Lesson 9: Passive buzzer
With the Mega2560 many interactive projects are possible. The previous
projects have mainly dealt with LEDs, but a frequently used project is the
acoustic-optical display. For this a passive buzzer is used, which, in
contrast to the active buzzer, cannot activate itself.
The activation is done by a pulse frequency. Dierent frequencies result
in dierent tones of the buzzer. This can be used, for example, to repro-
duce the melody of a song.
