While Python is installed by default on all Raspberry Pi OS versions, this isn’t necessarily the case with PIP, the Python packages installer. As PIP is useful for most Python projects, you’ll often need to address this error as soon as possible. Here is how to do it. The error ‘-bash: pip: command not found’…
If you’ve upgraded to Bookworm and have used Python in your projects, you can’t have missed this change: they do everything to make you switch to virtual environments. What is this all about, and do you need to worry about it? Let me explain. Virtual environments in Python are isolated spaces for projects. Each virtual…
Ever wondered how some rooms only light up when someone enters the room? The answer is motion sensors. But what’s more unclear is how you would connect a motion sensor to a Raspberry Pi. Let’s see how it works. A motion sensor can be connected to the Raspberry Pi by using only 3 wires: power…
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. Overall, Python is still the best programming language…
Node-RED is a powerful tool that is often used on Raspberry Pi, but weirdly is no longer available by default on Raspberry Pi OS. If you’re looking to install it on your Pi but are unsure where to start, this is the tutorial you are looking for. I’ll guide you through the entire process step-by-step….
OpenCV is often used to promote Raspberry Pi capacities. Even if the Raspberry Pi is a cheap piece of hardware, showing it with a camera, using artificial intelligence and electronics is pretty impressive. But before doing all of this, you have to set it up correctly, and it isn’t straightforward for beginners. That’s why I…
If you’re new to programming and looking to get started with Python on a Raspberry Pi, Thonny IDE is a great choice. In fact, even as a seasoned developer, I tend to use it regularly for simple Python projects. I find it easier to stay focused on your code than on more powerful solutions. Thonny…
I’ve already covered many languages you can use with Raspberry Pi on this website (Python, C/C++, etc.). Node.js is another one you can try. Numerous libraries are available for it, so you can easily use the specific hardware on the Pi (GPIO, camera module, etc.). Let’s learn how to get started with it. Node.js is…
Creating user interfaces in Python for your Raspberry Pi projects is not as complicated as you might think, and it will highly improve the end-user experience (even if it’s only you). I recently tested a few Python libraries that allow you to create a GUI (Graphical User Interface), so I will share my favorites in…
