What is A Library.

Arduino Libraries

Libraries are files written in Cor C++ (.c, .cpp) which provide your sketches with extra functionality (e.g. the ability to control an LED matrix, or read an encoder, etc.). They were introduced in Arduino 0004.


To use an existing library in a sketch simply go to the Sketch menu, choose "Import Library", and pick from the libraries available. This will insert an #include statement at the top of the sketch for each header (.h) file in the library's folder. These statements make the public functions and constants defined by the library available to your sketch. They also signal the Arduino environment to link that library's code with your sketch when it is compiled or uploaded.


User-created libraries as of version 0017 go in a subdirectory of your default sketch directory. For example, on OSX, thenew directory would be ~/Documents/Arduino/libraries/. On Windows, it would be My Documents\Arduino\libraries\. To add your own library, create a new directory in the libraries directory with the name of your library. The folder should contain a C or C++ file with your code and a header file with your function and variable declarations. It will then appear in the Sketch | Import Library menu in the Arduino IDE.


Note: for users of versions previous to 0017, libraries belong in a subdirectory of the Arduino application directory: ARDUINO/lib/targets/libraries. For version 0017, the libraries directory was moved to make them more convenient to install and use.


Because libraries are uploaded to the board with your sketch, they increase the amount of space used by the ATmega8 on the board. See the FAQ for an explanation of various memory limitations and tips on reducing program size. If a sketch no longer needs a library, simply delete its #include statements from the top of your code. This will stop the Arduino IDE from linking the library with your sketch and decrease the amount of space used on the Arduino board.


To get started writing libraries, download this test library. It should provide a basic template for creating a new library. After you've made changes to your library, in order to get it to recompile, you will have to delete the .o file generated in the library's directory.

About this course

Have you ever needed to alter or automate a task using an Arduino? Yes? Well, have you ever needed to simplify the code needed for that task into a neat collection of easy-to-use functions? Move to the next level of Professional Arduino Programming by Automating and Simplifying tasks using an Arduino.


Then this course is for you! You will learn to make a library to initialize and control a small Arduino-powered circuit.


What You Will Learn:


  • What is a library
  • How to Write Your Own Arduino Library
  • How To Add a Library to Your Arduino Project
  • Take Arduino Programming to the Next Level with a Step by Step Guide on How to Build your very own Arduino Library from Scratch.


Why You Should Take This Course:


  • This course will teach you how to use Arduino's Sketch Editor, which is the IDE (integrated development environment) used to program Arduino boards running this version of the Arduino Software.
  • Learn to manage your code with Arduino Libraries to automate tasks and simplify coding.
  • Build your own code library for commonly used sketches including digital pin control, analog input control, PWM timer control, and more.
  • Save time programming by automating tasks with libraries for Serial Communication Control, SD Card Control, LCD Control, Analog Input Control, Digital Pin Control.
  • Gain a deeper understanding of the Arduino programming language.


Welcome to This Course:

You will learn the actual working principle of Libraries and start coding your own libraries. You will also learn what you can do with them and how to use them to improve your own Arduino coding style. Libraries are files written in C or C++ (.c, .cpp) that provide your sketches with extra functionality (e.g. the ability to control an LED matrix, or read an encoder, etc.).


I'm sure that this course will take your Arduino Projects to the next level and open your mind to new possibilities.
