I was about to write my own JSON serializer for my Feather project in C++. Went on GitHub -> Your lib -> Your blog -> Your channel -> this video. Subbed!

To bad you do not have other videos. You have the ability to explain things in a very clear way.

This one is the truly holy grail : snprintf_P(s, sizeof(s), PSTR("%s is %i years old"), name, age); it made my code work again. Thanks!
