RE: Flight Simulator 101 or back to college - part 14: Programming Arduino like an adult! Kill the loop()!

Chris, in Arduino, everything is a class. Each Arduino library is a c++ class.

The part about loop(), main() and macros is wrong. The Arduino libraries implement main(). And in that main(), they first call setup() once, then continuously loop(). .

https://github.com/arduino/ArduinoCore-avr/blob/master/cores/arduino/main.cpp

int main(void)
{
 init();

 initVariant();

#if defined(USBCON)
 USBDevice.attach();
#endif
 
 setup();
 
 for (;;) {
 loop();
 if (serialEventRun) serialEventRun();
 }
 
 return 0;
}
