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 fi ...
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 a ...
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 ...
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 matr ...
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 ...
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 fu ...
