			== Overview ==

			The '''NodeMCU''' is a compact and low-cost development board based on the '''ESP8266''' Wi-Fi chip. It is widely used in IoT (Internet of Things) projects to connect devices to the internet. The board has built-in '''Wi-Fi''', a '''USB port''', and can be programmed easily using the '''Arduino IDE'''.

			It is ideal for beginners who want to build smart devices such as Wi-Fi switches, wireless sensors, or simple automation systems.

			=== NodeMCU vs ESP32 – Basic Difference ===
			* '''NodeMCU''' is best for simple, single-task Wi-Fi projects.
			* '''ESP32''' is more advanced with more '''GPIO pins''', '''Bluetooth''', and '''faster processing'''.
			* Start with NodeMCU for learning, and upgrade to ESP32 for complex tasks.
