Simple Buzzer Circuit Diagram using IC Timer 555
Simple Electronic Applications November 28th, 2009This 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 multi-vibrator 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.There are many variation on electronic applications using 555 timer IC.
