ESP32 Tutorials

[anteph]

Hi,

I've been writing some tutorials about the ESP32 at my blog, which are available in the link bellow. I'm covering some basic topics, such as how to connect to a WiFi network or how to connect to MQTT broker, and some more advanced ones, such as using FreeRTOS in the Arduino IDE environment.

https://techtutorialsx.com/category/esp32/

Hope it helps others.

Best regards,
Nuno Santos
