It works very well for 4 displays as you can see in this video.. ... et si toto==1 est vrai alors la boucle n'est réalisé qu'une fois puisqu'a la fin de la première boucle on se retrouve avec le i=i+1 ET le i++ de la boucle ce qui donne un i égal a 2. Le langage "arduino" est très proche du C et comme tout langage de programmation, il y a des règles de codage à respecter. On achève ensuite le circuit en reliant la masse de la carte Arduino (GND) à la cathode de la LED avec un fil. sathopper Guest; IF with AND and OR fuctions. The use of the arduino would be to process the raw data of the temperature sensor and relay the temperature to the PID. "The Arduino has a single core, it can't do multi threading." In the case of the loop() function in the Arduino environment it does ⦠Jhjh Guest; how to increment and decrement ?
