A consequence of the massive adoption of Internet of Things technologies across all industries is an increasing need for embedded development skills. Yet, embedded development has historically been a pretty complex domain, and not something that one can add to their skillset overnight.
Luckily, over the last decade, silicon vendors have put a lot of effort into simplifying embedded development, especially for people with little to no experience in the domain. Communities such as Arduino and PlatformIO have also immensely contributed to providing easy-to-use tools and high-level libraries that can hide most of the scary details—yes, assembly, I'm looking at you!—of embedded programming while still allowing for professional applications to be written.
