What is NodeMcu8266

NodeMcu8266 is a development board which built into esp8266 wifi module . NodeMcu8266 is an Open Source Hardware device that has mainly application in making IOT devices.
It can be program using Arduino IDE and the coding structure remains similar to that of Arduino but ArduinoIDE do not come with pre-installed ESP supported boards on it, so one need to add/import the board attachments to the IDE before programming it and is very simple to do.
ESP series boards are not initially developed for Arduino IDE compatibility, therefore in Arduino IDE each pin on NodeMCU corresponds to different GPIO pin for IDE. Here, is the pin mapping of NodeMCU GPIO pins. In Coding you can directly write digital pins of NodeMCu as D1,D2,D3… or corresponding GPIO pin no.
