  El Arduino Yun es una placa electrónica basada en el procesador ATmega32u4 y el procesador Atheros AR9331 que corre Linino, una versión personalizada de una distribución Linux llamada OpenWrt, especialmente diseñado para ejecutarse en SBCs o microcontroladores. También cuenta con conexión WiFi, Ethernet y una ranura microSD para el almacenamiento.

La Yun se distingue de otras…

ArduinoYun的相關範例在網路上越來越多人分享，想必大家常常遇到按照步驟與Temboo連線，但是Dropbox卻沒有任何回應。

首先可以來Activity的LOG來看Temboo是否有資料上傳的紀錄，紀錄內容有上傳資料的時間，還有上傳的裝置，如果用的是Yun的Linux系統，裝置會顯示PythonSDK，如果沒有任何上傳紀錄，代表你並沒有成功連線到Temboo網站，趕快看看Yun是不是有上網成功喔。

有沒有遇過Temboo傳過這樣的錯誤呢?也不知道為什麼?

這樣的問題除了在Dropbox之外也很容易發生，Temboo提供的一個功能是特別需要注意的，那就是oAuth服務，oAuth所做的是允許認證這項功能

1、允許用戶讓第三方應用存取該用戶在某一網站上儲存的私密的資源

2、無需將使用者名稱和密碼提供給第三方應用

這在ArduinoYun中非常重要，因為Yun很容易社群網站(比如g…

This is a simple example on how to run some code on the Arduino side of the Arduino Yún on specific events fired through the Twitter Streaming API

i.e. when a tweet containing a specific #hashtag is twitted, Arduino blinks an LED

I love this experiment because it's near real time and it gives a lot of possibilities, and it's very easy to set up

Requirements

An Arduino Yún (obviously) with an external SD card (required for hosting the Python libraries you'll need)

A twitter app you own

The Tweepy library for Python

And, finally... this code

:)

Instructions

"I love instructions, they give me confidence." -- me

In case you haven't done it yet, upgrade your Arduino Yún to the latest version and expand it's disk space using the SD card

Log to your Arduino using ssh

Install a bunch of useful stuff

$ opkg update $ opkg install git $ opkg install python-expat $ opkg install python-openssl $ opkg install python-bzip2

easy_install

$ opkg install distribute

pip

$ easy_install pip

tweepy

$ pip install tweepy

or install it manually cloning it from github

$ git clone https://github.com/tweepy/tweepy.git $ cd tweepy $ python setup.py install

If you don't have one, create your twitter app and get your consumer key and consumer secret. Then, generate an access token and get your access token and access token secret

Create a working folder for all the scripts (i.e. /root/python)

$ mkdir /root/python $ cd /root/python

and, while in the python folder, clone the Twitter Blink example

$ git clone [email protected]:amicojeko/TwitterBlink.git

don't forget to make the kill_processes.sh script executable!

$ chmod +x kill_processes.sh

Then use vi or nano (I personally installed vim) to put your twitter app configuration data into the streaming.py script, and to configure the string to be searched inside the Twitter Stream Maelstrom

$ nano streaming.py

now everything should be ready.

Open the Arduino IDE and load the TwitterBlink.ino script that is in the Arduino folder (you can download it from GitHub )

Configure the script folder (in case you created a folder different from root/python/ in the previuos steps)

You can customize the script for your needings, in it's initial configuration it will blink the LED attached to pin 13 (and the built in LED as well) so it's perfect for testing

Upload the script to Arduino, it should start working as soon as it's uploaded

Have fun!!

cheers!
