Hello Arduino Forums! For whoever is looking at this, I need help with library installation. I am new to Arduino and don't know how to do it. I am working on a science fair project and need this library: Arduino Playground - HomePage, to do part of the experiment. I have no idea how to set it up. I have also heard about the header and source files, but there aren't any actual files that I can put on my Arduino. Any help would be appreciated.
