• Basic Function test:
  • connect USB cable to PC
  • open Arduino IDE
  • Tools -> Port:
    confirm one is selected
  • Tools -> Board
    NodeMCU 1.0 (ESP-12E Module)
    If it's not there, see ESP8266 Node MCU - Setup/Operation to install
  • in IDE:
    File -> Examples -> ESP8266
    select: Blink
  • compiling and uploading and execution should proceed.

• wifi test:
  • Following tutorial in ref. 01:
    • connected two LED's, each with 330 ohm resistors to ground
      from ESP pins labeled D1 (GPIO4)and D2 (GPIO5)
    • copied arduino code from tutorial
      and saved it to: ESPwebServer.txt
    • copied code into sketch, named: ESPwebServer-01.ino
    • when download successful, open serial monitor at 115200
      press RST button on ESP
      printout should show URL of web page created
            eg. 192.168.0.29
      If Serial Monitor output is gibberish:
      check if correct baud rate selected
      reset router
    • open a web browser and enter the URL from the ESP
    • web page should show two buttons, one for each LED connected to the ESP
    • toggling the buttons on the webpage toggles the LED's on the ESP
