Tutorial ESP8266 and Node-RED MQTT GPIO (Mosquitto) # 1

To integrate the module ESP8266 with node-red IoT platform has been used MQTT protocol, there are client libraries for esp8266 as MQTT in this case I decided to use the library pubsubclient.

This example will receive Node Red that receives data from the ESP8266 and allow control a LED connected to GPIO 02 from a dashboard created in Node Red Dashboard .
