There are a plethora of tools available for the Raspberry Pi that system administrators can use to monitor network traffic. Newer Raspberry Pi models even come with a built in WiFi chip in addition to the traditional Ethernet port, giving us even more options for connecting to networks and monitoring traffic. Network monitoring can be useful for troubleshooting connectivity problems or identifying bottlenecks that are slowing down connections.

Set up Raspberry Pi as Router
The Raspberry Pi can be a great choice if you want to implement a customizable router for your home network. Rather than paying big bucks for a router which is not as configurable due to its proprietary software, the Raspberry Pi can be transformed into a router while retaining its default Linux operating system, with which system administrators are very familiar. Firewall rules and network monitoring are made easy when all of the traffic is passing through the Raspberry Pi instead of a locked down router.
Raspberry Pi 4 enable UART
Among the GPIO pins on the Raspberry Pi are two that are capable of UART (Universal Asynchronous Receiver/Transmitter). UART is a serial connection which, when utilized on the Raspberry Pi, can send data between the Raspberry Pi and an external device. It is one of simplest connection types available on Raspberry Pi, which means it is easy to use but also more limited in functionality.
How to stream video on Raspberry Pi
A Raspberry Pi can have a myriad of specialized uses, and streaming live video is one of them. There are multiple camera models sold for the Raspberry Pi, which you can browse over at the official website. These cameras plug in via ribbon cable directly to the board of the Raspberry Pi, and then it is an easy set up to stream the video or take still pictures from the camera.
Raspberry Pi black screen after boot
Although it is not a common error, some users may encounter a black screen when using a Raspberry Pi. The error is most likely to occur when first booting the Raspberry Pi, giving users very little opportunity to perform any kind of investigation into the problem for troubleshooting. In this tutorial, we will look at some ways to solve the black screen problem that occurs when booting a Raspberry Pi. This will include a few different methods, as the exact cause can vary and sometimes be hard to pinpoint.
How to turn a Raspberry Pi into a surveillance system with ZoneMinder
ZoneMinder is a free and open source closed-circuit television software we can install on our Raspberry Pi (or any other Linux system) to monitor and protect our home, or whatever we deem valuable. ZoneMinder is easy to install, supports a vast selection of cameras, and has also APIs for third party software integration.
How to check GPIO status
The GPIO (General Purpose Input/Output) pins of the Raspberry Pi are how the device can interface with external hardware components. It is how things like sensors and actuators plug into the Raspberry Pi, and allow users to control such devices from the Raspberry Pi itself. Something as simple as turning an LED on or off will require setting the pin to which it is plugged in to either true or false, which changes the current status of that pin.
Raspberry Pi as Music Streamer
Thanks to its small size and simple requirements, the Raspberry Pi can be transformed into a variety of different specialized devices. One such role that it can fill is that of a dedicated music streamer, or jukebox. Whether you have your own music files (MP3, FLAC, etc) already downloaded and want to stream them to speakers around the house, or you rely on streaming services like Spotify or Pandora, utilizing the Raspberry Pi as a music streamer is a great way to enjoy some tunes. In this tutorial, we will go over the step by step instructions to help you turn your Raspberry Pi into the ideal music streaming device.
Raspberry Pi Kali Linux headless setup
Kali Linux is one of the many operating systems that has full support for the Raspberry Pi, thanks to the ARM installer images. Combining Kali with a Raspberry Pi essentially gives you a portable penetration testing machine. Kali Linux can be installed and run without a monitor, keyboard, or mouse, so you will not need to worry about plugging in any peripherals to the Raspberry Pi.
Reviving Retro Games: Using Raspberry Pi for Emulation
While a Raspberry Pi can serve many purposes, one role that it fills surprisingly well is that of a retro gaming console. The idea is to load up the Raspberry Pi with as many emulators and ROMs as possible, and then you have a portable, HDMI capable gaming machine in the palm of your hand. Plug it into any monitor or TV, and use your keyboard and mouse, or even USB or Bluetooth controller to play some retro titles.
How to dual boot multiple OS’s with Raspberry Pi
Since there are so many operating system choices for the Raspberry Pi, why limit yourself to just one? It is possible to dual boot multiple operating systems on the Raspberry Pi, the same as is traditionally done on any ordinary desktop system. It is not necessary to have multiple SD cards lying around with different operating systems on them, popping them into your Raspberry Pi whenever you want to boot into a different OS. Instead, we can put two or more operating systems on the same SD card.
Raspberry Pi vs Arduino: Which is Best for Your Project?
When it comes to single board computers and do it yourself projects, two of the most popular choices are the Raspberry Pi and Arduino. Both of these devices have their own unique advantages, and picking the right one for your project can make a big difference. In this tutorial, we will go over the Raspberry Pi and Arduino in fine detail, highlighting their pros and cons, and helping to guide you on making a decision between these single board computers for your project and its specific needs.
