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.

If there are any problems please contact webmaster@electronic-circuits-diagrams.com
