This time the integration of ESP8266 and the Node-RED platform has been made integrating an actuator in this case a servo controlled by PWM with rotation from 0 to 180 degrees. From an HMI or SCADA Web creator on Node-Red-Dashboard using as base the MQTT Protocol and pubsubclient library converting the ESP8266 into MQTT Client….
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…

In short MQTT is a TCP / IP protocol lightweight messaging, the model is publication – subscriber requires a message broker which is responsible for directing recipients through a topic in common. It is considered to Andrew James Stanford-Clark as the author of this protocol. More information MQTT Wikipedia. Official Website:…
