GitHub repository to start with Arduino with several modules and devices

Hi everyone!

I have created a GitHub repository I want to share that contains different modules and devices examples I worked with. I will add more as soon as I have spare time:

They are basic examples, to learn how to connect and work with each module, and add more functionality or combine them.
One of them is the official example, but full documented, with voltage info and so on, in the same "ino" to avoid looking for this info on the Internet.
All of them have one picture to see the device.

I have chosen MIT license to allow everybody use, modify, share, etc.

As most of repositories, it is open for contributions. Please, I appreciate if all examples follow same structure.
