Salut, oui je sais, le code correspondant à l'horloge n'est pas dans le code que j'ai inscrit, c' est pour ca.
Voila mon code actuel :
#define DHTPIN 3 // sonde dht (t/rh)
#define DHTTYPE DHT22 //#define DHTTYPE DHT11 (capteur DHT11)
#include <OneWire.h> //capteur t
#include <LiquidCrystal.h> //lcd
#include <DHT.h> //capteur dht
#include "RTClib.h"
#include <Wire.h>
DHT dht(DHTPIN, DHTTYPE);
RTC_DS1307 RTC;
float h = 0;
float t = 0;
OneWire ds(4); //capteur t
LiquidCrystal lcd(5, 6, 7, 8, 9, 10, 11);
int backLight = 12; // pin 13 will control the backlight
void setup(void) {
Serial.begin(9600); //capteur t
dht.begin(); //capteur dht
pinMode(backLight, OUTPUT);
digitalWrite(backLight, HIGH); // turn backlight on.
lcd.begin(20,4);
Wire.begin();
RTC.begin();
if (! RTC.isrunning()) {
Serial.println("RTC is NOT running!");
// following line sets the RTC to the date & time this sketch was compiled
//RTC.adjust(DateTime(__DATE__, __TIME__));
}
}
void loop(void) {
DateTime now = RTC.now();

Pour l'instant je n'arrive pas à comprendre pourquoi les secondes se rafraichissent toutes les 4 secondes.
Et comment passer au niveaux des chiffres de 1 à 01 par exemple 01/01/2013 et pas 1/1/2013
