We need to add NodeMcu ESP 12 to our Arduino IDE. Open up your IDE then go to “File -> Preferences” or simply hit “Ctrl + comma”
Paste http://arduino.esp8266.com/stable/package_esp8266com_index.json in additional board manager URLs.
Go to “Tools -> Board -> Boards Manager” search and install esp8266
Close and restart your Arduino IDE
Plug in your NodeMcu to your computer.
Go to Tools -> Port and select the COM Port of your NodeMCU. If you are not sure what port your NodeMcu is plugged in, go to Device Manager -> Ports (COM & LPT)
Now select NodeMcu 1.0 (ESP-12E Module) by clicking Tools -> Board. Scroll down until you find it.
Download Arduino ESP8266 Filesystem Uploader (direct link) Unpack the tool in your sketchbook directory (the path will look like <sketchbook directory>/tools/ESP8266FS/tool/esp8266fs.jar).
