ESP8266 Control Servo Node-RED MQTT (Mosquitto) IoT
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.

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
