From what I understand... A buzzer that can be activated by a computer... like a electronic school bell that is triggered by a computer. You can do two things, 1. know micro-controller technology, computer interface, programming, and GUI creation. 2. Use the parallel/serial port and connect it directly to the buzzer and programming for the GUI/interface. (don't know if option 2 will work)
