resetare millies()

[Vizitator sea]

Salutare,

Incerc sa resetez functia millies la fiecare 60 de secunde, mai exact variabila timer_sec

unsigned long timer_min;
unsigned long timer_sec;
String min_sec;

void setup(){
  Serial.begin(9600);
}
void loop(){  
  timer_min = millis()/1000/60;
  timer_sec = millis()/1000;
  
  if(timer_sec == 60){
    timer_sec = 0;
  }
  
  min_sec = String(timer_min) + "min : " + String(timer_sec) + "sec";

  Serial.println(min_sec);
  delay(1000);
}

am incercat cu acel if, insa dupa ce trece de el variabila timer_sec isi continua numerotarea.

 

Cum as putea ca in variabila min_sec, variabila timer_sec sa fie resetata la fiecare 60 secunde?

 

Multumesc!

Salut,

 

Incearca asa:

timer_min = (millis()/1000)%60;

 

Iar functia millis() nu ai cum s-o resetezi. Ete ce zice la docoment:

Returns the number of milliseconds since the Arduino board began running the current program. This number will overflow (go back to zero), after approximately 50 days.

Colegul de mai sus a raspuns corect dar a gresit numele variabilei, vorbim de timer_sec.

Si atunci loop devine:

unsigned long timer_min;
unsigned long timer_sec;
String min_sec;

void setup(){
  Serial.begin(9600);
}

void loop(){  
  timer_min = millis()/1000/60;
  timer_sec = (millis()/1000)%60;
  
  min_sec = String(timer_min) + "min : " + String(timer_sec) + "sec";

  Serial.println(min_sec);
  delay(1000);
}

Corect! Desi, cred ca si minutele si secundele tre' facute modulo 60 pentru cand o pune si orele. Dar mai bine sa-l lasam sa citeasca un pic ce e cu % asta ...

Multumesc mult de ajutor!
