This is a short, easy, beginner friendly tutorial on how to get setup with the NodeMCU. I tell you a little bit about the NodeMCU, then I show you how to very quickly set it up. I show you how to set up the Arduino Software and I go through how to get the blink sketch working – In 7 minutes! The NodeMCU is basically an ESP8266 mounted on a break out board.
