Before you start, you'll need to follow the guide for your particular board to install the Arduino IDE, drivers and board support package so that you can upload code to it via Arduino
We use quite a number of libraries to access the display, sound, buttons, etc.
In addition to the Arcada libraries, you'll need the Adafruit-tweaked versions of all the Arduboy libraries. We will install these manually, not through the library manager, so download the Zips and then select Add .ZIP Library... to install each one
These replace the existing libraries but add support for Arcada boards, for that reason, you should remove any existing libraries you have with these names!
