metronome


Posted on Feb 7, 2014

This circuit uses the 555 timer in an Astable operating mode and generates a continuous output via Pin 3 in the form of a square wave. This is then passed through the 22 ½F electrolytic capacitor to create a smooth oscillation which then creates the `toc-toc` sound. The speed of the output is controlled by the 250K Potentiometer (VR1).
