In this case I am going to bring you a guide about the basic circuit and programming of an ATTiny85. The basic circuit is very simple and only needs a resistance as an external component, unless we want to vary the clock speed with an external crystal. To keep this guide simple for the time … Read more
In this post I am going to talk about TaskScheduler. TaskScheduler are, as the name implies, an object that will allow us to create periodic tasks without having to use millis or conditionals. How do they work? TaskSchedulers are objects to which you can add tasks and they are in charge of executing them from … Read more
One very useful thing I would like to talk about is Interruptions in Arduino. An interruption is a signal of either Hardware or Software that causes our Arduino to exit the main program and execute an indicated function. Before starting with this, there are a number of important considerations to keep in mind: As I … Read more
Hello, today I bring you a basic tutorial about the pull-up and pull-down resistors, and the INPUT_PULLUP input mode of the Arduino pins. This type of resistance will help your Arduino not be affected by electrical noise and receive errors in your measurements such as false pulsations on a button. What is HIGH, LOW or … Read more
One of the things that we all ignore many times (I confess that I have ignored it until now), is the EEPROM memory of our Arduino. This memory is not very large, but it has the advantage that it survives the shutdowns of our microcontroller. That is why in this article I will teach you … Read more
Today I bring you a guide on how to make a two-way I2C communication between Arduino. I have recently started tinkering with this protocol because I am interested in a project that I have in mind, and after a few tests I have been able to verify that two Arduino masters can communicate without problems. … Read more
One importatn thing to know are the variable data types existing on Arduino, and that is why I’ll try to talk about Variables Types in Arduino. For starters, here you have a table of the different types, their sizes (something very important to consider), and links to each one in the official documentation. Then I … Read more
In this post I will try to show you some tips on how to save space in the SRAM memory of your Arduino. As we all know, our Arduino is limited in resources, and that is why we have to make the most of our ingenuity and the tools they provide us to try not … Read more
