Overview
ESP8266 WiFi internet development module. Uses Prolific USB to Serial Converter.

Just a quick note, ESPlorer seems to be having trouble uploading .lua files in the latest version. For some reason when it writes the file it uses the writeline function, which seems to corrupt the data. If anyone has information I can pass on about this, let me know please, Tech@QKits.com its at the bottom of every web page.


Using LuaLoader is a good way around the issue, and no nagging Donate button. Its small and simple.


print ("Hello World")  save this line to a file Hello.lua, upload it to the NODEMCU,    dofile("Hello.lua")     it should print



Hello World


Turn ON the  On Board LED   gpio.write(0,gpio.LOW)  save it as ON.lua, upload dofile("ON.lua") the LED should turn ON


Turn OFF the  On Board LED   gpio.write(0,gpio.HIGH)  save it as OFF.lua, upload dofile("OFF.lua") the LED should turn OFF.


This will let you know that you are on track and things are working.

This is an economical solution for IoT and WiFi-capable devices. The ESP8266 was developed as a Serial to Wi-Fi adapter and the firmware implemented an intertrepeter for AT commands.

The ESP8266 is so popular becaue of the 2×4, 0.1" pitch connector that can easily be wired to a USB to Serial adapter. The connector gives access to the pins used for serial communication (RX and TX, 4 control pins, GPIO0, GPIO2, CH_PD and RST (reset), along with VCC and GND).
