 Le premier argument du constructeur {{fname|QTRSensorsAnalog}} est un tableur de broche analogique (0 – 7) alors que le premier argument du constructeur {{fname|QTRSensorsRC}} est un tableau de broche digital (0 – 19).
-Note that analog inputs 0 – 5 can be used as digital pins 14 – 19. For more details, see [[Pololu-Senseur-QTR-Utiliser|utilisation et notes]].
+Note: les broches analogiques 0 – 5 peuvent être utilisée comme les broches digitales de 14 à 19. Voyez la page [[Pololu-Senseur-QTR-Utiliser|utilisation et notes]] pour plus de détails.
-The only other difference you might experience is in the time it takes to read the sensor values. The QTR-xRC sensors can all be read in parallel, but each requires the timing of a pulse that might take as long as 3 ms (you can specify how long the library should time this pulse before timing out and declaring the result full black). The QTR-xA sensors use the analog-to-digital converter (ADC) and hence must be read sequentially. Additionally, the analog results are produced by internally averaging a number of samples for each sensor (you can specify the number of samples to average) to decrease the effect of noise on the results.
+La seule différence que vous pourriez noter, c'est le temsp nécessaire pour lire les valeurs du senseur. Les senseur QTR-xRC sont tous lus en parallèle mais nécessite le temps de traitement d'une impulsion qui peut prendre jusqu'à 3ms (vous pouvez spécifier à la bibliothèque le temps max -''timeout''- de cette impulsion avant avant de retourner un résultat comme "noir"). Les senseur QTR-xA utilise le convertisseur analogique-vers-digital (ADC) et doit donc lire les entrée séquentiellement. De surcroît, le résultat analogique est produit par un calcul de moyenne sur plusieurs échantillons pour chacun des senseurs (il est possible de préciser le nombre d'échantillons). L'utilisation d'une moyenne permet d'atténuer l'effet du bruit.
-Several example sketches are available to help you get started. To view the example sketches, open the Arduino IDE and navigate to:
+La bibliothèque contient différents croquis pour vous aider à démarrer. Pour voir les croquis d'exemples, ouvrez Arduino IDE et naviguez dans le menu:
-'''File > Examples > QTRSensors'''
+'''Fichier > Exemples > QTRSensors'''
-As a first step, we recommend using '''QTRARawValuesExample''' (for QTR-xA sensors) or '''QTRRCRawValuesExample''' (for the QTR-xRC sensors). These examples will simply print the raw readings from the sensors to the serial monitor, using 9600 baud. Once that is working, you might want to try one of the more advanced examples, '''QTRAExample''' or '''QTRRCExample''', which incorporate calibration and also estimate the position of a line.
+Comme première étape, nous recommandons d'utiliser l'exemple '''QTR''x''RawValuesExemple''':

-You should now be able to use these libraries in your sketches by selecting '''Sketch > Import Library > QTRSensors''' from your Arduino IDE (or simply type {{fname|#include <QTRSensors.h>}} at the top of your sketch).

-Once this is done, you can create a '''QTRSensorsAnalog''' object for your QTR-xA sensors and a '''QTRSensorsRC''' object for your QTR-xRC sensors:

-// create an object for three QTR-xA sensors on analog inputs 0, 2, and 6
+// Créer un objet pour 3 senseurs QTR-xA sur les
 QTRSensorsAnalog qtra((unsigned char[]) {0, 2, 6}, 3);

+// Créer un objet pour senseurs QTR-xRC sur les

-This library takes care of the differences between the QTR-xA and QTR-xRC sensors internally, providing you with a common interface to both sensors. The only external difference is in the constructors, as you can see in the code sample above. The first argument to the QTRSensorsAnalog constructor is an array of analog input pins (0 – 7) while the first argument to the QTRSensorsRC constructor is an array of digital pins (0 – 19). Note that analog inputs 0 – 5 can be used as digital pins 14 – 19. For more details, see [[Pololu-Senseur-QTR-Utiliser|utilisation et notes]].
+Cette bibliothèque prend en charge -en interne- les différences entre les senseurs QTR-xA et QTR-xRC. Grâce à la bibliothèque vous disposez d'une interface commune pour les deux types de senseur. Comme vous pouvez le constater dans le code d'exemple ci-dessus, la seule différence se trouve au niveau du constructeur.
