This tutorial will explain how to use both the PubNub Arduino SDK and PubNub MQTT gateway to send and receive data from a NodeMCU 1. We can program NodeMCU (ESP8266) in several ways. That means that when you are using the MQTT server itself you can connect, because it's all the same computer. Even though my first example only showed one, it is straight forward to get the Arduino PubSubClient library to subscribe to Multiple MQTT topics. IO configuration was a bit tricker, I didn't really want to deal with having the MQTT button query the state of the switch and issues an "ON" or "OFF" command, I just wanted it to "TOGGLE" the switch, regardless of its current state. Sending one byte of data over MQTT is incredibly inefficient. A web-controlled smiling snowball based on the Arduino MKR1000 controlled via WiFi using MQTT, Shitr.
