Software for Witty Pi

Witty Pi needs software supports to activate all functionality. We write these software as bash scripts, which are very easy to be customized.
In the bash scripts, we use the GPIO utility from wiringPi to interact with the GPIO pins. It is possible to replace this utility with another one if you want.
All the bash scripts, including the installing script can be found in Github: https://github.com/shawnu/Witty-Pi
