Hello everybody
Due to the lack of good documentation, I reached here to ask
what is official library Arduino_json, used for ?
is it used to store data and is that data retrievable after the power is cut off?
Any effort is appreciated
Json documents are most often used to pack up data to be transmitted to another device.
Just like variables data is lost when powered down.
If you wish to save data after power down it needs to be stored in EEPROM.
