- Understand the basics of Development Boards based on ESP8266, like NodeMCU
- Make simple projects based on ESP8266 based Development boards
- Understand how to run MQTT Client on the NodeMCU and connect to a server on the cloud
- Basic knowledge of Electronics, Processors and C language
This course is a short introduction to the NodeMCU, its various Firmware options and how we program it with the Arduino IDE. This is suitable for a beginner level student, who wishes to get some introduction on how to work with such boards, like Arduino or NodeMCU that use the ESP8266 chipset. Small programs are provided that do some basic tasks, like blinking LEDs on the NodeMCU board.
There is also an example of how to use IBM's Message Queue Telemtry Transport protocol with NodeMCU as an IOT Device, and acting as a MQTT Client. In the example, the NodeMCU sends Telemetry data to a MQTT Server/Broker, and a publisher, that can be an android app, subscribes to the "Topic" of this message, and is able to receive messages sent by the NodeMCU to the Server/Broker. This is slightly more complex example of running a MQTT Client on the board, that pushes MQTT messages to ant MQTT server on the cloud.

We are using ESP8266 12E on a NodeMCU Development Board. Information on ModeMCU can be found at http://www.nodemcu.com/index_en.html.
NodeMCU is an ESP8266 on a custom dev board with a firmware written in MicroPython that incorporates GPIO, PWM, IIC, 1-Wire and ADC functions, along with a Lua environment and built-in libraries to use Wifi, MQTT, telnet, etc.
The schematic for NodeMCU can be found at https://raw.githubusercontent.com/nodemcu/nodemcu-devkit/master/Documents/NODEMCU_DEVKIT_SCH.png.
