yun will ask for password at the first connect via Web. The user name is root and password is iduino.

more info about this sketch please refer this link: Explain of Bridge Example
