(The Fabulous) Matt Wayland has produced a guide for the conversion of Arduino libraries to external libraries that can be used in XOD. The guide has been collated and formatted by Steph Norwood at Biomaker, Cambridge - and is available freely as a PDF (16 pages, 19 MB) to download from:

(Linked with the title: ‘Converting Arduino Libraries to XOD: Tutorial guide that takes you through how to convert (class-based) Arduino Libraries into XOD nodes. Useful for expanding the range of hardware you can use in XOD. Written by Matt Wayland’)
We hope that this is useful for others who might be thinking of adapting new hardware with existing Arduino libraries - for code-free use in XOD.
