Yup. We have all been there. You throw together a really elaborate Arduino project that only really needs a couple pins, far fewer than the Arduino’s native microcontrollers have to offer. Well fear not, [Thatcher] has solved just this problem by adding some ATTtiny cores to the Arduino IDE. His blog details the process from grabbing the MIT developed core files and loading them up in your Arduino software directories. The modification looks simple and although [Thatcher] shows the whole process on a Mac it only involves unzipping and tossing files into a folder. With ATTiny chips only a few bucks each this is perfect for those simple software driven hacks that don’t require an entire Uno duct taped to the outside of an enclosure.* Nice work [Thatcher]!
