A simple electronic buzzer
This very simple circuit just uses a couple of resistors, a capacitor and the
easily available 555 timer IC.
The 555 is setup as an astable multivibrator operating at a frequency of about
1kHz that produces a shrill noise when switched on. The frequency can be changed
by varying the 10K resistor.
