MQQT protokoli orqali qurilmadan Wemos D1 mini platasiga ulangan analog datchik ma’lumotlarini olish uchun Arduinoning ichki “ArduinoMqttClient.h” bibliotekasi va Mosquitto brokeridan foydalanamiz. Biblioteka Arduino IDE ga o’rnatilganidan so’ng, “\u041f\u0440\u0438\u043c\u0435\u0440\u044b” menyusida “ArduinoMqttClient<\/strong>” bo’limi paydo bo’ladi. Biz ushbu bo’limdagi “WiFiSimpleSender<\/strong>” (nashrchi rolida), “WiFiSimpleReceiver<\/strong>” (obunachi rolida) hamda ularning umumlashgan ko’rinishi – “WiFiEcho<\/strong>” (ham nashrchi ham obunachi rolida) namunaviy sketchlarining o’zimizga moslashtirilgan ko’rinishlaridan foydalanamiz (barcha sketchlarda – Mosquitto<\/strong> serveri broker vazifasini bajaradi). Lekin, yuqoridagi sketchlarga kichik o’zgartirishlar kiritamiz: sketchdagi mikrokontrollerdan WiFi tarmoqqa ulanish qismini alohida funksiya tarzida ifodalangan, o’zimizga tanish bo’lgan ko’rinishga keltiramiz, shuningdek, yuboriladigan ma’lumot sifatida termistor ko’rsatkichlaridan foydalanamiz.<\/p>\n

Yana bir (4-) misolda esa, Wemos D1 mini platasiga raqamli DHT11 termodatchigini ulaymiz va uning ko’rsatkichlarini brokerga yuboramiz, shuningdek, yuboriladigan xabar yordamida platadagi ichki svetodiodni boshqaramiz. Lekin biblioteka sifatida “knolleary” muallifligidagi universal bibliotekadan foydalanamiz. Har doimgidek, yangi tushunchalar izohlab boriladi.

1-misol.<\/em> Wemos D1 mini platasiga ulangan NTC-termorezistor (termistor) ko’rsatkichini aniqlab, MQTT brokerga yuboramiz. Ya’ni, Arduino qurilmasi – nashrchi rolini bajaradi. Obunachi sifatida esa, “MQQT Dashboard client<\/a>“<\/strong> nomli tayyor mobil ilovadan foydalanamiz (shunga o’xshash boshqa ilovalardan ham foydalanish mumkin). Ilovani Google Play Marketdan yuklab olamiz va unga MQQT-broker sozlamalarini kiritamiz:<\/p>\n
