Hey readers! I hope you are having a good day. Today, we are learning the basics of another MQ sensor family, the MQ-3. This sensor is designed for the detection of alcoholic gases in the air surrounding it. Gas sensors are widely used in multiple applications, and they provide information to the other components of the circuit. In the air, it can detect the 25-500ppm alcohol gas concentration and is a highly sensitive detector. We are going to study it thoroughly from scratch.
In this article, we are going to start the discussion with the basic introduction of this sensor. We’ll understand its datasheet and will know the basic details about its internal and external structure. After that, we’ll move towards the features, specifications, and best platform to buy these sensors. Then, we’l ...

Generative AI is a remarkable innovation, and the results of its use are captivating. Tools like DALL-E and ChatGPT have rapidly transitioned from research labs into the mainstream. They are widely discussed on social networks, used by both professionals and laypeople, and their outputs – be it texts, images, or code – resemble human creations remarkably.
According to Statista
, the generative AI market will reach $207 billion by 2030. It will show an impressive annual growth rate of 24.4% between 2023 and 2030. Another source, MarketResearch.Biz, expects the size of the generative AI market in software development to hit $169.2 billion by 2032. However, due to the rapid pace of current advancements, it's challenging to predict exact figures; this technology is expanding at breakneck s ...
Hello friends, I hope you all are doing great. In today’s tutorial, we will discuss What is Thermistor. A thermistor is a semiconductor temperature sensing module, its value of the resistance is larger than the conductive substances and less than the insulators. The materials used for the construction of the thermistor defined the value of resistance and temperature of the thermistor. The producers of the thermistor make accurate relationship among temperature and their resistance because it is a very important factor for the users of the thermistor.
Oxides of the metals are used for the creation of the thermistors. During their manufacturing, the ratio of the resistance and temperature is defined accuratly because it is an important factor that d ...
Hello friends, I hope you all are doing great. It's the 8th tutorial in our Raspberry Pi programming course. In the previous lectures, we interfaced LCD 16x2 and Keypad 4x4 with Raspberry Pi 4. In this chapter, we are not going to interface any external module with Pi, instead, we'll create a PWM signal in the raspberry pi using Python. Let's get started:
Components RequiredWe are going to use the below components in today's PWM project:
Raspberry Pi 4.
LED.
A resistor of 330 ohms.
Breadboard.
Jumper wires.Before going forward, let's first understand what is PWM:
What is PWM?
In PWM(Pulse Width Modulation), we simply turn on and off our power supply at regular intervals and thus ...
Hello friends, I hope you all are doing great. In today's tutorial, we will have a detailed Introduction to Structures in C#. It's our 17th tutorial in C# series. Structures are quite similar to classes but have few differences as well, which we will discuss today.
We have discussed C# Classes in 13th lecture, so you must read it once as we will use that knowledge in today's lecture as well. So, let's get started with Introduction to Structures in C#:
Introduction to Structures in C#
Structure in C# is a value type data type, created by using keyword struct, and can have fields, methods, properties, operators etc. just as in C# Classes.
Main difference between C# Class & Structure is that C# Class is a Reference Type Date type while C# St ...
Hello friends, I hope you all are doing great. In today's tutorial, we are gonna have a look at 3 Reasons To Switch To Cloud Storages. Even though Cloud storages are getting increasingly popular, there are still some dark clouds of misconceptions of stereotypes that shadow the reputation of the entire industry. A lot of users still believe that cloud storages are not safe, that it’s risky to trust sensitive personal and business information to a third-party server. Others, on the other hand, claim that Cloud storages are much more secure than local drives.
The truth, as in most cases, lies in the middle. It would be wrong to say that all Cloud storages are safe - it is indeed possible to encounter fraud a couple of times. However, it would perhaps ...
Hello friends, I hope you all are doing well. Welcome to the next tutorial of our Raspberry Pi 4 programming course. In the previous lecture, we interfaced LCD 16x2 with Raspberry Pi 4. Today, we will interface a keypad 4x4 to Raspberry Pi 4. In embedded projects, a keypad is used to get user input i.e. calculator, ATM keypad etc. Different types of Keypads are available i.e. 4x4, 4x3 etc.
So, let's get started:

We will need the following components in our today's project:Raspberry Pi 4Keypad 4x4BreadboardConnecting Wires
Keypad 4x4
A keypad is a collection of push buttons, arranged in a matrix form.Keypad 4x3 means the keypad has 4 rows and 3 columns and 12 buttons in total. A 4 by 4 keypad membrane has 8 pins in t ...
Hi Fellas! I am back to give you have a daily dose of valuable information so you keep coming back for what we have to offer. Today, I will discuss the details on the Introduction to PIC16F628a. It is defined as a self-contained 18-pin PIC Microcontroller that comes with memory, processor, peripherals and mainly used for embedded systems and applications.
Microcontrollers always remain a top priority for experts where automation is the main concern. Before the invention of microcontrollers, microprocessors were widely used for carrying out different functions related to industrial automation and processing applications. Both of them work identical in one way or the other, however, there are some exceptions i.e. microprocessors don't come with ROM ...
