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.

An alternative to the Arduino IDE is Eclipse, a development environment used by professional and hobby developers. It’s open-source software and extensible via plugins.

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.

Click Sketch > Verify / Compile to make sure the code is properly in there. Save the file and then attach the Arduino to your computer with the USB cable. Click File > Upload.

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.

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.

Arduino made the announcements at CES 2020, the big tech trade show in Las Vegas this week. Millions of users and thousands of companies worldwide already use Arduino as an innovation platform.
