Have you ever wondered how cars pass through toll booths without stopping, or how people enter buildings with a card? That’s thanks to RFID technology. Trying to replicate this on your Raspberry Pi can feel daunting, but I’ve done it and will share all the steps with you in this article. Reading and writing data…
While the Raspberry Pi is often associated with the same programming language (Python), it doesn’t mean it’s the only option. Depending on your project, skills and needs, you might want to consider other options. Let’s discuss the best programming languages you can try for your next project.

A Raspberry Pi only has one Ethernet adapter, so it isn’t necessarily the best device to build a network router, but we can still use the wireless adapter on one side of the router. I’ll show you how to do this in this article. A Raspberry Pi can be used as a network router by…
While Raspberry Pis can be used as a desktop, they are also often used in projects without a monitor or keyboard plugged into it. In these projects, a bit of pre-configuration to skip the welcome wizard can help get access to them directly after the first boot. The easiest way to pre-configure a Raspberry Pi…
When you plug a Raspberry Pi into the network and boot it, it will generally get a “random” IP from the DHCP server. This IP address might change almost every time you use it, which is not convenient at all. Let’s see how to set a fixed IP address, so the Raspberry Pi always use…
While a Raspberry Pi is pretty reliable and can run 24/7 for weeks without a problem, it can also be annoying at times. Do you have a black screen and have no idea what’s going on? I’ve been there, let me give you a few tips on how to fix that quickly. For an existing…
The “apt” or “apt-get” commands are essential on Linux systems. But what do you do when they’re not available and all you get is a “command not found” error message? Well, I can help. The “apt-get: command not found” error most likely happens when trying to use the APT package manager on a non Debian-based…
Most Raspberry Pi models have one Ethernet port and one Wi-Fi adapter, making them the perfect device to become a Wi-Fi access point. Whether you do this because you don’t have any Wi-Fi network yet to create a separate network on your LAN or for other reasons, I’ll show you the steps to get you…
The Raspberry Pi 400 has its own category in the Raspberry Pi model line-up and, with it, it brings a ton of specific questions from potential buyers, owners and other curious people. I’m the happy owner of a Pi 400, and I’ll answer all of your questions in this article. I’ve sorted the questions and…
The new Raspberry Pi OS version (codename “Bookworm”) is now officially available. While it’s recommended to install a fresh new version, it’s still possible to try an upgrade on non-critical systems. Let’s discuss your options there. As a general rule, it’s always risky to try an upgrade from one major version to the next without…
