Program Robots Like a Boss
In this tutorial I will show you how to setup and use an IR (InfraRed) remote controller with Arduino. You will learn how to map each button of the controller to a specific action, so you can make your Arduino programs more dynamic. After reading this post you will be able to fully integrate any … Read more
In this tutorial I will show you how to make the Arduino pulseIn() function non blocking, using interrupts. Actually what we’ll try to do is to reproduce the behavior of pulseIn() without using it. I will not explain what is pulseIn() and how it works here, for that please check this pulseIn() tutorial first. The … Read more
The Arduino pulseIn() function may be quite hard to grasp at first. However, this function can be very useful to be able to read data from certain sensors. In this tutorial I will explain what is a pulse, how the pulseIn() function works, and how to use it in your own programs. >> Watch this … Read more
So, you’ve been playing with your Raspberry Pi and the GPIO panel, and you’ve noticed that when you read the GPIOs, some of them give you the value HIGH (or 1) by default, some of them give you the value LOW (0). Why is that? In this tutorial I will show you what is the … Read more
Great, you’ve learned a bit of Python 3 with your Raspberry Pi and you might be wondering: how can you run a Python 3 script in the terminal? For now you may have used only the Thonny Python IDE, or any other easy-to-use system to write Python programs. This is perfectly fine, especially to start … Read more
In this ROS2 tutorial I will show you how to use an rclcpp parameter callback, so you can dynamically change parameters’ values while a node is alive. With parameters you can already change the configuration of the node at runtime. But after that, any change to any parameter won’t be taken into account. With a … Read more
What are the different Arduino variable types? Whether you are a complete Arduino beginner or you already know how to program, this guide will help you discover and all the most useful Arduino variable types. First of all, Arduino is a subset of C/C++, with additional functionalities related to the hardware features of the board. … Read more
In this Arduino tutorial I will show you how to turn an LED on and off with a push button. In fact, we’ll do 2 slightly different applications. First, we will power on the LED when the button is pressed, and power off the LED when the button is not pressed. And then we’ll modify … Read more
In this tutorial I will show you how to control an LED with your Raspberry Pi 4 (also works with Raspberry Pi 3 and 2) and Python 3. Controlling an LED is the first step you can take to discover how GPIOs work and what to do with them. After this you’ll be able to … Read more
Learning Python 3 with Raspberry Pi is a great idea. You will be able to write programs producing real physical results, while also learning more about computer science in general, system administration, hardware, etc. Programming is not only about smashing code into a text editor. To be able to write great programs you also need … Read more
