What is NodeMCU How to Code LUA Script with a Simple Lines of Code

NodeMCU is an Open Source Firmware Development Board that helps you to build your IOT(Internet of Things) projects with a few LUA Script Lines, NodeMCU it is like Arduino Hardware with a Input Output built in the Board itself, it has also a Wifi built in to connect directly to internet to control your things online using Nodejs Style network API for digital network applications, which facilitates developers to code running on the Board, Greatly speed up your Internet of Things application development process.

The Development Board base on ESP8266 Chip, integrated GPIO(General Purpose Input Output), PWM(Pulse with Modulation),IIC(Interconnected Integrated Circuit), 1-Wire and ADC all in one board to power up your development board in fastest way combined with the NodeMCU Firmware.

Development Board Features:

• OPEN SOURCE Development Board
• USB to TTL built in “Plug & Play”
• 10x GPIO(General Purpose Input Output)
• Built In Wireless Network(Wifi) to Communicate true out the Internet
