Arduino MQTT Tutorial - Coding & Live Demo using SIM900

Blog post for code & files : https://www.valetron.com/arduino-mqtt... In this video we will see how we can write simple Arduino code to interact with a MQTT broker through a TCP connection created by SIM900 GSM GPRS module. You can also use this same code along with SIM800 or SIM808 modules which support the same AT commands for TCP/IP.
