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
|
|
