Program Robots Like a Boss
In this tutorial I’ll show you how to write an Arduino String to the EEPROM memory, and then read it again. The EEPROM memory lets you save values on your Arduino board so you can retrieve them even after you reboot the board. This is very handy when you want to save some settings/data to … 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 are using Arduino and you wonder if you can use the Cpp STL library in your code. The good news is: yes that’s possible! Even if some feature will still be lacking, or some others will be limited, you will be able to use things like std::vector and std::string in your Arduino programs. … 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
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 I2C protocol. The Raspberry Pi will be configured as a master, and the Arduino as a slave. You’ll see how to setup the communication, read an write, thanks to … Read more
You want to create a nice robotics, electronics or domotic application and you wonder: when to use Arduino vs Raspberry Pi ? Could your application run with an Arduino board only, or a Raspberry Pi board only? Do you need both? In this post I’ll give you some tips on when to use each board. … Read more
Arduino protothreads, when to use them, how to use them, and why? In this tutorial I’ll show you, step by step, how to use protothreads in your Arduino programs. First I’ll give you a template that you can use for any protothread you create. Then you’ll see more complex examples and how to use multiple … Read more
What are Arduino Interrupts? How to use them? What should you know about them? In this Arduino Interrupts tutorial I’ll show you an example of when you can use interrupts and how to handle them. I’ll also give you a list of important points you should pay attention to, because, as you’ll see, interrupts are … Read more
This tutorial is an introduction to Arduino Object Oriented Programming. If you’re already programming using C++ and OOP, and want to start writing Arduino OOP code, you’re in the right place. I’ll show you through some examples how to re-write some of the most common Arduino tutorials using the OOP way. At the end of … Read more
When using the Arduino library, you have two simple ways of getting the current time since the Arduino board started: millis() and micros(). Those are very useful functions that you need in almost all your programs. For example, they will allow you to write multitasks programs very easily, and thus avoid using the delay() function. … Read more
