Bonjour,


je rencontre des difficultés en arduino:

le projet est une minuterie de 15mn sur un écran LCD, j'utilise aussi un bouton poussoir, un buzzer et des LEDs.


tout fonctionne sauf l'affichage du compte à rebours sur l'écran LCD : il reste figé a 15 minutes... Est-ce un problème de code de montage ou les deux?

Voici le code :


#include
#define BUZ 10
#define RED 11
#define YEL 12
#define GRN 13

const int bouton = 9;

const int rs = 2, en = 3, d4 = 4, d5 = 5, d6 = 6, d7 = 7;
LiquidCrystal lcd(rs, en, d4, d5, d6, d7);

long timeInit=0;
int tHour=0;
int tMin=15;
int tSec=00;

int timeToCounter(int h,int m,int s) {
return h*3600+m*60+s;
}

void counterToTime(long cnt) {

tHour=(cnt/3600);
tMin= (cnt%3600)/60;
tSec = ((cnt%3600)%60);
}
void setup() {

pinMode(RED, OUTPUT);
pinMode(YEL, OUTPUT);
pinMode(GRN, OUTPUT);
pinMode(BUZ, OUTPUT);
pinMode(bouton, INPUT);

lcd.begin(16, 2);
analogWrite(8,15);
lcd.print("Il reste :");

timeInit=timeToCounter(tHour,tMin,tSec);
}
void loop() {

int test = digitalRead(bouton);

if(test==LOW) {

counterToTime(timeInit);
lcd.setCursor(0, 1);
lcd.print(tHour);
lcd.print(" h ");
lcd.print(tMin);
lcd.print(" m ");
lcd.print(tSec);
lcd.print(" s");

delay(1000);
timeInit=timeInit-1;

delay(1000);
}
else {

digitalWrite(RED, LOW);
digitalWrite(YEL, LOW);
digitalWrite(GRN, LOW);
noTone(10);
}
}


P.S.: existe-t-il une autre commande pour faire clignoter la led rouge pendant la dernière minute plutôt que d'utiliser :

_

delay(1000); |

digitalWrite(RED, HIGH); |_ x30

delay(1000); |

digitalWrite(RED, LOW); _|


ça serait sympa de partager la solution


merci d'avance!
