Sure, this works fine.

1) Plug NodeMCU into PC, install driver if needed. Remember what serial port it represents
2) Put NodeMCU into firmware upload mode: Hold RST and FLASH buttons, Release RST, Release FLASH.
3) Configure Arduino (Tools menu) to NodeMCU board, your serial port, flash size, etc.
4) Upload sketch.

Now your NodeMCU is flashed with your Arduino sketch. To make it a NodeMCU again, just get the NodeMCU flasher, which will come with the latest NodeMCU firmware bundled in it.

It works also for ESP8266 serial WIFI Witty cloud MINI nodemcu, which is a little cute square board with a RGB led and a photoresistor built in.

- Wed Feb 24, 2016 8:27 pm #41836 quick question about the driver you are talking about. If I want to use NodeMCU as arduino. What should I do to deal with the driver thing?
