Preface
This book describes the role that JavaScript plays in embedded devices. Driven by Arduino and Raspberry Pi, there is an ongoing democratization of hardware development processes. New boards and software toolchains make hardware development more accessible, the same way full stack JavaScript’s usability made programming easier to approach.
Inspired by open feedback and worldwide collaboration, there are evolving communities on the Web where people join hands to build weather stations, robots, or spectrometers (for a nice overview of this trend, see the entries for the 2015 Hackaday Prize).
Compared to those “hobby” projects, professional hardware development often comes with high costs of special computer-aided design (CAD) software products or additional toolchains. This is very different from web development, where the free and open source tools hobbyists use to build are often the same tools used by professionals. In open source software, the lines frequently blur between the work of professional and hobbyist: thousands of examples can be found on GitHub, where many software developers (often joined by “hobbyists”) build solutions for business or private needs.
The Arduino and Raspberry Pi ecosystems already heavily depend on open source projects hosted on GitHub. But for building embedded systems, GitHub is not a complete solution because it is not built for collaboration on hardware, and change detection between revisions of a hardware board can be very messy. (There ...
