Remember Arduino and Nodemcu Pins are different, but the programming style is exactly the same. All the functions that you have been using with Arduino boards can also be used with the Nodemcu ESP8266. But, first you will need to install the Nodemcu ESP8266 Board before you can start programming using the Arduino IDE, I will explain this in a minute. The best thing about the Nodemcu ESP8266 Wifi module is that it can be programmed using the Arduino IDE.
In this article, I will explain each and every detail so that you can easily start with this amazing WiFi Module called the Nodemcu ESP8266. I am writing this article for the beginners having no prior knowledge of the Nodemcu ESP8266. So, this is the reason I am writing this article to answer all your questions. I am asked the same question again and again “How to install the Nodemcu ESP8266 in the Arduino IDE”, “How to use set up the library for the Blynk?”, “How to write our first program for the Nodemcu ESP8266 using the Arduino IDE?”, “Nodemcu ESP8266 Pinout and technical specification?”, and so many other questions. I have been using Nodemcu ESP8266 for quite a long time in different IoT based projects. Nodemcu ESP8266 Arduino IDE- This is a very basic getting started tutorial on the Nodemcu ESP8266 WiFi Module developed by the Espressif Systems.
