My current understanding is that Arduino stands for a whole set of related tools designed to be used together, in order to make it easier to get into microcontroller programming. The individual bits and pieces involved are:</p> <ul> <li>Arduino development boards, such as the Uno or Leonardo, typically running AVR chips such as ATmega328P or ATmega32U4</li> <li>Arduino bootloader, a program that runs on these boards and allows reprogramming them over USB</li> <li>Arduino IDE, an app that lets you write C code and upload it to the board; it comes bundled with the compilation toolchain (avr-gcc) and an upload tool (avrdude)</li> <li>Arduino standard library, a set of C modules which makes it easier to do common tasks e.g. <code>digitalWrite()</code> or <code>Serial.write()</code></li> <li>A while ecosystem of libraries written against the Arduino standard library, eg. [ws12812B-arduino][ws12812B-arduino]</li> </ul> <p>I always wanted to learn <strong>what does Arduino IDE do under the hood?</strong> How do I program a board myself by using the underlying tools directly? Read on to see what I found out.</p> <p><a href="https://kos.gd/posts/arduino-without-arduino/">Read more…</a> (6 min remaining to read)</p></div>arduinodiyelectronicstilhttps://kos.gd/posts/arduino-without-arduino/Mon, 16 Feb 2026 00:00:00 GMT
