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,
|
|
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.
|
|
|
|
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
