Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to explain you about Introduction to LM386. Its a power amplifier specially designed for low voltage consuming applications. The gain of LM 386 is set around 20 internally. But the gain could be increased due to the insertion of external resistor and capacitor between the pin number 1 and 8. The gain could increase to any value from 20 to 200.
The LM-386 inputs are ground referenced. The output are biased to the half of the input voltage levels automatically. When LM 386 operates on 6V, its quiescent power drain is around 24mW. This property of LM-386 makes it ideal for the battery operation. Its major features include battery operation, minimum external p ...
Hi Friends! Hope you’re well today. I welcome you on board. In this post today, I’ll explain how a 21st century tire industry will revolutionize the market.
Tire changing and purchasing is a controversial issue for many Americans, with non-insurance purchases that are often arguably expensive. This is set to change with the rise of Tire Agent, who TechCrunch highlighted as receiving $5m in new financing in their bid to remove the mystique from tire purchasing and installation. Using smart data, they’re aiming to pull together buyers, sellers, and mechanics across the country and provide a truly equitable purchase map for those in need.
With this data, the industry will be revolutionized, and technology will change how motorists deal with their t ...
Hello readers, I hope you all are doing great. In this tutorial, we will learn how to interface the BMP280 sensor with the ES32 module to get temperature, pressure and altitude readings. Later, in this tutorial, we will also discuss how to upload these sensor readings to a web server.
BMP280
BMP280 or Barometric pressure sensor is a module used to measure temperature pressure and altitude. The small size and low power consumption feature of this sensor makes it feasible for battery-powered devices, GPS modules and mobile applications etc.

The BMP280 is the product of BOSCH which is based on Bosch’s proven Piezo-resistive pressure sensor technology featured with high accuracy, long term stability, linearity and high EMC robus ...
Hi Guys! I hope you are doing great. In today's tutorial, I am going to tell you about enhancing home security through electrical engineering. And the Importance of enhancing the security of all home areas through electrical engineering.
Underneath the sometimes chaotic surface, Pakistan has a burgeoning smart city scene that has led to the country becoming a member of the internationally recognized Smart Cities club. With Lahore as the exemplar in the region, this has nevertheless raised the question of security. As homes become ever more one with smart systems, digital-electrical conveniences and indeed the wider world, electrical engineering solutions are providing an inbuilt, solid solution to security worries.
Protection Against Fire

Hello peeps! I hope you are having a good day. We all know carbon monoxide is a dangerous and harmful gas that can even be fatal. It is a colorless and odorless gas so it is difficult to sense its presence therefore, different types of sensors and indicators are required to make the places safe especially those where there is a chance for carbon monoxide gas production as a byproduct. Here, one of the most promising detectors is the MQ-7 carbon monoxide sensor which instantly detects and indicates the presence so the users may save their lives. This is the most popular choice for this purpose because of its low cost, high performance, and instant response.
This article will commence by introducing the MQ-7 carbon monoxide sensor. Subsequently, we will delve into essential details from it ...
Hello students! Welcome to the new tutorial on Python. We all know that Python is one of the most popular programming languages, and there are hundreds or thousands of developers that are earning a handsome amount with the help of this easy programming language. In the previous lecture, we studied the range in the sequence, and in the present class, our concern is having the command on the sets in Python. We know you are curious about the set's details, but before this, I want to share the list of topics that will be covered in this class.
What is a set in the Python programming language?
What are some properties that distinguish the set from other data types?
What is the mutable data type, and how is it related to the set?
Introduction of the Jupyter notebook.
Can we have duplicate ...
Hello readers, I hope you all are enjoying our Raspberry Pi Pico programming series. In our previous tutorials, we learned how to access Raspberry Pi Pico’s GPIO pins for both input as well as output operations. For demonstration, we used LED as an output component and a push button as an input component.
Now let’s learn how to interface sensor modules with the Raspberry Pi Pico module. So, in this tutorial, we will learn how to interface the DHT11 sensor with the Raspberry Pi Pico module and fetch the observed data (from its surrounding) using the MicroPython programming language.
Before writing the code for interfacing and fetching the data from the respective sensor, let’s first have a look at the working operation, features and properties of the DHT sensor.

Hello friends, hope you all are fine and having fun with your lives. Today, I am going to start a new series of tutorials on C++ Programming. and here's my first tutorial in this series which is Introduction to C++. I am gonna share a lot of tutorials in this series in future, in which I am gonna explain all about C++. In the initials tutorials, we will cover the basics of C++ Programming and later on we will also cover the pro concepts of C++ Programming.
I am planning on posting around 20 to 30 tutorials in this C++ Programming series, and I am quite sure that it will cover all about C++ and if you are a new learner then it will help you quite a lot.. I have started this series on a request of one of my readers. He suggested me this idea and I l ...
Hello friends, I hope you all are doing great. In today's tutorial, we are gonna have a look at detailed Introduction to HC-06. HC-06 is a class 2 slave Bluetooth module designed for serial communication. Once it is paired to a master Bluetooth device such as PC, smartphones, and tablet, its operations become easier to the user. It sends and receives data in a bidirectional manner.
HC-06 is used in different devices which works on Bluetooth for sending and receiving data. In today's post, we will have look at its pinout, working, circuit diagram, protocol, etc. I will also share some links of projects where I have interfaced it with Arduino and some other microcontroller. Friends if you have any questions please ask in comments I will try my bes ...
Hi Guys! Hope you’re well today. I welcome you on board. In this post today, I’ll detail the 7 best Arduino starter kits for beginners.
Arduino boards are particularly introduced for people with little to no knowledge about programming and electronics. These boards are the improvised version of microcontrollers. If you’re a student or someone planning to get your hands dirty with some electronic projects, Arduino boards are a great way to whet your appetite.
Arduino kits house many essential components required to start working with Arduino boards. These kits are developed for people who struggle to get a hold of the nitty-gritty of programming Arduino boards. These Arduino basic kits come with instruction manuals that detail the step-by-step pro ...
