Do you want to develop skills to prototype mobile-enabled products using state-of-the-art technologies? In this course you will build a hardware and software development environment to guide your journey through the Internet of Things specialization courses. We will use the DragonBoard™ 410c single board computer (SBC). This is the first in a series of courses where you will learn both the theory and get the hands-on development practice needed to prototype Internet of Things products. This course is suitable for a broad range of learners. This course is for you if: • You want to develop hands-on experience with mobile technologies and the Internet • You want to pivot your career towards the design and development of Internet of Things enabled products • You are an entrepreneur, innovator or member of a DIY community Learning Goals: After completing this course, you will be able to: 1. Configure at least one integrated development environment (IDE) for developing software. 2. Make use of git, adb and fastboot to flash multiple OS and repair bricked boards. 3. Install Android 5.1 (Lollipop) and Linux based on Ubuntu. 4. Create, compile and run a Hello World program. 5. Describe the DragonBoard™ 410c peripherals, I/O expansion capabilities, Compute (CPU and Graphics) capabilities, and Connectivity capabilities.

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.

Welcome back everyone.

In this section, we're gonna be going over different and

various Git commands that you use to utilize Git.

>> So first, before you create, or essentially what you

want to do to start your Git repository is the git init command.

And this will just initialize a git repository and create a dot

git file that will essentially be the key to being able to use Git on your computer.

>> However, if you don't want to create your own repository initially,

you want to just copy someone else's from GitHub or Bitbucket or

from some other repository, the git clone command actually helps you achieve that.

You just type in git clone and

type in the URL to wherever that repository is located.

>> And next we have the git add command and the git rm or git remove.

And what these commands do is they essentially add files or

remove files that are being tracked with your git.

So for example, if Ara has or if Ara created a new file,

let's say awesome.java, and he wants to add that to the local repository,

you'd have to do git add awesome.java, and then if he wants to

remove that file from being tracked with Git, the he can do git rm to remove it.

>> Next is the git commit command, which is actually the bread and butter for

Git and basically any type of version control system.

After you've added all your files to be tracked, or

removed any files from tracking,

using a git commit command basically creates a snapshot of that moment in time.

And basically, that's really good for if you do subsequent commits,

it's gonna go ahead and keep different versions over time.

>> And also, with commits, you're able to leave messages to a lot of your teammates,

or your friends, or whoever, to see what kind of changes you've made, as well.

>> Exactly.

And then the last two commands are the git push and the git pull command,

which basically go hand in hand.

So we are talking about GitHub and Bitbucket, so how exactly do we push code

from our computer to those online repositories and vice versa,

git push pushes code from your computer to the online repository, whereas git pull

actually pulls any changes that were made from the repository onto your computer.

So in that way you're able to keep not only your code updated but

also the repositories.

>> And do note that there are other Git commands that are available,

however we found that these are the most common ones that are used.

For full documentation, you can probably go the Git website and

kind of check them out, as well.

>> Exactly.

So now what we're gonna do is we're gonna, in the next section,

we're gonna be going over basically the life cycle of Git.

And as you know, it's kind of in the same order that these commands are,

more or less.

So I'll go ahead and see you there.
