You can change the code so that instead of printing a message, it performs some other action. You could for example have it control LED flashing, by combining the code and hardware from this tutorial with that of http://learn.adafruit.com/blinking-an-led-with-beaglebone-black

The same setup can be used for any size button and switch!
