CRAL: An Arduino & Freeduino Library Repository

CRAL is a repository of open source *duino libraries for external devices and circuits. It is meant so that tinkerers can focus on building the business logic of their project instead of stitching everything together.

Note: "*duino" is used on this site in a none discriminating way to indicate that the libraries work on either original Arduino's or clones.
