Where to get the ArduinoJSON dependency

[Tech1k]

The newest update for ESP boards (2.6.3) requires ArduinoJSON library that's needed to parse the data coming from the Duino-Coin /getPool API to automatically connect to the least loaded node.

If you do not have the ArduinoJSON library installed, you will get an error during compilation.

To install it, we recommend using the Arduino library manager:

Open your Arduino IDE > Sketch > Attach libraries > Manage libraries > Type ArduinoJson and install the newest version (6.18.13).

After doing this you should have no problems related to JSON with compiling the code.

Alternatively you can install the library manually (won't auto-update):

Download the https://github.com/bblanchon/ArduinoJson library and unzip in your Arduino libraries folder (see https://www.arduino.cc/reference/en/libraries/)

Thank you for the details, it is worked, the only thing that did not work is to download the zip file, I download ad update the library but did not works, so I choose to update the library directly from tools, I go to (tools), and from the list I choose (Manage Libraries), from the windows I write (JSON), the list opened, and I find 2 Jason, I install Arduino Jason from the list and after that, I manage to update my ESP8266 and worked, the picture below as proof

Good evening, I have had problems when compiling the program, the version I use is the most current and this is what I get

I would be very grateful if you help me.
