Make sure you are using Arduino IDE version 1.7 or higher.Step 1: Adding ESP8266 URL to Arduino IDE Board Manger NodeMCU or ESP8266 board (for testing only).The ESP8266 community has written all the code which abstracts away the nitty gritty of the SDK into much easier to use functions. All weve had to do is install the Arduino environment, add ESP8266 to the Boards Manager, and then select our board after we plug it in. Its popularity has been growing among the hardware community thanks to its nice features and stability, to the point that it can be easily programmed using your Arduino IDE. Arduino is the fastest way to get up and running with the ESP8266. The NodeMCU ESP8266 is a low-cost WiFi module built by Espressif Systems. ![]() NodeMCU board is not available by default.
