Hello friends, in today's post we are gonna have a look at Interfacing of Keypad with 8051 Microcontroller in Proteus ISIS. In the previous project, we have seen the Interfacing of LCD with 8051 Microcontroller and I have told there that LCD is a great debugging tool as we can print our data on it and can display different values and that's what is gonna done in today's post. Today, I will get the values from keypad and then question is how to know that we are getting the correct values. So in order to do so, we will display these values over LCD. So, that's how we are gonna use LCD as a debugging tool. As the debugging is concerned, there's another great tool for debugging which is called Serial port, we can also display these values over to Seri ...
Fluid mechanics is considered to be one of the essential branches of Mechanical Engineering. Fluid Mechanics comprises two words, fluid, and mechanics, with different meanings and research criteria. In this article, I will extensively introduce fluid mechanics and its importance in daily life. So without wasting any time, let us start:
Introduction to Fluid Mechanics
What is Fluid?
We remember in the early classes, we used to study three states of matter, and afterward, they became four named: Solid.Liquid.Gas. Plasma.
The definition of fluid is the state of matter that can be liquid or solid. We might have noticed that whenever the matter is in any stage, the criteria to know its state is to understand how much stress it can bear, and we name th ...
Hello friends, hope you all are fine and having fun with your lives. Today's post is about the Controlling of Servo Motor with Arduino in Proteus ISIS. Servo Motor is a common motor used in engineering projects for precise circular motion. We can move the servo motor at any desired angle, which is not possible in the case of other motors i.e. Stepper or DC.
For example, suppose I want to move an antenna at a precise angle of 47.5 degrees then if I use DC Motor, I have to use an encoder. So, in such cases instead of using a DC motor, I will prefer Servo Motor.
I have already posted Angle Control of Servo Motor using 555 Timer in which I have controlled servo motor using 555 timer and another tutorial about Controlling of Servo Motor using PIC Micro ...

Thank you for joining us for yet another session of this series on Raspberry Pi programming. In the preceding tutorial, a facial recognition system on a Raspberry Pi 4 was used to develop a smart security system. We also learned how to create a dataset using two Python scripts to train and analyze a series of photographs of a certain person. This tutorial will teach you how to install pi-hole on a Raspberry Pi 4 and use it to block advertisements from anywhere. This is a great initiative for folks who are tired of annoying pop-up adverts while browsing. First, we'll learn how to set up the pi-hole without the need for an environment, then we'll use Docker to install pi-hole, and ultimately we'll see how we can access it from anywhere.
Prerequisites
A minimum of 512MB ...
Hello friends, I hope you all are having fun. Today, I am going to share the 9th tutorial of Section-III in our Raspberry Pi 4 Programming Course. In the previous tutorial, we interfaced an air pressure sensor BMP180 with Raspberry Pi 4. In this tutorial, you'll learn how to interface an MQ-2 gas sensor with a Raspberry Pi 4. Many apartments, residences, and workplaces rely heavily on these gas sensors to detect smoke or gas and alert the appropriate personnel in an emergency. In addition to gas and smoke, this sensor is sensitive to various odorous gases.
Project DescriptionToday, we will interface a gas sensor MQ-2 with Raspberry Pi 4 and will display the values on Raspberry Pi Console Window.
Components Required
These are the components use ...
Hello friends, I hope you all are doing great. In today's tutorial, I am going to share Top 5 Reasons a Survivalist Should Be an Amateur Radio Operator. With 2021 setting in, are you well prepared to survive if the world goes down? We live in uncertain times, and the pandemic has taught us that what we plan today might not be applicable tomorrow. Simply put, like survivalists, we should be mentally and physically tough and all geared-up for emergencies, disruptions, and the breakdown of society. If you are currently living the survival mode, also known as the prepper lifestyle, you are heavily self-reliant. We expect you to have your backpack ready with all the right emergency tools and gadgets, such as a survival knife and a ham radio set. Read ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to share my knowledge on Introduction to LM348. LM-348 i basically a General Purpose (GP) Operational Amplifier. It is an independent and quadruple operational amplifier. LM 348 has similar characteristics in comparison to uA741. It is an internally compensated amplifier having high gain.
LM-348 has four internal amplifiers. We can achieve isolation between these amplifiers by biasing each of the amplifier independently. This isolation can be done using different techniques e.g. layout technique. It can be used at several different places where amplifier matching is needed. LM 348 has very low supply current drain as compared to the standard 741. Moreover, I ...
Hello friends! I hope you are doing well. Today, I will give you a detailed overview of the Electrocardiogram, abbreviated as ECG or EKG. An electrocardiogram is a biological test used to convert the activities of the heart into electrical signals, and these signals are then read by specialized surgeons to predict heart conditions. In simple words, ECG is used to record the rhythm of the heart activity on a moving strip of paper. Related doctors are able to read the spikes and dips on the paper and can decide, whether the heart is in normal condition or not. These spikes or dips are usually known as waves.
As we know, the heart is a muscular pump consisting of 4 chambers. There are two lower chambers and two upper chambers. Lower chambers are know ...
Hello friends, I hope you all are having fun. In today's tutorial, we are going to discuss How to use Arrays in C#. It's our 6th tutorial in C# series and currently we are focusing on basic concepts in C#.
Without understanding these simple concepts, we can't move forward. So, let's get started with Arrays in C#:
How to use Arrays in C# ???
An array (base type System.Array) is a collection of similar (like-typed) data types, called by a common name. Each data item is referred as an element of array and is assigned an index starting from 0.
As C# array is an object so we can find its length using member length, which is actually a count of total number of data items in that array.
Arrays are reference types and implement IEnumerable that' ...
Hello friends, I hope you all are fine and having fun with your lives. In today's post, we are gonna have a look at How to use C# ArrayList. I am gonna explain it in detail what is C# ArrayList and how to use C# ArrayList. But before going into the details of today's tutorial, you must first have a look at my previous tutorial which is How to use C# Array??? because C# ArrayList is quite similar to C# Array.
I am gonna use the same project which we have designed in our first lecture on C# named as Introduction to C# Windows Forms. So, you should also use the same project and as we know this project has one Button and one Text box. Just a recall that I have changed the Text of the button to Click Here and the name of the button to ClickHere. Simila ...
