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.

In a previous article, we looked at connecting various kinds of Arduino hardware to your Mac. Here's how to get started programming on them to create your own projects.

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.

Having easily parsed code reduces your cognitive load and makes solving problems easier. To try and help with this, [PTS93] developed the Stator library to make certain common tasks simpler to read.

The code to do this project, Richardson says, was “really easy.” In fact, it was a mashup between two projects he found using Arduino code.

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 ...

With this simple project, which requires only about $40 and one hour, you could build your own EMI detector and start using it to save on your energy bills.

In addition to using Wiring, the same application framework used by Arduino "sketches," developers can write code for Electron in C, C++, or ARM assembly code to get closer to the metal.
