Familiarization with ESP8266 NODEMCU
Brief about ESP8266 NODEMCU:
The NodeMCU (Node MicroController Unit) is an open-source software and hardware
development environment built around an inexpensive System-on-a-Chip (SoC) called the
ESP8266. The ESP8266, designed and manufactured by Espressif Systems, contains the crucial
elements of a computer: CPU, RAM, networking (WiFi), and even a modern operating system
and SDK. That makes it an excellent choice for Internet of Things (IoT) projects of all kinds.
The NodeMCU is available in various package styles. Common to all the designs is the base
ESP8266 core. Designs based on the architecture have maintained the standard 30-pin layout.
Some designs use the more common narrow (0.9″) footprint, while others use a wide (1.1″)
footprint – an important consideration to be aware of.
The most common models of the NodeMCU are the Amica (based on the standard narrow pin-
spacing) and the LoLin which has the wider pin spacing and larger board. The open-source
design of the base ESP8266 enables the market to design new variants of the NodeMCU
continually.
KNOWING THE ESP8266 NODEMCU – Become familiar with the ESP8266 NODEMCU
board, and identify all the pins as described in the data-sheet.
PROGRAMMING USING ARDUINO IDE – Install the required plugin in the Arduino IDE so
that you can program your NODEMCU using Arduino IDE.

GETTING STARTED – write a program to blink a LED connected with pin D5.
CONNECT WITH WIFI – write a program to connect with your personal hotspot and print the
IP address on the serial monitor.
DISPLAY TIME FROM INTERNET – After connecting with WiFi, get time from internet using
NTP clock project and display on serial monitor.
