Anywhere you use FALLING in your code, the number 2 will be substituted at compile time. #defines can get quite complex but can make your code shorter and more readable.

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.

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.

By harnessing the power of 3D printing, servo motors, and Arduino programming, you’ll create a robotic arm that responds to your commands through a sophisticated software interface, allowing for ...

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.
