This project, although simple, contains several elements essential for working with Arduino and in general with microcontrollers. In addition to working with the RGB diode, the project involves using the analogWrite function to work with (certain) digital pins. Using this function implies the use of PWM signals, and also includes usage of user functions.

In the age of classic cameras and darkrooms, photography involved developing images in light-proof rooms using chemical mixtures. To ensure successful image development, preventing light from entering the darkroom was crucial. This project involves developing an electronic circuit to control the operation of two LEDs, indicating the darkroom’s availability.

In today’s tech-driven world, laptops have become indispensable. They offer numerous benefits like portability and compactness. However, they also come with certain drawbacks. One major disadvantage is the limited battery life, and another significant issue is the small screen size. When you’re accustomed to working on a 27-inch desktop monitor, a laptop screen can feel quite cramped.

I have been using Fedora Linux for some time now. I switched from Arch Linux in search of some more “peaceful” distribution. However, I’ve been using Arch for too long to accept the KDE spin of Fedora that comes with a bunch of bloatware by default. I searched and of course found a tutorial for a minimal installation of the KDE Plasma environment on Fedora. I wrote about it almost a year ago, and now a new version is coming!

Instructions for installing ArchLinux using the installation script ArchFi (and then ArchDi) is the first in a series of texts dedicated to the comparison of different ways of installing the ArchLinux distribution. This text is also an installation guide, but using the officially supported script – Archinstall. I will refrain from giving too many impressions, that remains for the third and last text in this area. I’ll just say that it’s a much simpler way to install ArchLinux and a minimal desktop environment offered from the list.
Read More »Arch Install Made Easy: Archinstall Guide It’s been a while since my last guide for installing ArchLinux article that covered the classic installation method (reading the documentation and typing command by command until you get to a working system). The following is a new one that will describe how to install this popular Linux distribution, using the Archfi installation script, I mentioned earlier. This text will be part of a trilogy that will consist of: Archfi script, Archinstal script and finally their comparison. Somehow, it just happened that a few days ago, a new version of the Archfi script was released after less than a year and a half, so let’s see how it all works (and it works 🙂 ).

This project makes it possible to do it in a simple, easy and relatively inexpensive way using an Arduino and an ultrasonic sensor HC-SR04. The only limitation imposed by the application of this sensor is the maximum range of 4m. For the needs of a hobby project in the household, it can get the job done, and quite well.

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.
