Police Siren Circuit on Breadboard | 555 Timer Project #14

A tutorial on how to make a police siren circuit using 555 timer IC and a few other electronics components. This circuit smoothly transitions the output sound between two different tones/frequencies, similar to the sound emitted from police cars.
Explanation of how this circuit works is also included in the video
