Internet of Things & Other Hot Technology Academic Guides and Resources

As academic leaders work to engage students in the key technology areas for businesses, industries,  and entrepreneurs/startups,  academic leaders (like the rest of us) are challenged with keeping up with technology changes in a race without a finish line  There is a crown jewel to assist in these efforts and due to it’s value I have focusing the entire update around this one key resource(s):  IBM Academic Initiative Educator Guides.

These guides are available to academic leaders as part of the IBM Academic Initiative Program.   The IBM Academic Initiative is the program for students and faculty at accredited institutions to get access to IBM resources at no charge for use in teaching/learning and for non-commercial research.   The topics include cognitive computing, internet of things, cyber security, Bluemix cloud plus eight other topics.  The content in the educator guides is similar to the approach for this monthly update:  industry resources with summaries to drive discussion and dialogue around that topic with students.   Additional industry resources are highlighted for faculty and students to get hands on experience along with more assets for students to continue their learning and grow their expertise with studies, Redbooks, white papers, communities and other professional resources to enable them to maintain and grow their expertise as a life long learner.

Typically I reference one educator guide based on the topic for the month.   In recent discussions, educator guides have been the main topic of meetings and calls regardless if the meeting/call was measured in minutes or days.  The below is a summary of all the educator guides with a drill down into the Watson Internet of Things Educator Guide.  Let’s begin…..

Internet of Things on IBM Bluemix

In the initial stage of the Internet, millions of people got connected and trillions of dollars of economic value was created through various new services. In the next stage of the Internet, billions of Things will get connected and in some estimates, there will be 212B connected devices by 2020. With this, we will have unprecedented knowledge about our physical world. This knowledge will offer us the opportunity to create new services that will make our businesses and economies far more efficient and deliver new and enhanced user experiences. Opportunities for value creation are even higher.

A new set of skills is needed to leverage this opportunity. This involves the building of facilities for connecting a large number of devices, designing software to handle huge volumes of data, the creation of a toolset to analyze this data to gain new insights, and the development of facilities for rapid development of new Internet of Things (IoT) applications.

Prepare your students to build in-demand skills around the Internet of Things using IBM’s Platform as a Service, IBM® Bluemix™. This guide contains assets you can use in your classroom to build these critical skills.


The material in this guide is primarily for faculty teaching courses related to Software Engineering. This guide provides an introduction to Internet of Things Platform in Bluemix and shares corresponding labs that you can use in your classroom with your students.

Read this guide to learn more and find introductory videos, tutorials, corresponding labs and exercises you can use in your classroom.


IBM Internet of Things Platform on Bluemix provides a framework for easily connecting devices to the Bluemix Cloud environment and manages them. These devices will generate large amounts of data. IBM provides a visual development environment named Node-RED where various devices can be wired together visually, combined with other services on Bluemix, and also with many publicly available APIs to create interesting applications.

Internet of Things developers working in the Bluemix environment can leverage a large number of services in areas such as data management and analytics provided by IBM and third parties in their applications.

IBM IoT Platform provides developers a means to rapidly connect their sensors and devices to the cloud, and rapidly create and deploy their IoT applications.

Refer the IoT Platform overview presentation for additional details.

Step 5: Request Bluemix promocodes for 6 month student/faculty access

  • Email your name, contact, credentials, school, and the purpose for the code to obtain promocodes for faculty and your students. Faculty are encouraged to request promocodes for all their students to speed up processing.
  • Ensure the promocodes are applied before the account expires. If it expires, you cannot apply the code. You could work with Bluemix support team and get it possibly reactivated. But you risk losing your existing work through this process.
  • If you need a subsequent 6 month promocode, then request new codes for extension. Once again, ensure the code is applied before the account expires
  • Each promocode can be applied only once and to only one Bluemix account. It comes with 2GB and a maximum of 10 services restrictions currently. There may be other restrictions that individual services may have. Refer Bluemix for those details.

Exercise 2: IoT Starter app

Estimated time: 1 hour

The IoT Starter app exercise teaches you to use the IoT Platform Starter boilderplate on Bluemix to create your first IoT app. You will learn to register a Simulated device to the IoT Platform and create dashboards to visualize the data from the device in real time. This activity will also give you an opportunity to explore the Node-Red flow editor, which is an visual app-dev IDE.

Exercise 4: Add a new node (Random) in your Bluemix Node-Red environment

Estimated time: 30 minutes

  • Explore all available nodes and decide on your node(s) to add to the Node-Red environment on Bluemix.
  • Go to the git URL of the application. Create git account if not already created.
  • Click on “Edit code”. Edit package.json
  • Add entry for the new node (remember to add a comma if after adding it at the end of the dependencies. No comma for the last node item). i.e. “node-red-node-random”:”0.0.6″
  • Click on the “Git Repository” icon on the left. Add a comment. Commit. Push-All. Build & Deploy. This will redeploy your app. Wait for the app to run.
  • Refresh your node-red and you should see the new node

Exercise 5: Add a delay in the debug output on Node-Red using Trigger function node

Estimated time: 30 minutes

  • On your Node-Red flow editor: Go to the second flow created by the IoT starter app in Exercise 2.
  • Explore the various nodes in the left panel
  • Drag, drop and connect the “trigger” function node into the flow right after the Watson IoT input node that reads “IBM IoT App in”
  • Double click the “trigger” node and make the following changes:
  • Send = From the drop-down menu select “the existing msg.payload”
  • then = wait for 10 seconds
  • then send = From the drop-down menu select “nothing”
  • Click “Done” and “Deploy”
  • Now the debug output gets displayed only once every 10 seconds instead of every second that came with the IoT starter app

Exercise 6: Add a Watson API (Text to Speech) to your existing app

  • On your Node-Red flow editor: Copy the clipboard content, import from clipboard on to the node-red flow. Click Deploy.
  • Go to the {myapp}
  • With the speaker on your laptop on, inject a text from the node-red flow and listent to it spoken out.
  • Modify the previous flow from exercise 3, to incorporate this audio capability by feeding the “safe” and “danger” node output into the “text to speech” node.
  • Your status should now be spoken to you, instead of being displayed on the debug panel

Exercise 7: Add a Watson API (Language Translation) to your existing app

  • On your Bluemix app dashboard: Go to the Connections tab. Add a new connection. Add Watson Language Translation API to your existing IoT app. It will ask to restage. Restage. Wait for the app to start running. Ensure you have the required credentials for this service.
