 Nous voulons que notre noeud "inject" sorte le texte 'Hello World' toutes les 3 secondes. Configurez les options comme indiqué ci-dessous:

+Le noeud "Inject" est très polyvalent et vous pouvez planifier régulièrement des injections à différents moments de la journée (une fonctionnalité vraiment pratique).
-The inject node is very versatile and you can schedule it to inject at various times of day which is really useful. I use it to automate fetching the weather to my twitter account just before I wake to go to work.
+Dans notre cas, cela permet d'aller rechercher les informations de météorologique et d'envoyer l'information sur un compte twitter.

-I have explained quite a few fundamentals during this stage of the tutorial but the exact same process can be used with the other nodes. You simply drag and drop them on to the canvas, wire them together, change their settings and deploy.
+Nous avons expliqué quelques éléments fondamentaux dans cette partie du tutoriel mais ces fonctionnalités sont valable pour n'importe quel autre noeud. Vous les déposez sur la feuille, les branchez ensembles, modifiez leur paramétrage et déployer votre solution.
-The next stage of the tutorial will move in to making more nodes available and ensuring the environment is set up to run them.There are nodes such as the twitter node that require some further dependencies to be setup other than the ones discussed so far.
+La prochaine partie de ce tutoriel s'attardera sur l'ajout de nouveaux types de noeud et vous assurez qu'ils fonctionneront dans votre environnement.
