There aren't enough libraries available for makers to integrate bitcoin in their projects or connect to different blockchains. This library is a WIP, Our team is targeting the maker community or anyone interested in building prototypes for products that harness the blockchain technology or want to monetize some function/usage of their HW project.
We made a debut DIY vending machine using the library and it worked perfectly
Tutorial Here : http://bit.ly/ArduinoBitcoinMachine
We can think of a plethora of use cases for such project and the potential is big, especially for makers or developers who are not that involved in the blockchain technology but want to provide digital currency/ blockchain integrations in their projects as the code is beginner-friendly.
You can find the link to the library here: http://bit.ly/koynLibrary
Please let us know what you think. and if you have any ideas or projects that can be implemented using the library share with the community here.
