Is the .ino
file an alternative from a main.cpp
file?
If yes, then could someone mind explaining the structure of the .ino
file in main.cpp
and its relationship?

The Arduino uses the gcc compiler. That compiler wants a normal main
function of course. Arduino has put a layer on top of that with setup
and loop
.
The hidden main
function for basic Arduino boards is in main.cpp (click on it to see it).
You see that init
is called, and setup
and loop
and a few other things.
To learn how to use setup
and loop
, you can try a few examples. They are in the menu of the Arduino IDE and they are also online.
The .ino files are all combined together and presented to the compiler as a single .cpp file to compile. The Arduino libraries are compiled from source as well, and everything is linked into a binary.
When you know how to use setup
and loop
, try the Blink Without Delay example. It can be used to run different software timers and do all kind of tasks and keep everything running smooth.
