Course Highlights - Node MCU Basics and Installation on Arduino IDE, Digital and Analog Sensor Interfacing to Node MCU, Sensor data upload to Thingspeak Server, MQTT Protocol and Sensor Data upload to MQTT Broker, Node Red and creating Apps on Node Red and Data upload from Node MCU to the apps. This Course can be understood by anyone without any prior knowledge on Node MCU or Embedded systems or IoT. Everything is explained from the basics including the hardware interfacing and the software coding.This course starts with the basics of Node MCU, Installing Arduino IDE and libraries required for Node MCU. The Digital and Analog sensors are Interfaced to Node MCU and the working of the sensors and the required code for that is explained. Sensors like DHT and Ultrasonic sensors are also Interfaced to NodeMCU. The sensor data is uploaded onto the Thingspeak Server using HTTP GET and POST requests. MQTT Protocol is explained in detail with practical use cases and Implemented on Node MCU. Installation of PubSubClient library is shown on the Arduino IDE and then used to upload the sensor data to the MQTT Broker. Node red is taken up as the next topic and the course is ended with uploading data from NodeMCU to Node Red.End to end Applications are shown with hardware interfacing on Node MCU and coding on Arduino IDE. Applications related to data upload from DHT sensors andUltrasonic sensors are shown and Home automation application which controls the appliances connected to the relay is also shown in three different types. Controlling devices from the MQTT Box application, from Android App and from Node Red app is also shown.
