Ciao a tutti, mi son fatto una piccola funzione di blink per vedere quando il mio loop inizia solo che non succede assolutamente nulla.
Parto dal presupposto che questa funzione l'ho fatta perche' il delay(int millis) di arduino sembra non contare ed aspettare il tempo giusto. Ho messo delay(100060MIN) ma non aspetta 10 minuti prima di proseguire con il loop, cosi' ho voluto provare a vedere mettendo un blink quando riparte il loop per capire se effettivamente rimane in atesa questi 10 minuti.
La funzione di sleep e' questa:
void setup()
{
pinMode(LED_BUILTIN, OUTPUT);
}
void blink(int times)
{
while(times > 0)
{
digitalWrite(LED_BUILTIN, HIGH); // turn the LED on (HIGH is the voltage level)
delay(300); // wait for a second
digitalWrite(LED_BUILTIN, LOW); // turn the LED off by making the voltage LOW
delay(300);
times--;
}
}
void loop
{
blink(10);
}
Costruita cosi' da sola funziona benissimo appena la importo nel mio programma il LED non si accende!
Premetto di non aver provato ad usare altri pin e led perche' volevo far una prova al volo per vedere se funziona. QUalcuno ha idea del perche' non va? Ho pensato che nel setup c'e' qualcosa di strano che blocca l'uso del pin 13 del LED pero' non saprei.
