Circuit Project Electronic

With this circuit we can create a altered sound of siren. The oscillator IC1a-b is constituted by two gates NAND, oscillating in very low frequency. This oscillation drive the IC2, that is a electronic switch, which opens and closes in the rythm of oscillation. When closes the switch then the voltage of supply charge the [...]
