Welcome to the Arduino Tutorials Hub—your one-stop repository for mastering Arduino programming and hardware integration! Whether you're a beginner or an advanced user, these step-by-step guides will ...

This tutorial was last updated on May 2025 to test the code for the latest Arduino development boards, including the Arduino UNO R4. If you are interested in programming microcontrollers using Python, ...

Programming Arduino UNO for multitasking will only require the logic behind how millis() work which is explained above. It is recommended to practice blink LED using millis again and again to make the ...

The Arduino Uno-compatible board has an MCS-51 (often called 8051 instead) instead of the usual ATmega328P/ATmega168. Specifically, [ElectroBoy] uses the AT89S52 .

We have been working hard to make sure the UNO R4 is highly retrocompatible with code written for UNO R3, including tutorials and libraries.” For more information about the Arduino UNO R4 check ...

Uploading to Arduino. Like in the Arduino IDE, PlatformIO allows you to either Build or Build and Upload your Arduino program to your board. In the blue bar under Visual Studio Code, you should see a ...

The Arduino Uno R3 has a special removable MCU chip. This way, you can replace that part once it’s either broken or worn down. Other boards have their MCU chips soldered to the board itself. The ...

While Arduino's language is structured on a basic version of C++, it also provides an easy syntax for beginners. Because C++ is one of the most-used programming languages, it won't be difficult to ...

The Arduino UNO R4, released in two versions last year, supports the CAN bus in terms of hardware and software. In this article we look at some handy CAN modules, an experimental setup, and the basics ...

Both the Arduino Nano and Uno can be powered via their integrated USB connectors. This automatically supplies regulated 5V power to the board, allowing you to use any USB-supported power source ...
