#include

Description

L'instruction #include est utilisée pour insérer des librairies externes dans votre programme. Ceci donne accès au programmeur à une large groupe de librairies standard en langage C (groupes de fonctions pré-fabriquées), et également bien sûr des librairies écrites spécialement pour Arduino.

La page de la référence principale pour les librairies AVR en langage C (AVR est la référence des microcontrôleurs Atmel utilisé avec les cartes Arduino) est ici.

Noter que l'instruction #include (qui est une instruction destinée au pré-compilateur), de même qu'avec #define, n'a pas besoin de point-virgule en fin de ligne. Le compilateur donnera un message d'erreur énigmatique si vous en ajoutez une.

Exemple

Exemple 1

This example includes the Servo library so that its functions may be used to control a Servo motor.

#include <Servo.h> Servo myservo; // create servo object to control a servo void setup() { myservo.attach(9); // attaches the servo on pin 9 to the servo object } void loop() { for (int pos = 0; pos <= 180; pos += 1) { // goes from 0 degrees to 180 degrees // in steps of 1 degree myservo.write(pos); // tell servo to go to position in variable 'pos' delay(15); // waits 15ms for the servo to reach the position } for (int pos = 180; pos >= 0; pos -= 1) { // goes from 180 degrees to 0 degrees myservo.write(pos); // tell servo to go to position in variable 'pos' delay(15); // waits 15ms for the servo to reach the position } }

Exemple 2

This example includes the pitches.h file, which is placed in the same directory with the sketch (the sketch's folder).

/* * This example code is in the public domain * Tutorial page: https://arduinogetstarted.com/tutorials/arduino-piezo-buzzer */ #include "pitches.h" int melody[] = { NOTE_C4, NOTE_G3, NOTE_G3, NOTE_A3, NOTE_G3, 0, NOTE_B3, NOTE_C4 }; int noteDurations[] = { 4, 8, 8, 4, 4, 4, 4, 4 }; void setup() { for (int thisNote = 0; thisNote < 8; thisNote++) { int noteDuration = 1000 / noteDurations[thisNote]; tone(8, melody[thisNote], noteDuration); int pauseBetweenNotes = noteDuration * 1.30; delay(pauseBetweenNotes); noTone(8); } } void loop() { }
