Buonasera a tutto il forum.
Dopo aver risolto un enorme problema di sequenzialita' di.apertura e chiusura elettrovalvole azionate a solenoidi, si presenta immediatamente un nuovo problema....nooooooooo.....
La necessità è quella di inserire il nuovo codice per l'apertura sequenziale delle valvole all'interno di un.switch case, in quanto questa è solo una possibile selezione in quanto le valvole possono essere in automatico, problema risolto, o in manuale accese o spente.
Il codice con millis dopo.tanto tempo e prove adesso funziona perfettamente, ma quando lo inserisco in un switch case, le aperture non rispettano più la precedente sequenza che in uno sketch per i fatti suoi invece funziona perfettamente.
Quale potrebbe essere il problema?
Vi ringrazio per qualsiasi aiuto o suggerimento.
ciao Danpis,
inserisci lo sketch...ed indica la parte che non funziona
Grazie ORSO per la risposta, ti allego di seguito lo sketch funzionante

a questo sketch se aggiungo la parte seguente nel loop, si modificano completamente tutti i tempi di HIGH e LOW che altrimenti sarebbero corretti e funzionanti:
if(Serial.available())
{
sel=Serial.read();
}
switch(sel) {
case '1' : [
automatic();
break;
}
ovviamente la variabile sel è stata dichiarata precedentemente.
Spero che tu riesca ad aiutarmi,
ti ringrazio per il tempo che mi stai dedicando
Ringrazio tutti per l’aiuto,
ho comunque risolto, il problema era dato dal non aver dichiarato le variabili current millis a zero nelle dichiarazione iniziali.
Senza la dichiarazione a zero, la variabile veniva creata al momento in cui la parte di codice veniva eseguita e questo creava i millisecondi di ritardo che modificavano i valori dei ritardi, in modo completamente casuale, questo mi ha fatto pensare a differenze di calcolo che potevano essere date dal problema che ho risolto su indicato.
Grazie a tutti
Se potesse essere utile a qualcuno, di seguito lo sketch riguardante l’apertura e chiusura sequenziale di elettrovalvole o qualsiasi carico da gestire con relè e ritardo con millis.
Nelllo sketch è integrata la prima parte di uno switch case, a me utile per la gestione di alcuni parametri da remoto, ovviamente questa parte è da terminare.
