  ChatGPT is a chatbot that uses a large-scale neural network model called GPT to generate natural language responses. GPT stands for Generative Pre-trained Transformer, and it is a type of model that can learn from a huge amount of text data and produce coherent and diverse texts on various topics. ChatGPT is based on the idea that natural language can be modeled as a sequence of tokens, such as words or characters, and that a neural network can learn to predict the next token given the previous ones. This way, the model can generate texts by sampling tokens one by one, following the probabilities learned from the data. ChatGPT is trained on a large corpus of web texts, such as news articles, blogs, social media posts, books, and more. The model learns to capture the patterns and styles of different types of texts, as well as the common sense knowledge and facts embedded in them. ChatGPT can also adapt to different contexts and domains by using a special token at the beginning of ...

  Hello👋 and welcome to my blog! Today I'm going to talk about git and GitHub, two amazing tools for developers and collaborators. If you're new to these concepts, don't worry; I'll explain everything simply and enthusiastically.  Let's get started!😁 Git  is a version control system that lets you track changes in your code and collaborate with others. It allows you to create different versions of your code, called branches, and merge them together when they are ready. Git also helps you resolve conflicts when multiple people are working on the same file. GitHub  is a platform that hosts your git repositories online. A repository is a collection of files and folders that make up your project. GitHub also provides many features that enhance your git workflow, such as: RED BOX: ❤️ - User_name/repository_name WHITE BOX: 🤍 - the repository is in Public mode (Private mode - only seen by admin/user only) BLUE BOX: 💙 -  Issues:  These are tasks or problems that...

If you are interested in pursuing a career in technology, you might be wondering whether to focus on software or hardware. Both fields have their own advantages and disadvantages, and both are constantly evolving and changing. In this blog post, we will compare software and hardware in terms of their definitions, skills, salaries, and future prospects. Software is the set of instructions or programs that tell a computer or a device what to do. The software can be divided into different categories, such as operating systems, applications, games, web development, data science, artificial intelligence, etc. Software developers use various programming languages, tools, and frameworks to create, test, and maintain software. Hardware is the physical components or devices that make up a computer or a system. Hardware can include processors, memory, storage, graphics cards, keyboards, monitors, printers, etc. Hardware engineers design, develop, test, and troubleshoot hardware components and sy...

   What is Robotics? Robotics is an interdisciplinary field of science and engineering that deals with the creation and use of machines that can perform tasks normally done by humans. Robotics is a fascinating and rapidly evolving domain that has applications in various industries, such as manufacturing, healthcare, agriculture, entertainment, education, and more. In this blog post, we will explore some of the basic concepts and definitions of robotics, such as what a robot is, how robots work, what are the different types of robots, and what are some of the current and future challenges and opportunities in robotics. What is a robot? A robot is a programmable machine that can sense, actuate, and interact with its environment to achieve a specific goal. A robot typically consists of three main components: a mechanical structure that provides mobility and manipulation capabilities, an electrical system that powers and controls the robot, and a computer system that processes inf...

How does home automation work? Home automation is a network of hardware, communication, and electronic interfaces that work to integrate everyday devices with one another via the Internet. Each device has sensors and is connected through Wi-Fi, so you can manage them from your smartphone or tablet whether you’re at home, or miles away. This allows you to turn on the lights, lock the front door, or even turn down the heat, no matter where you are. What are the benefits of home automation? The purpose of a home automation system is to streamline how your home functions. Consider some of these benefits: Remote access: Control your home from mobile devices, including your laptop, tablet, or smartphone. Comfort: Use home automation to make your home a more comfortable, livable space. Preprogram your thermostat with your preferred settings so that your home is always at a comfortable temperature, set up smart speakers to play music when you get home from work, or adjust your lights to soften...

A smart system made by using Node MCU dev board. What is Node MCU? 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.  Both the firmware and prototyping board designs are open source. Requirments Node MCU 4 channel relay toggle switch * 4 Hi-links (220v ac to 5v dc) Circuit Diagram Program #ifdef ENABLE_DEBUG         #define DEBUG_ESP_PORT Serial         #define NODEBUG_WEBSOCKETS         #define NDEBUG #endif #include <Arduino.h> #include <ESP8266WiFi.h> #include "SinricPro.h" #include "SinricProSwitch.h" #include <map> #define WIFI_SSID         "your wifi name"     #define WIFI_PASS         "your wifi pass" #define APP_KEY...

 About Gas Sensor The MQ series of gas sensors use a small heater inside with an electrochemical sensor. They are sensitive to a range of gasses and are used indoors at room temperature. The output is an analog signal and can be read with an analog input of the Arduino. The MQ-2 Gas Sensor module is useful for gas leakage detection in homes and industries. It can detect LPG, i-butane, propane, methane, alcohol, hydrogen, and smoke. Some modules have a built-in variable resistor to adjust the sensitivity of the sensor. Note:  The sensor becomes very hot after a while, don't touch it! Required  Arduino UNO Breadboard MQ-2 Gas sensor module Red, Green led 5mm 220 Ohm Buzzer The connections are pretty easy: The MQ-5 sensor Pin-> Wiring to Arduino Uno A0-> Analog pins D0-> none GND-> GND VCC-> 5V other components Pin-> Wiring to Arduino Uno D13-> +ve of buzzer GND-> -ve of buzzer D12-> anode of red light D11-> anode of green light GND-> cathode...

About the LM35 The LM35 is an inexpensive, precision Centigrade temperature sensor made by  Texas Instruments . It provides an output voltage that is linearly proportional to the Centigrade temperature and is, therefore, very easy to use with the Arduino. The sensor does not require any external calibration or trimming to provide accuracies of ±0.5°C at room temperature and ±1°C over the −50°C to +155°C temperature range. One of the downsides of the sensor is that it requires a negative bias voltage to read negative temperatures. So if that is needed for your project, I recommend using the DS18B20 or TMP36 instead. The TMP36 by Analog Devices is very similar to the LM35 and can read temperatures from -40°C to 125°C without any external components Note that the sensor operates on a voltage range of 4 to 30 V and that the output voltage is independent of the supply voltage. The LM35 is part of a series of analog temperature sensors sold by Texas Instruments. Other members of the seri...
