Tweet Scale

/*
This is a processing sketch that uses twitter api to check the frequency of the occurrence of the predefined strings. In this one, we used love and hat, but you can also change them and try things like obama and bush. After, the frequencies are compared and a degree value is obtained through this comparison. this degree value is sent through serial port to arduino to change the angle of the servo motor.
you can see the example video here:
