Simple Siren Circuit
This schema will generate siren sound when S1 pressed and increate sound frequency becuase
capacitor C1 charged when switch S1 released the frequency will decreated(C1 discharged).
Try to change resistor R3 if you need to change time interval from low to high frequency and vise versa.Link
