Node MCU - Building a simple Webserver

NodeMCU supports multiple modes for WiFi setup such as Station , Access Point (AP) and other combinations.The tutorial aims at setting up a station which connects to a local Wifi AP and create a local service in ESP8266 to control GPIO's .

Code

  • We have two lua scripts An init.lua to establish a connect and server.lua to run a local service (TCP Server).
  • To download the script run 
    git clone https://github.com/akshaim/NodeMCU
    or download the scripts from here
  • Open server.lua in ESPlorer and click Save to ESP
  • Open init.lua in ESPlorer , Enter you SSID and Password in the fields.Click save to ESP
  • Reset ESP8266
  • The IP address of the device will be displayed in the serial monitor of ESPlorer.
  • Open your browser and enter the IP address.
  • Click on the buttons to observe the output NodeMCU Server
    • LED 1 refers to an LED connected to D1 via 560 Ohm resistor and LED 2 refers to onboard LED on ESP12E
