Usually it’s inside the “My Documents/Arduino” folder, unless you changed the default location. To do that, find where your Arduino sketch is located. Let’s create 2 files: a Cpp and a header file. Separating the library code from the rest Here we’ll make the addTwoInts() function a part of a library named my_library.įor now, all the code is in the same file, which isn’t really practical for separating the library from the main code. The function will take 2 integers as parameters and return the sum. Let’s start with a very simple program, and from that create a library step by step.įirst, write this small Arduino sketch, which only has one function. Step 1: Write your Arduino library code Starting code Going further with your Arduino library.Another example: a library for a LED class.Import the library through the Arduino IDE.
Place your library files into the Arduino libraries folder.Separating the library code from the rest.Step 1: Write your Arduino library code.
