⚠️ ⚠️ ⚠️ ARTIK Cloud has been depcreciated by Samsung ⚠️ ⚠️ ⚠️ Here we create an ESP8266/32 based device that emulates a RGB LED light using NeoPixels, which connects to ATRIK cloud. ARTIK cloud connects to smart home assistants like Google Home, Amazon Alexa, etc. Connecting to Samsung ARTIK Cloud https://my.artik.cloud/ GitHub: debsahu/ARTIKCloud An application made for ESP8266 to comunicate with ARTIK Cloud Connects to ARTIK Cloud via MQTT SSL port 8883 ARTIK Cloud is connected to all assistant platforms, integration is seamless Compiles on ESP8266-arduino core v2....

Demonstration on ESP8266 & ESP32 using SSL/TLSv1.2 two-way handshake with secured mosquitto broker. SSL is preferred way of encryption of communication between devices over the internet. Here we secure a mosquitto MQTT broker and connect to it via ESP8266 & ESP32 that do a two-way handshake.
