Video Tutorials

In a previously-run studio, a series of video tutorials were produced that walked through some example IoTa flows as deployed on the server.

The studios have ended, but here's the list of videos that you might nonetheless find useful – just note that these tutorials point to specific servers and names related to that studio, but the steps on how to work on these flows are essentially the same.

Paging through a large dataset

Datasets tend to return large numbers of rows. This tutorial uses some paging techniques to iterate over your data in such a way that it becomes compatible with our IoTa+Photon recipe.

Using CSV files in your data flows

How to import data sources that only provide CSV formats from the Internet.

Using an edited CSV file as a data source

This tutorial demonstrates how you might use an existing CSV file that you have edited as a data source for your project. Note that this will not be applicable if you have not been given access to upload to the studio servers.

Free FTP Software you can use for file transfers:

Mac: Transmit
PC: WinSCP

Using Twitter

How to connect to Twitter.

NOTE: Twitter just made updated changes to their API which effectively means that the light blue Twitter node you see in this video has been disabled, until an updated version is available. Refer to the portion that talks about the dark blue Twitter-stream node instead, if you wish to work with Twitter in IoTa.

NOTE: In addition, Twitter has introduced far more stringent application checks for developer accounts. The official documentation suggests creating new apps by linking your Twitter handles to an approved developer account set up by your tutor.

Sentiment Analysis

Once you know how to retrieve tweets from Twitter, performing sentiment analysis on these text message may give us a bit more insight into the messages. You can also perform sentiment analysis on larger bodies of text (it will likely be more accurate, too).
