How to connect sensors to Raspberry Pi (step by step guide)
Chip Wired
by Chris
1y ago
I believe sensor projects are one of the best ways to use a Raspberry Pi. A Pi can easily be setup to collect data from sensors, and use that data to make decisions. This is fundamental to many great Raspberry Pi projects. When getting started with Raspberry Pi sensor projects, you might be wondering how to even connect a sensor to the Pi. In this guide I’m going to show you how to connect a sensor to the Raspberry Pi. Most sensors connect to the Raspberry Pi’s GPIO. Digital sensors can connect directly to the GPIO, while analog sensors need to connect via an analog-to-digital converter. Addit ..read more

Does Raspberry Pi have built in sensors?
Chip Wired
by Chris
1y ago
If you only have a Raspberry Pi – no additional wires, devices, or hardware – then what can you do. That’s something I wondered when I first got a Raspberry Pi. I quickly realised the best uses of Raspberry Pi are those that involve interaction with the real world – motors, displays, and sensors. But the Raspberry Pi itself is lacking a bit in sensors, and extras do have to be purchased. The only sensor built in to the Raspberry Pi is the CPU temperature sensor. This sensor measures the CPU temperature to trigger a shutdown of the Raspberry Pi if it gets too hot. It is possible to read the sen ..read more

Can Raspberry Pi be powered by USB? (tests included)
Chip Wired
by Chris
1y ago
“If it fits, it works” – this is not a philosophy that I’ve found to put your Raspberry Pi project at risk of not working. Even though the Raspberry Pi uses a USB connector for its power source, it is important to consider where that USB cable connects to. If it doesn’t supply enough power, your Raspberry Pi won’t work. It is not recommended to power a Raspberry Pi from the USB port on a computer. USB ports are often unable to provide sufficient current to match the power requirements of the Raspberry Pi. The Raspberry Pi will shut off immediately if sufficient current is not available. NOT RE ..read more

Wires for Raspberry Pi: Ultimate Guide to Types, Gauge, Costs

by Chris
1y ago
When I first started building circuits with Raspberry Pi, I was confused by the overwhelming choices for wires (and other components) that could be used in my circuits; I had no idea if I was choosing the right wire for my Pi and for my project. This guide is the culmination of my research and experience in choosing wires for use in Raspberry Pi projects. The focus of this guide is wires rather than cables. When building a Raspberry Pi project, it is best to use 22 AWG single-stranded copper wire with connectors suitable for the GPIO (female) and a breadboard (male). These are typically purcha ..read more

I love exploring ways a Raspberry Pi can replace a full desktop computer. This exploration includes finding ways to accomplish my day-to-day tasks on a Raspberry Pi, such as note taking. In this guide I’ve listed out some of the note taking apps that I tried out on Raspberry Pi, and how I went about installing them. A Raspberry Pi can take notes using Taskbook, Zim, or Tomboy-ng. These note taking apps offer graphical or command line interfaces that run on Raspberry Pi. The note taking app can be installed from a .deb file or by using the apt package manager. Some of the note apps I tried to u ..read more

by Chris
2y ago
I was trying to install some new apps on my Raspberry Pi (for note taking) and none of them were listed in the apt package manager. Instead, they offered me .deb files. After seeing some confusion about how to install .deb files on Raspberry Pi, I decided to put this guide together to help anyone else with the same issues. To install a .deb file on Raspberry Pi, open up a Terminal and navigate to the .deb file. Then use the apt install command to add install the app on the Raspberry Pi. This command will ensure all necessary dependencies are installed as well. Raspberry Pi can install .deb fil ..read more

I’m on a quest to find whether a Raspberry Pi can replace a desktop as a general-purpose computer. One of the tasks I do most frequently on my desktop computer is check my ChipWired email. In this guide I’m sharing some of the ways I’ve explored sending and receiving email using my Raspberry Pi. The best email clients for Raspberry Pi are Claws and Thunderbird, which offer a graphical interface to send and receive email, as well as a helpful setup wizard guide for adding new mail boxes. Python can also be used on a Raspberry Pi to send and receive emails using the smtplib and imaplib respectiv ..read more

Choosing Raspberry Pi or Arduino: 7 Things to Consider
Chip Wired
by Chris
2y ago
Choosing the best tools for a project is a core belief of mine given my background as an engineer. Some projects are better suited to small, efficient tools (such as Arduino), while others are suited to more complicated and capable devices (such as Raspberry Pi). I put together this list of things to consider when you’re trying to decide if you should use an Arduino or a Raspberry Pi for your project. When choosing between Raspberry Pi and Arduino, the important things to consider are how much power you have available, whether you need to use a display, and how you are going to communicate or ..read more

How much it costs to run a Raspberry Pi (measurements and calculation included)
Chip Wired

I wanted to know how much it costs to run my Raspberry Pi 4 if I left it running for a day, a week, a month, and even a year. To figure this out, I conducted over 30 measurements of how much power my Raspberry Pi used running various tasks, and calculated how much it would cost to run. I used a price of 16 cents per kilowatt-hour as taken from this source. A Raspberry Pi costs between 1.1 cents and 2.3 cents per day to run. This is equivalent to between $3.65 and $8.57 per year. The more expensive costs occur when the Raspberry Pi is running multiple apps intensively, such as busy web server ..read more

6 Ways to Stop a Program Running on Raspberry Pi

A frozen program running on a Raspberry Pi is likely consuming memory, power, CPU time, screen space, and is likely getting in your way. If a program is frozen it’s serving no purpose except to waste your resources. In this guide I’ve looked at a variety of different ways to stop a program running on a Raspberry Pi depending on how the program is running (in a terminal, as a script such as Python, and graphically). The easiest way to stop a program running on a Raspberry Pi is to open a terminal and use the kill command with the program’s process ID. Finding the process ID can be accomplished ..read more
