Program Robots Like a Boss
Looking for Raspberry Pi tutorials? You’ve come to the right place.
Raspberry Pi is a very small and powerful board. You can use Raspberry Pi in many different applications: home automation, security system, robotics, web server, etc.
The online community around Raspberry Pi has been growing a lot over the past few years. And it’s still growing! Thus, learning how to use and program your Raspberry Pi will allow you to build many amazing projects, and share them with other people. It will also be very easy to get help online, through forums or tutorials like the ones below.
The Raspberry Pi tutorials you’ll find here are mostly focused on programming and robotics.
Here are some of the topics we cover about Raspberry Pi (non exhaustive list):

In this tutorial I’ll show you how to create a ROS Python Subscriber on your Raspberry Pi. This is the direct following of how to create a ROS Publisher on Raspberry Pi. Please check out this previous tutorial first, before you continue. In the first tutorial you have seen how to read the state of … Read more
In this tutorial I’ll show you how to write a ROS Python publisher on your Raspberry Pi. With the following code example you’ll learn how to publish a GPIO state with ROS. For that we’ll use a simple push button with a minimal hardware setup. You’ll see all the steps, from setting up the environment, … Read more
In this tutorial I’ll teach you how to use GPIO interrupts on your Raspberry Pi, thanks to the RPi.GPIO library. You’ll see: Why and when you need interrupts. How to use interrupts in your programs. 3 working examples to practice on different situations. This tutorial works on Raspberry Pi 4 (and earlier, 3B, 3B+), with … Read more
In this tutorial I’ll show you how to communicate between a Raspberry Pi and an Arduino board via Serial communication. First, I’ll quickly explain what is Serial communication. Then you’ll see how to setup your hardware and software, and we’ll dive into the Python code (Cpp for Arduino). A basic example at first, leading to … Read more
So, you’ve developed a nice ROS application, which can be launched with a single launch file: great! But… There is still a problem. Actually you have to manually launch this file with a command line tool (roslaunch), and you wonder how you could make your application automatically start when you boot your computer… Or your … Read more
Raspberry Pi hardware permissions can be quite tricky. So, you are using hardware functionalities with your Raspberry Pi 4 (or 3B, 3B+), and always getting errors such as “Permission denied”? This might be the case if you use I2C, SPI, UART, or simply the GPIOs on the Pi, with a user that isn’t root. In … Read more
WiringPi is a Cpp library for Raspberry Pi. With this library you can use many of the functionalities provided by the GPIO header: digital pins, SPI, I2C, UART, etc. Although there are many Python libraries for Raspberry Pi GPIOs, Cpp is quite a bit behind. Fortunately, there is WiringPi. In this post you’ll install WiringPi, … Read more
In this tutorial I’ll show you how to use and compile WiringPi in your ROS Cpp nodes, so you can talk to hardware devices from your ROS application. Make sure to read this introduction to WiringPi before if you don’t know the library well. The WiringPi library is a great tool for Raspberry Pi (4, … Read more
In this tutorial I’ll show you how to communicate between a Raspberry Pi 4 (also works with 3, 3B, 3B+) and an Arduino (Uno), using the SPI protocol. The Raspberry Pi will be configured as a master, and the Arduino as a slave. On Raspberry Pi we’ll use the WiringPi library inside a Cpp code … Read more
