Although this assigment raises some ethical issues that I disagree with, I will deal with solving and explaining this problem. The assigment is to design a game of chance for elementary school students (assigment says so), where a randomly chosen number from 1 to 6 will be printed on the LCD display – in simpler terms, it is a simulation of throwing a dice.

Summer has started and hiding from the heat, a new video tutorial arrives. The project of creating a simple advertisement using the MAX7219 integrated circuit – LED matrix driver, LED matrix module and Arduino. This task can be solved in a simple way by using external libraries for working with the MAX7219 and the LED matrix in a few lines of code. As a result, an attractive text animation is obtained. It is possible to connect several LED matrix modules, the complete impression would be better.

For the purposes of creating a simple advertisement, i.e. for a project in which an LED matrix will be used to display animated text, I used two additional libraries. I chose them because I think it was the simplest solution for working with the MAX7219 IC and animating the text. To begin with, a little about the libraries themselves, and the project will be described in the following text. The libraries in question are MAX72xx and Parola.

Here you will find detailed instructions and explanations of the program. I started with the 6th task from the collection, and there will be more similar texts soon. The practice so far has been to make a video clip and explain the task through text on the blog, and now a document will be available for download.

It has been a year since I embarked on completely new waters in my career. I never dreamed I would work in education, but my path took me right there. I emphasize at the beginning, I will not write what it is like to work in education, but how it affected me, my plans for the future and personal development.

This time, a widespread component that is an indispensable part of any embedded system will be covered. It is a component whose purpose is to display data – textual or numerical, LCD module 1602a. Introduction to the characteristics of the component, mode of operation and its programming will be illustrated with the help of two simple programs (sketches). The first is “Hello, world!”, Which performs a simple display of textual data on the display, while the second includes a display of data obtained from the keyboard.

After a while, I will talk about Fedora again, because during the previous distro-hopping , Fedora generally left a positive impression on me. I may have been a little harsh to the Gnome environment, but in any case, this distro received a passing grade. Maybe even a C+! Between versions 34 and 35, I noticed significant improvements in the package manager, ie its speed. This text brings one more thing, and that is the bash script for installing Fedora with KDE Plasma environment and all the basic programs to use.

The Arduino Mega offers 54 digital pins, so you can consider purchasing such a microcontroller. Another solution that allows you to increase the number of pins is to use shift registers. In this case, we are talking about the shift register 74HC595. How this is achieved, how a scroll register works and how to use it with an Arduino UNO controller is the topic of this video tutorial and text.
