Visual Programming Guide
An overview of available graphical programming software tools. From supported languages to overviews of tools for Arduino and Raspberry Pi.
It wasn’t many years ago that using a computer meant literally learning a new language.
Innovations like the graphical user interface exposed basic elements like the filesystem to a wider audience, and the Internet has become increasingly democratized as user-friendly tools like WordPress, Youtube and Soundcloud allow anyone to create, publish and distribute content without writing a line of code. Today an explosion of accessible prototyping kits is making it possible for amateurs and hobbyists to sink their teeth into the growing Internet of Things by cobbling together connected computing projects.
But when it comes to making that hardware do your bidding, most tinkerers will still encounter a “language barrier”. Even the most user-friendly development boards need to be programmed; and even the simplest programming languages still look like alphabet soup to the uninitiated.
Fortunately, some developers have started to step in and provide user-friendly, visual programming tools. These platforms abstract away the functions, variables and idiosyncratic syntax rules of the underlying code and give users a simple drag-and-drop interface for building apps out of discrete chunks of logic (“When this happens, do that”) and widgets that can apply settings tailored to any specific piece of hardware.
Here’s a roundup of visual programming platforms that have some application to the Internet of Things—either because they’re tailor-made for programming sensors and embedded computers, or because they’re general-purpose platforms for programming in the languages that are compatible with those devices.

"Drag and drop the Internet of Things”
The NETLab Toolkit, or NTK, displays its prebuilt chunks of code as widgets — little boxes full of input fields, sliders, toggles, and other on-screen controls. Users choose widgets suited to the task at hand, set the parameters for each one, and connect them together in a logical sequence to create a program. NTK programs are compatible with the original Arduino and similar Linux-based embedded computing hardware. Philip van Allen, a professor at the Art Center College of Design, created NTK as a teaching tool and continues to expand the platform by releasing new widgets.

“A professional tool to build robust IoT applications”
Reactive Blocks is distributed as a plug-in for the Eclipse integrated development environment. Its preprogrammed code blocks are designed around large-scale Internet of Things applications, such as sensor networks, home automation and industrial monitoring. Reactive Blocks also touts itself as an ideal solution for “gateway” applications — programs, running on hardware like wireless routers, that process incoming data from local sensors and devices. These gateway apps can then make decisions without having to pass all of the raw data on to a remote cloud server, a concept known as “edge” or “fog” computing.
