Syllabus

  • Introduction
    • Welcome to the Internet of Things! Before diving into this course give us a chance to let you know what it is all about! We will walk you through a module by module outline that will give you highlights on the interesting aspects of the course.
  • Terminology/Cheat Sheet (Beginner)
    • In this course, you will see a lot of new words and acronyms you might not be familiar with. If you feel comfortable with your knowledge of tech terminology, feel free to skip these lessons since they will not affect the overall integrity of the course. If you see something that you want to know a little more about, feel free to watch the video to gain insight on some basic concepts. We do expect you to know the majority of this material before going into the next module, we would recommend going through the lessons as a quick brush up.
  • Board Bring up
    • The new and exciting DragonBoard™ 410c is now available! In this module you will get introduced to the new all-in-one board, get an overview of all its amazing features and find out how you can get one yourself. We will then walk you through the registration process, and how to get your board started up for the first time! By the end of this module you will know enough about the DragonBoard™ 410c to begin using it for the fun projects that are to come later in this course and in the rest of the courses in the Internet of Things specialization.
  • Setting up your Developing Environment
    • In order to easily communicate with your DragonBoard™ 410c it is essential to set up a developing environment. In this lesson we will talk about Android Studio as our preferred IDE (Integrated Development Environment), we will show you how and where to download it as well as walk you through the installation process on both Mac/Linux and Windows. As an Android developer you will need a variety of tools, these tools come bundled with the Android Studio download and are referred to as the SDK (Software Developer Kit). This lesson will cover accessing the SDK and utilizing the various tools it has to offer. ADB (Android Debug Bridge) and Fastboot are among the tools we will be using most throughout this course. It is with these tools that you will be able to access your board at all levels and make crucial changes needed for development.
  • Changing your Operating System
    • The DragonBoard™ 410c is capable of running a variety of different operating systems, that being said you are free to chose the operating system that you find is best fit for you. Now, we understand that there is a diverse user base for this board and would like to cover as much as possible in this lesson so everyone can enjoy it! Whether you are a Windows user or a Mac user, or prefer Android over Ubuntu, there is a video or two here for you! In this lesson we will help you choose an operating system to best fit for your needs, we will then cover the download, flashing and installation process for all currently available operating systems. Because of the diverse nature of this board we will teach you multiple ways to flash your new operating system and provide a pro's and con's list for the different methods. By the end of this lesson switching between operating system will be easy and exciting for users of all skill levels.
  • Rescuing your Bricked Board
    • No one expects to damage their new DragonBoard™ 410c, but sometimes accidents happen. This module is dedicated to helping you not only prevent these accidents from happening, but also to fixing any problems should your board become damaged in any way. Here we will go over the difference between a soft brick and a hard brick and why they are two things you want to avoid.
  • Creating your First Application
    • Welcome to Module 6! In this module we will be creating your first Android App to port to the DragonBoard™ 410c. This “Network Test” App will give you a teaser for the programmatic feats you will be able to accomplish with the DragonBoard™! You will learn about the different GPS and Location Services available on Android and how to access Bluetooth and Wi-fi Data. This module will briefly go over the importance of the Android Manifest and asking the Users for the proper permissions. Lastly, we’ll spice up our application by playing around with Intents and enabling the application to facilitate the above connectivity and network tests. This may sound like a lot, but don’t worry! We will help you get on your feet and by the end of this module, you’ll have coded a neat little application.
  • Native Development Kit (NDK)
    • In Module 7, will give you a general introduction and brief overview of Android Studio’s Native Development Kit (NDK). The NDK allows us users to program Android applications using C/C++. The NDK utilizes the Java Native Interface (JNI) to facilitate code and interaction between Java and C/C++. This tool was created for users who either have existing C/C++ libraries or plan to use libraries only available in C/C++. Android Studio has a specific build and compilation process catered specifically for NDK Applications that we will explain and cover in this Module. Once we have a better understanding of the NDK, we will create a straightforward “Hello World!” application.
  • CALIT2 Bird Application
    • Who doesn’t love a good game to pass time? In this Module, we will create a more advanced and interactive Android Application / Game! We will be creating our version of FlappyBird--CalliBird or Calit2Bird, as we like to call it. We will cover the basics of the game by defining certain parameters. First, we have what we call our “Actors”. You can think of “Actors” as any part of the game that appears on the screen (the obstacles and the bird). In the game, we also define our own Location system and a Map class that will handle the different movements in the game. Next we define our game processor which is the backbone of the game. Game Processor ensures your score is constantly updated, delegates the movements to the Map class, and detects collisions, to name a few. Lastly, we will cover the importance of interfaces and its application to this Android App. Interfaces will enable us to 1. play CalliBird / Calit2Bird using any form of input we want (using touch, a sensor, a controller, etc.) and 2. render the game in any display we have (a screen, an led block, etc.). There is a lot of freedom with this game so you will be able to spice it up and make it your own!
  • Monitoring your DragonBoard™ 410c
    • Congratulations! You’ve made it to the last module of Course 2! In this Module we will cover a more advanced NDK Application. This application is a bit more challenging than prior applications because it is coded in both Java and C. Regardless of the rigour, we know you’ll be able to accomplish this feat! As for the application, we will be turning our DragonBoard™ 410c into a web server! This web server will detail information regarding the DragonBoard™ 410c’s connectivity, GPIOs, and any other statuses you may want to add. We will pull the information from the DragonBoard™ and encode it in a JSON format using Java, then use C to establish a server connection and send the data out. We will walk you through our code and thought processes so that you can gain a better understanding of how to use the NDK to run Android Applications as well as a taste of what the Internet of Things is all about.

  • Tom
    Course is pointless because they do not tell the prerequisites, neither a hardware list nor is the Dragonboard available, even the price is unknown. I posted those questions in the forums, the Teaching Stuff posted no answer/useless answer. At least a student posted the price of the board. Internet search did not give a result. Normally you are flooded with commercials. What is the purpose of a course, if the hardware is not available, even not in a highly industrialized country? Btw: They have a close relationship with Qualcomm=Dragonboard. Course is a waste of time and temper!
  • Dave
    CON:

    I HATE HATE that they have "student lecturers" - they are not good at it. They fumble through their "script" and act as tho the whole thing is a big joke. This is so annoying I opted to not finish the lectures and just downloaded the various cheat-sheets.

    Often the links to resources are bad or outdated and/or the "how to" android IDE instructions do not actually quite work as indicated and one is left scouring the forums or internet trying to resolve the issues.

    PRO:

    The content is potentially quite good - showing all the steps to build download and debug apps on the Dragonboard - which is an Android board basically like guts of a cell phone minus the phone.
  • Anonymous
    I have finished the first 2 sections out of the specialization. Some of the content is good but the videos are not very well done IMO and nothing has been updated for two years. There is also no support from the teacher or the mentors on the forum. I can not recommend spending money for this course. If you can audit it for free there is some good material but you still have to do a lot of research to get the outdated code repositories and source code to work.
  • Khaya
    The course is amazing, getting to know internet of things. And everything is good. Students must also take these courses to uplift thier knowledge or skill by writing or taking these online courses.
