Desktop Buzzer

Performance by MTV

A buzzer with a red LED, controlled by a mouse.  It is the first time I use such a buzzer. The sound turned out to be terribly annoying. Unfortunately, I cannot think of a function other than bullying colleagues with it. Nasty sound. On the other hand, technically it has been reasonably successful, especially the fade-out effect on both the buzzer and the LED. I achieved this by including a capacitor in the electrical diagram.
