A noter : si l'on se contente d'un niveau sonore faible, il est parfaitement possible de brancher un buzzer électromagnétique passif directement sur une sortie de l'ARDUINO en intercalant une résistance adaptée, 100Ω par exemple. The siren is produced by increasing a tone frequency from 440 Hertz to 1000 Hertz and then decreased back to 440 Hertz again with a 5 millisecond delay between increments.
