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.

Step 4: Images

According to the tests performed, the MQTT protocol is very fast,

allowing communication between Node-RED and ESP8266 to be almost in real time.

From certain protocols we have tested, we consider and recommend implementing the MQTT for your IoT projects
