How Setup Arduino IDE for NodeMCU(ESP8266)

Hi there,

Today I will show you how to install ESP8266 support for the Arduino IDE and at the end you already should be able to flash your code directly from Arduino IDE to your NodeMCU. So let's start!

First of all open the Arduino IDE and go to File > Preference
