As promised, I updated the book Mastering ArduinoJson so that it stays relevant.
If you already purchased the book, you can download the new version for free (if not, what are you waiting for?).
- The book is in-sync with ArduinoJson 5.13
- It has a new front cover
- I fixed many embarrassing typos
- I added a survey at the end
As a reminder, version 5.13 changed the way ArduinoJson duplicates strings (see complete article).
