Arduino Libraries
1. Download the file
2. Unzip the file using 7zip or WinRAR
3. Put all files in <arduino directory>/Libraries (*all files should reside in a folder with the same name as the library itself)
4. In Arduino compiler you can import the library into your current sketch by clicking on Sketch>Import Library>[Library Name] or view examples by clicking on File>Examples>[Library Name]>[Example] or use #include<libraryname.h> at the beginning of your code
Libraries:
SuperSerial v1.3 - effective for inputting numerical values (int & float) through USB serial communication.
Why you need it: The Serial library included with the basic Arduino installation is OK for serial output, but doing serial input is another matter. David Adams and Yoshio Tsuruta have written this serial input library which takes the pain out of doing it with the basic Arduino Serial library alone. Try it; you'll like it!
Note: An old version of the SuperSerial library (v1.2) is offered below for anyone using a version of the Arduino before 1.0
