 ## Motivation
-I write a lot of code for Arduino, especially libraries. The Arduino IDE is not suited for more complex projects and I tried several alternatives. The old and dysfunctional Arduino CDT extension for eclipse somehow stalled (even if it was promising), Sloeber could be an option but the maintainer is disillusioned and the project is more or less dead. Platform IO IDE's license is very [restrictive](https://community.platformio.org/t/what-part-of-platformio-is-open-source-licenced/1447/2).

+* Sloeber could be an option but the maintainer is disillusioned and the project is more or less dead. Furthermore Eclipse is pretty heavy and less accessible to beginners

-Then remains vscode-arduino. It seems that it isn't completely dead - but almost. Most of the core functionality seems to work (I used it a few days now). But the biggest show stopper is the bad IntelliSense support.

 ## Beer Money :beers:
 You can chip in some beer money to keep me motivated - this is really appreciated.
