hi, i'm new arduino, don't mad @ me inexperience:-[ my vision: there 4 rooms , monitor temperature of each room. make windows program gui let me see real time temperature in graphs, store data later compare it, lets say, month month before. in future develop system control thermoheads of floor heating based on temperature in each room. my question - best tools that: build monitoring program on windows open , see temperature in real time, pick date , see temperature of date. also, think, there should kind of "server" store data? suggestions? i have skills of using c++, know "if...", "for..." , "while..." , know how thermistor looks it great challenge build real , useful - not "the led goes on , off, on , off..." i'm waiting comments project , tools need used. quote what best tools that: build monitoring program on windows do realise arduino forum ? you may lucky , answer have thought question b...

TFT LCD

mais qui donc su faire fonctionner un tft lcd 1,8'',2.2'',2.8'' ou 3.5'' avec un arduino uno, voir avec un pro mini les sites et forum sont remplis de question réponses qui ne donnent finalement aucune solution complète et ça ne fonctionne jamais, tout au moins pour moi, mais je ne crois pas être le seul. merci à celui ou ceux qui pourront apporter une solution complète (câblage, librairie, exemple de code) car il ou ils feront le bonheur de la plus grande partie d'entre nous je crois donnez plus de détails sur le lcd et votre code.

Controler arduino via le web

bonjour, je débute sur arduino. j'aurais voulu savoir comment procéder pour contrôler un arduino via une appli web, en gros un site web qui enverrai des ordres un arduino (par exemple éteindre/allumer led pin 7) existe t'il un framework ? c'est passionnant en tout cas merci d'avance pour les réponses bonjour un site web est principalement constitué d'un logiciel (serveur web) tournant sur un appareil connecté à un réseau, et conçu pour recevoir des requêtes et envoyer des réponses. les utilisateurs disposent d'un client (un navigateur web ou une application spécifique) qui envoie les premières et reçoit les secondes. le lien entre le serveur et l'arduino doit être choisi en fonction des circonstances. généralement, on fait tourner le serveur web directement sur l'arduino, lequel peut alors traiter les requêtes, en extraire les ordres, commander directement les périphériques concernés, puis retourner à l'envoyeur une inf...
