This interests me because I started out in Electrical engineering school in college. I'm intrigued by raspberry pi. I bet you would find specific answers reading about how the hardware works. Does Raspberry pi come with push buttons that are connected to some io ports or a usb port or a keyboard or? If there is no physical switch, one of the gui frameworks for python certainly will have hooks to invoke code when a (virtual) button is pressed. Maybe find a Raspberry pi newsgroup? > > -- > Antoon Pardon > > > > -- > https://mail.python.org/mailman/listinfo/python-list -- Joel Goldstick http://joelgoldstick.com
