https://e-radionica.com/en/blog/add-inkplate-6-to-arduino-ide/
This example will show you how you can use Inkplate 6 to display API data,
in this example Metaweather public weather API which provide weather info.
As a result, you get a functional weather station which shows today's
forecast and 3 days forecast on your Inkplate display.
e.g. Metaweather public weather API
IMPORTANT:
Make sure you have changed your desired city, timezone and WiFi credentials below.
You will also need to install ArduinoJSON library.
Download from here: https://github.com/bblanchon/ArduinoJson
Make sure to change your desired city, timezone and wifi credentials below
Also have ArduinoJSON installed in your Arduino libraries
