IoT, web apps, and connected devices are all becoming increasingly popular. But, the market still resembles a wild west apothecary, and no single IoT ecosystem or architecture seems to be the one bottle of snake oil we’ll all end up using. As such, we hackers are keen to build our own devices, instead of risking being locked into an IoT system that could become obsolete at any time. But, building an IoT device and interface takes a wide range of skills, and those who are lacking skill in the dark art of programming might have trouble creating a control app for their shiny new connected-thing.
Enter Involt, which is a framework for building hardware control interfaces using HTML and CSS. The framework is built on Node-Webkit, which means the conventions should be familiar to those with a bit of web development background. Hardware interactions (on Arduinos) are handled with simple CSS classes. For example, a button might contain a CSS class which changes an Arduino pin from high to low.
While Involt isn’t the only framework to simplify hardware interaction (it’s not even the only Node.js based method), the simplicity is definitely laudable. For those who are just getting started with these sorts of devices, Involt can absolutely make the process faster and less painful. And, even for those who are experienced in this arena, the speed and efficiency of prototyping with Involt is sure to be useful.
