Hello everyone, I am a beginner to this platform and have only made 4-5 basic apps. I visit the community regularly and see questions asked about "Arduino" and "ESP32".
I want to know what these actually are and how can I use them with App Inventor (any tutorials or books).
I did some beforehand research on Google and found that ESP32 is basically a PCB( Printed circuit board) but can't understand how it works and what can I do with them.
Any help would be appreciated.
