Weather station example for e-radionica.com Inkplate 6
For this example you will need only USB cable and Inkplate 6.
Select "Inkplate 6(ESP32)" from Tools -> Board menu.
Don't have "Inkplate 6(ESP32)" option? Follow our tutorial and add it:
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,
e.g. Metaweather public weather API
IMPORTANT:
Make sure to change your desired city, timezone and wifi credentials below
Also have ArduinoJSON installed in your Arduino libraries
