Introduction 

The NodeMCU (Node MicroController Unit) is an open-source development board having Lua based firmware that run on the ESP8266 Wi-Fi SoC, developed by Espressif System, and hardware based on the ESP-12 module.

It is a low cost based which is mostly used in the field of IOT.





Description


NodeMCU is an open-source development board that is based on the ESP8266 microcontroller. It is designed for Internet of Things (IoT) applications and can be programmed using the Lua scripting language or the Arduino programming language.

  • NodeMCU includes built-in Wi-Fi connectivity, which allows it to connect to the internet and to other devices.
  • NodeMCU has a built-in microcontroller that can be programmed to perform various tasks such as reading sensor data, controlling actuators, and communicating with other devices.
  • NodeMCU has a variety of input and output pins that can be used to connect to sensors, actuators, and other devices.
  • NodeMCU is compatible with a wide range of development tools and frameworks, including the Arduino IDE and the Lua firmware.
  • NodeMCU is relatively low cost and has a small form factor making it suitable for a wide range of IoT projects.
  • NodeMCU can be used in a variety of applications such as home automation, sensor networks, and wireless control systems.
  • NodeMCU is also compatible with a number of other IoT platforms such as Blynk, Adafruit IO, and Thingspeak, which allows for easy data collection and visualization.
  • NodeMCU can be powered by a USB cable or a lithium-ion battery, making it portable and easy to use in a variety of environments.
  • NodeMCU is open-source which means it can be modified, customized and used freely.

It's worth noting that NodeMCU is constantly evolving and changing, so the information I've provided is accurate at the time of my knowledge cut-off and there may be newer developments or advancements in the field

  What is Computer? A computer is an electronic device that manipulates information or data. It has the ability to store, retrieve, and process data. Nowadays, a computer can be used to type documents, send email, play games, and browse the Web. It can also be used to edit or create spreadsheets, presentations, and even videos. Functions of Computer:  A Computer can perform the following set of functions:  1. Accept data   2. Store data   3. Process data as desired  4. Retrieve the stored data as and when required  5. Print the result in desired format. Components of Computer: It mainly has two major components:  i. Hardware         1. Input Device         2. Output Device         3. Storage Device    ii. Software          1. System Software         2. Application Software         3. Utilities Softwa...

                      First Generation Computer   First Generation: 1946-1959 is the period of first-generation computer.  J.P. Eckert and J.W.  Mauchy invented the first successful electronic computer called ENIAC, ENIAC stands for “Electronic Numeric Integrated and Calculator”.  Few Examples are:   ENIAC   EDVAC  UNIVAC   IBM-701   IBM-650 Advantages:  1. It made use of vacuum tubes which are the only electronic component available during those days.  2. These computers could calculate in milliseconds. Disadvantages: 1. These were very big in size, weight was about 30 tones.  2. These computers were based on vacuum tubes. 3. These computers were very costly.  4. It could store only a small amount of information due to the presence of magnetic drums. 5. As the invention of first-generation computers involves vacuum tubes, so another ...

Z-WAVE

-
  Z-Wave is a wireless communication protocol that is used for home automation and other low-power, low-data-rate applications. It is based on the ITU-T G.9959 standard and uses the 908.42 MHz frequency band. Z-Wave devices can be used to create a mesh network, in which each device can act as a relay for other devices, allowing for a larger coverage area. Z-Wave devices are typically used in home automation, industrial automation, healthcare, and other applications that require low-power, low-cost, and low-data-rate wireless communication. Z-Wave devices can be powered by batteries and have a longer battery life compared to other wireless technologies. Z-Wave networks can be secured using AES-128 encryption. Z-Wave Alliance is a group of companies that develop and promote Z-Wave technology. Z-Wave devices can be connected to other networks using Z-Wave-to-IP gateways, which allow for remote control and monitoring of Z-Wave devices over the Internet. Z-Wave devices can be integrated...
