What is this mod? This mod is a revamp of Simpit, a mod initially created by Stibbons . This mod enables KSP to connect to an Arduino (using the companion Arduino lib) to exchange data between KSP and Arduino. This allows for the creation of custom controllers.   Installation from CKAN (should be available shortly) If you want to install it manually, download here from here and follow the instructions from the README.
