Un programme sur Arduino est au moins constituée de 2 parties obligatoires :
/* Blink Turns an LED on for one second, then off for one second, repeatedly. */ void setup() { // initialize digital pin LED_BUILTIN as an output. pinMode(LED_BUILTIN, OUTPUT); }
loop
(void) appelée qui est appellé régulièrement aprèes l'initialisation par la fonction setup
.// the loop function runs over and over again forever void loop() { digitalWrite(LED_BUILTIN, HIGH); // turn the LED on (HIGH is the voltage level) delay(1000); // wait for a second digitalWrite(LED_BUILTIN, LOW); // turn the LED off by making the voltage LOW delay(1000); // wait for a second }
