What is NodeMCU in IOT?

The NodeMCU (Node MicroController Unit) is an open source software and hardware development environment that is built around a very inexpensive System-on-a-Chip (SoC) called the ESP8266.

Can we use NodeMCU for commercial use?

It is clearly intended for hobbyist and learning purposed and not optimised to be used commercially.

Why NodeMCU is widely used in IoT projects?

NodeMCU is an open source and LUA programming language based firmware developed for ESP8266 wifi chip. ESP8266 has very low cost and high features which makes it an ideal module for Internet Of Things (IoT). It can be used in any application that require it to connect a device to local network or internet.

What can ESP8266 do?

The ESP8266 module enables microcontrollers to connect to 2.4 GHz Wi-Fi, using IEEE 802.11 bgn. It can be used with ESP-AT firmware to provide Wi-Fi connectivity to external host MCUs, or it can be used as a self-sufficient MCU by running an RTOS-based SDK.

What is Arduino IoT cloud?

Arduino IoT Cloud is an application that helps makers build connected objects in a quick, easy and secure way. You can connect multiple devices to each other and allow them to exchange real-time data. You can also monitor them from anywhere using a simple user interface.

What is NodeMCU in simple words?

NodeMCU is an open source firmware for which open source prototyping board designs are available. The name “NodeMCU” combines “node” and “MCU” (micro-controller unit). The term “NodeMCU” strictly speaking refers to the firmware rather than the associated development kits.

How many pins are there in NodeMCU?

17 GPIO pins
GPIO Pins. ESP8266 NodeMCU has 17 GPIO pins which can be assigned to various functions such as I2C, I2S, UART, PWM, IR Remote Control, LED Light and Button programmatically. Each digital enabled GPIO can be configured to internal pull-up or pull-down, or set to high impedance.

Is ESP32 used professionally?

> There are literally no commercial products that use ESP32 (or its older brother ESP8266) besides some chinese cheap toys on Amazon. There are lots of commerical IoT devices that use the ESP chips (Shelly, Sonoff, Tuya e.g.). The final product is better than almost any “professional” IoT device.

Can we use ESP8266 in production?

ESP8266 is just for learning . It should never be used in industries. It doesn’t even meet the industrial standards. The chip is very sensitive to fluctuating voltage levels or noises.

How to use NodeMCU IoT project?

>Compile and upload your code. >Connect the power pin of the led to digital pin 7 of the NodeMCU. >Connect the GND pin to GND on the NodeMCU. So you guys can see the photos and video and the NodeMCU IoT project is working perfectly fine.

What is nodenodemcu used for?

NodeMCU is an inexpensive and powerful development chip (cost between 3–12$) that have good I/O capabilities with GPIO pins and can also communicate with other devices using WiFi. This makes it ideal for our use to prototype in small-scale IoT applications. Here is a picture of pin mapping:

What is the NodeMCU dev kit?

“NodeMCU is open source platform, it’s hardware design is open for edit/modify/build. NodeMCU Dev Kit/board consist of ESP8266 wifi enabled chip.The ESP8266 is a low-cost Wi-Fi chip developed by Espressif Systems with TCP/IP protocol. It can be used for a wide variety of IoT applications.

What are the different types of nodemcu boards?

There have been many different ESP modules over the years, each with their own advantages and drawbacks. There have been just two types of NodeMCU boards, however: versions 0.9 and 1.0. The 0.9 version is blue and comes loaded with the ESP-12 chip, while the 1.0 is black, and comes with the ESP-12E (which stands for ‘enhanced’).
