Arduino core for ESP8266 WiFi chip
https://github.com/esp8266/Arduino
ESP8266 Arduino core comes with libraries to communicate over WiFi using TCP and UDP, set up HTTP, mDNS, SSDP, and DNS servers, do OTA updates, use a file system in flash memory, and work with SD cards, servos, SPI and I2C peripherals.
Start Arduino and open the Preferences window.
Enter https://arduino.esp8266.com/stable/package_esp8266com_index.json into the Additional Board Manager URLs field. You can add multiple URLs.
Open Boards Manager from Tools > Board menu and install esp8266 platform (and don't forget to select your ESP8266 board from Tools > Board menu after installation).
Documentation: https://arduino-esp8266.readthedocs.io/
Then go to the board manager and install esp8266:
Select your board:
Tools > Board > NodeMCU 1.0 (ESP - 12E Module)
To upload the sketch code to the NodeMCU board, first select port on which you connected the board.
