For some reason I have been experiencing similar problems obtaining information on Instrumentino and Controllino software.
After much frustration, I have only determined that Instrumentino and Controllino are complementary software packages that allow a user to easily interact with the hardware on an Arduino board. This interaction may include reading data from sensors or resistors attached to the input of an Arduino, or changing the output values of an Arduino by altering the parameters of variables inherent within the sketch it is running.
More specifically, Instrumentino is design software that allows you to build a custom GUI, specific to the needs of your project. Once completed, this program resides and runs on a local computer. Consequently, the local computer 'hosts' the GUI, providing the user with a graphical environment in which to make or read the changes to the Arduino previously described.
Controllino, on the otherhand, is the second half of the equation. It is the control software that allows the hardware attached to your Arduino to communicate directly with the GUI software. It does this, over a serial connection established between the two entities, the host computer and the Arduino board. This software is uploaded to your Arduino as a sketch and as such, runs on the Arduino concurrent to the GUI program on the host computer. It acts much like the driver software in your computer's operating system, allowing software and hardware to interface seamlessly.
While I am uncertain how to download and use Instrumentino, I believe Controllino has to be downloaded as a library to your Arduino IDE. Like other libraries not native to the IDE software, the library is initially saved on your computer and then imported to the IDE separately. After being imported, the Controllino library will be available from within the IDE. The features of the library can be accessed from within a sketch by referencing the appropriate include statement. IE - #include controllino
Unfortunately, most of the websites claiming to be devoted to Instrumentino and Controllino are vague, confusing or contradictory. They either redirect the individual to a respository on GitHub or offer convoluted lessons on how GitHub is suppose to work. They consistently fail to provide any clear instruction on how to download, install or use the software, nor do they provide any real life examples of either of these programs in action.
I find this very disturbing. This software could prove of great benefit to the Arduino community, and yet it is being allowed to die a quick death because of the Helen Hunt Syndrome...As they say, if you want further information on the subject, just go to Helen Hunt for it. What is needed is a dedicated web portal. A place where people can readily download the software. A place that not only offers instruction on installation and use, but also allows the user to watch video of the software being implemented. Perhaps a dedicated channel on YouTube.
I would very much like to help correct this problem, but unfortunately do not know enough about the software to commit myself to such a project. If however, there are others in the Arduino community willing to educate me, I would be more than happy to contribute my time to such an endeavor. Not only would it help me complete, document and share my own project, but I am sure that it would greatly enhance the projects of others.
