How to upgrade from ArduinoJson 6 to 7

In this video, we learn about how to upgrade the code written for ArduinoJson 6 to use the new version 7. ArduinoJson 7 comes with a straightforward API and no breaking changes, so the code you wrote for version 6 should still compile with no errors. However, it will produce many warnings if the code is still tied to the deprecated API. This video is composed of two parts: the first details the changes you must apply, and the second demonstrates how to upgrade two example programs. Join us to learn how to easily upgrade your code and enjoy the new API of ArduinoJson 7.
