Official Arduino Example Tutorials: The Arduino computer software is loaded with tons of examples for you to use in your own code or to run through as a learning experience.

The Arduino microcontroller takes over from there and executes your code on the Arduino. During upload, if your Arduino has an RX (Receive) LED built-in, you should see it flash rapidly as it ...

Arduino is designed to allow you to execute code without all the fuss of dealing with an operating system. And since it does one thing and only one thing at a time, it’s really, really easy to use.

Arduino lends itself very well to a hands-on learning style, so pick up some basic equipment, work through a few tutorials, and then tackle some fun beginner projects. To get started, you will need: ...

That provides a professional development environment, at least. The code base for the Arduino is another frustration. Bluntly, the use of setup() and loop() with main() being hidden really bugs me.

Once you learn how to read Morse code, you might want to teach your Arduino to understand it, too. Or, you can check out some other Morse-based projects.

And if you've worked in ROS1, Renard will show you how to turn those projects into ROS2 code with minimal frustration. Raspberry Pi and Arduino are amazing on their own, but intimidating to learn.

If, however, they don't seem to be a great fit for your needs, there are several other small Arduino boards you can use instead, including the Micro (18 by 48 mm), MKR Zero (25 x 61.5 mm) and MKR ...
