Arduboy Library

Deprecation Notice

This library is no longer being maintained.

It is recommended that new development use the Arduboy2 Library.

Welcome to Arduboy! This README will provide an introduction to the Arduboy platform and the Arduboy Library.

About Arduboy

Arduboy is an open-source hardware platform allowing gamers to easily make and share games using C/C++. The Arduboy Library is an open-source library that provides a programming interface for making games and applications that run on an Arduboy. The Arduboy Library supports both the production and development Arduboy units.


The Arduboy Library is on Github at

The Arduboy project is free and open-source, and is developed by the community using git and Github.

Using the Arduboy Library

To start using the Arduboy Library in your applications, the library must be available to your own project's source. The most reliable method for including the latest stable release of the Aruboy Library in your project is to use the Arduino IDE and its Library Manager.

After the Arduboy Library is installed, it must be included for use in your project's source.

Installing the Arduboy Library

The Arduboy Library can be installed on your system in manys: through the Arduino IDE, using git to clone the library, or manually download and install the library. This section outlines the most common methods, and the Arduboy Library must only be installed once. Please use the first method Install Using the Arduino IDE if you are unsure.

Install Using the Arduino IDE

Using the Arudino IDE, under the menu item, Sketch > Include Library, can be found Manage Libraries.... This will open the Arudino IDE's Library Manager. Using this dialog the Arduboy Library can be searched for and installed. After the Arduboy Library has been installed by the Arduino IDE, the library is available to all of your projects and can be included by adding, #include <Arduboy.h>, to beginning of your project's main source file.

See the section Include the Arduboy Library below for instructions on including the Arduboy Library in your own projects.

Manually Installing

Install the library by cloning the Arduboy repository.

$ git clone

The Arduboy Library can also be installed by downloading and unpacking a release package into your system's Arduino libraries folder.

Locating The Arduino libraries/ Folder

The library should be installed into your user's home Arduino libraries directory. Refer to the following list for the location of the Arduino libraries folder.

Arduino Library Locations by OS

Arduino library locations listed by operating system (OS).






C:\Users\username\My Documents\Arduino\libraries

Use the Arduino IDE to Find or Change the Location of libraries/

If you don't find the libraries folder in one of the above locations, you can determine its location using the navigation menu File > Preferences. In the Settings tab will be a Sketchbook location: field. The libraries folder will be in the folder set in this field.

Include the Arduboy Library

To start using the Arduboy library in your own sketches, the Arduboy.h header must be included in your project. To do so, add the following line to the top of your project's .ino file, or your main source file.

#include "Arduboy.h"

You can have the Arduino IDE add #include "Arduboy.h" to your sketch automatically by using the navigation menu Sketch > Include Library > Arduboy.

Using the Arduboy Hardware

The recommended way to upload to an Arduboy is by using the Arudino IDE.

Board Selection: Leonardo

Select the Leonardo board as the target platform, or use the following instructions to add the Arduboy and Arduboy Devkit to the Arduino IDE.

Add Arduboy Hardware to Arduino IDE

In the Arudino IDE select, File > Preferences. In the Settings tab there will be a field titled Additional Boards Manager URLs:, put the following in this field:

See this guide for more detailed instructions.

Arduboy Examples

Example games and source can be found in the examples directory.

Playing Examples

Find and play an example by opening it through the Arduino IDE, compiling, and uploading the example to the Arduboy.

Examples can be found in the Arduino IDE in the navigation menu under, File > Examples > Arduboy > Example_Name.

Running on a Development Board

To run this library on a development Arduboy board, edit src/core/core.h so that #define AB_DEVKIT is uncommented and #define ARDUBOY_10 is comment out.

//#define ARDUBOY_10   //< compile for the production Arduboy v1.0
#define AB_DEVKIT    //< compile for the official dev kit

Custom Arduboy Library Source

If you find that a modified version of the Arduboy Library has been used to build a game, and you have already installed a release version of the Aruboy Library, then several options are available to allow you to compile and run the application without altering the Arduino IDE's libraries.

Use one of the following options to compile sketches that have included copies of the Aruboy Library,

Option 1

Remove the local Arduboy.cpp and Arduboy.h files and try recompiling. This will only work in some cases.

Option 2

Rename Arduboy.h to CustomArduboy.h (or a similar name) and add #include "CustomArduboy.h" to the .ino sketch file.
