Arduino IDE Limitations Editor Tabs When projects get larger they obviously have more lines of code. Having hundreds or thousands of lines of code in a single file is a nightmare.

For Arduino beginners like us, this is where you paste the code from other people's projects. When you send the code to the Arduino from your computer, the code is stored on the Arduino itself.

With all of the components ready, I begin to assemble the central motor hub and test code for the air fins. In this series, I ...

Hook the device up, upload your program, and you're done - and you can even disconnect the Arduino from the PC and hook it up to a battery and have your code running as a stand-alone device.

Programming means understanding how code interacts with actual computer hardware. If you want to get a visceral (and fun) understanding of programming, start with an Arduino.

You can see the project in operation in the video below. Once you learn how to read Morse code, you might want to teach your Arduino to understand it, too.
