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 13const 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; digitalWrite(GRN, HIGH); delay(540000); digitalWrite(GRN, LOW); digitalWrite(YEL, HIGH); delay(180000); digitalWrite(YEL, LOW); digitalWrite(RED, HIGH); delay(120000); digitalWrite(RED, LOW); delay(1000); digitalWrite(RED, HIGH); delay(1000); digitalWrite(RED, LOW); delay(1000); digitalWrite(RED, HIGH); delay(1000); digitalWrite(RED, LOW); delay(1000); digitalWrite(RED, HIGH); delay(1000); digitalWrite(RED, LOW); delay(1000); digitalWrite(RED, HIGH); delay(1000); digitalWrite(RED, LOW); delay(1000); digitalWrite(RED, HIGH); delay(1000); digitalWrite(RED, LOW); delay(1000); digitalWrite(RED, HIGH); delay(1000); digitalWrite(RED, LOW); delay(1000); digitalWrite(RED, HIGH); delay(1000); digitalWrite(RED, LOW); delay(1000); digitalWrite(RED, HIGH); delay(1000); digitalWrite(RED, LOW); delay(1000); digitalWrite(RED, HIGH); delay(1000); digitalWrite(RED, LOW); delay(1000); digitalWrite(RED, HIGH); delay(1000); digitalWrite(RED, LOW); delay(1000); digitalWrite(RED, HIGH); delay(1000); digitalWrite(RED, LOW); delay(1000); digitalWrite(RED, HIGH); delay(1000); digitalWrite(RED, LOW); delay(1000); digitalWrite(RED, HIGH); delay(1000); digitalWrite(RED, LOW); delay(1000); digitalWrite(RED, HIGH); delay(1000); digitalWrite(RED, LOW); delay(1000); digitalWrite(RED, HIGH); delay(1000); digitalWrite(RED, LOW); delay(1000); digitalWrite(RED, HIGH); delay(1000); digitalWrite(RED, LOW); delay(1000); digitalWrite(RED, HIGH); delay(1000); digitalWrite(RED, LOW); delay(1000); digitalWrite(RED, HIGH); delay(1000); digitalWrite(RED, LOW); delay(1000); digitalWrite(RED, HIGH); delay(1000); digitalWrite(RED, LOW); delay(1000); digitalWrite(RED, HIGH); delay(1000); digitalWrite(RED, LOW); delay(1000); digitalWrite(RED, HIGH); delay(1000); digitalWrite(RED, LOW); delay(1000); digitalWrite(RED, HIGH); delay(1000); digitalWrite(RED, LOW); delay(1000); digitalWrite(RED, HIGH); delay(1000); digitalWrite(RED, LOW); delay(1000); digitalWrite(RED, HIGH); delay(1000); digitalWrite(RED, LOW); delay(1000); digitalWrite(RED, HIGH); delay(1000); digitalWrite(RED, LOW); delay(1000); digitalWrite(RED, HIGH); delay(1000); digitalWrite(RED, LOW); delay(1000); digitalWrite(RED, HIGH); delay(1000); digitalWrite(RED, LOW); delay(1000); digitalWrite(RED, HIGH); delay(1000); digitalWrite(RED, LOW); delay(1000); digitalWrite(RED, HIGH); delay(1000); digitalWrite(RED, LOW); delay(1000); digitalWrite(RED, HIGH); delay(1000); digitalWrite(RED, LOW); tone (10, 750); delay(200); noTone(10); delay(100); tone (10, 1000) ; delay(200); noTone(10); delay(1000); tone (10, 750); delay(200); noTone(10); delay(100); tone (10, 1000) ; delay(200); noTone(10); 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 solutionmerci d'avance!

Bonjour/Bonsoir, Qui pour vérifier un programme Arduino? C'est pour lundi svp Explications: Lorsque le bouton est pressé, le compte a rebours se lance, la LED verte s'allume (pendant 9 minutes), puis la jaune (pendant 3 minutes) et enfin la rouge qui clignote (pendant les 3 dernières minute). Au bout de ces 15 minutes, le buzzer sonne. Le problème c'est le compte à rebours: il s'affiche sur le LCD mais ne tourne pas. Sinon tout le reste fonctionne. Bon courage et merci d'avance! 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; digitalWrite(GRN, HIGH); delay(540000); digitalWrite(GRN, LOW); digitalWrite(YEL, HIGH); delay(180000); digitalWrite(YEL, LOW); digitalWrite(RED, HIGH); delay(1000); digitalWrite(RED, LOW); delay(1000); digitalWrite(RED, HIGH); delay(1000); digitalWrite(RED, LOW); delay(180000); tone (10, 750); delay(200); noTone(10); delay(100); tone (10, 1000) ; delay(200); noTone(10); delay(1000); } else{ digitalWrite(RED, LOW); digitalWrite(YEL, LOW); digitalWrite(GRN, LOW); noTone(10); } }

Bonjour Je voudrais savoir si le fait de saler un plat est une transformation chimique, physique ou est-ce un mélange
