Thank you for being here for today's tutorial of our in-depth Raspberry Pi programming tutorial. The previous tutorial taught us how to install a PIR sensor on a Raspberry Pi 4 to create a motion detector. However, this tutorial will teach you how to connect a single seven-segment display to a Raspberry Pi 4. In the following sections, we will show you how to connect a Raspberry Pi to a 4-digit Seven-Segment Display Module so that the time can be shown on it.
Seven-segment displays are a simple type of Display that use eight light-emitting diodes to show off decimal numbers. It's common to find it in gadgets like digital clocks, calculators, and electronic meters that show numbers. Raspberry Pi, built around an ARM chip, is widely acknowledged as ...
Legacy software refers to a business operating software that has been in use for a long time. This is older system software that is still relevant and fulfills the business needs. The software is critical to the business mission and the software operates on specific hardware for this reason.
Generally, the hardware in this situation has a shorter lifespan than the software. With time, the hardware becomes harder to maintain. Such a system will either be too complex or expensive to replace. For that reason, it continues operating.
What is a Legacy System?
Legacy software and legacy hardware are often installed and maintained simultaneously within an organization. The main changes to the legacy system typically only replace the hardware. That helps ...
Hello geeks, welcome to our new project. In this project, we are going to make a very interesting project. I think most of us have seen the scoreboards in sports, after looking at that, have you ever wondered about the working of it. Therefore, this time, we will be making something like that only with some extra features. So basically that score board is nothing but a counter which counts the scores. Most of the geeks who have an electronics background or have ever studied digital electronics must have heard about the counter.
Here, in this project, we are going to make an Up-Down counter. A simple counter counts in increasing or decreasing order but the Up-Down counter counts in increasing and decreasing order, both depending upon the input it h ...
Hello friends. In this lecture, we are going to have a look at the different kinds of MATLAB data types.
As we have already seen in previous lectures, MATLAB stands for MATrix LABoratory and allows us to store numbers in the form of matrices.
Elements of a matrix are entered row-wise, and consecutive row elements can be separated by a space or a comma, while the rows themselves are separated by semicolons. The entire matrix is supposed to be inside square brackets.
Note: round brackets are used for input of an argument to a function.
A = [1,2,3; 4,5,6; 7,8,9];
An individual element of a matrix can also be called using ‘indexing’ or ‘subscripting’. For example, A(1,2) refers to the element in the first row and second column.
A larger matrix can al ...
Hello geeks, welcome to our new project. We are going to make an important project which will be very useful for us in our daily life which is a variable DC power supply. As engineers who work with electronics need different voltage ranges of DC power supply for different electronic projects and components. It becomes very clumsy and hard to manage different power supplies because of wires which are connected to it and each power supply consumes an extra power socket as well.
So in this project, we will overcome this issue and learn to make an adjustable DC power supply, in which we will get a wide range of voltages.
Software to install
We will make this project in the simulation, as it is a good practice to make any project in the simulation fir ...
Hello friends! I hope you all had a great start to the new year.
In our first lecture, we had looked at the MATLAB prompt and also learned how to enter a few basic commands that use math operations. This also allowed us to use the MATLAB prompt as an advanced calculator. Today we will look at the various MATLAB keywords, and a few more basic commands and MATLAB functions, that will help us keep the prompt window organized and help in mathematical calculations. We are also going to get familiar with MATLAB’s interface and the various windows. We will also write our first user-defined MATLAB functions.
MATLAB keywords and functions
Like any programming language, MATLAB has its own set of keywords that are the basic building blocks of MATLAB. These 20 building blocks can be called by simply ...
Hello Friends! I hope you all are doing great welcoming 2022. With the start of the New Year, we would like to bring to you a new tutorial series. This tutorial series is on a programming language, plotting software, a data processing tool, a simulation software, a very advanced calculator and much more, all wrapped into one package called MATLAB.
We would welcome all the scientists, engineers, hobbyists and students to this tutorial series. MATLAB is a great tool used by scientists and engineers for scientific computing and numerical simulations all over the world. It is also an academic software used by PhDs, Masters students and even advanced researchers.
MATLAB (or "MATrix LABoratory") is a programming language and numerical computing environm ...
Hello student! Welcome to The Engineering Projects. We hope you are doing good. We are glad to introduce and use the Solar Panel Library in Proteus. We work day and night to meet the trends in technology. This resulted in the design of new libraries in Proteus Software by TEP and today we'll talk about the project based upon one of our library i.e, Solar Panel.
Solar Panels work very great in this era when all of the scientists are working to have a power source that is cheap, environmentally friendly, and clean. Solar energy fits in all these dimensions. We are designing a solar inverter in our today's experiment. This inverter is the best idea for the engineering project because it has endless scope, it is easy and trouble-free. In this report, y ...
Hey pupils, welcome to The Engineering Projects. We hope you are doing great. In today's simulation in Proteus ISIS, we'll seek the knowledge of an interesting topic. We are going to design a Television remote jammer in Proteus. We all are familiar with the TV Remote controller device and know it works when a light signal emitted by it is sensed by the television. Have a glance at the topics we will see in detail today:
Introduction to 555 Timer TV Remote Control Jammer.
Components of the circuit.
Working principle of 555 Timer Jammer.
Simulation of the Jammer of TV Remote Control using 555 Timer.
Moreover, you will also learn some interesting facts about the topic in DID YOU KNOW sections. let's jump to our first topic.
