1.Schema electrica a circuitului

2. Descrierea circuitului – Sirena de politie

Circuitul produce un sunet similar unei sirene de politie, utilizand doua circuite

555.

555 este un circuit integrat, folosit intr-o mare varietate de aplicatii cu timere,

generatoare de puls si oscilatoare. A fost creat in 1970 de Hans R Camenzind si

comercializat in 1971 de Signetics (acum NXP Semiconductors). Aceasta

componenta este folosita si astazi deoarece este usor de utilizat, are un pret

scazut si este stabil.Peste un milliard de unitati sunt fabricate anual.

Circuitul foloseste doua timere 555 pentru a produce un sunet ce oscileaza.

Variatia voltajului aplicat pinului 5 produce modificarea frecventei celui de al

doilea oscillator: creste sau scade.

Iesirea primului 555 este conectat la pinul 5 al celui de al doilea 555, controland

voltajul aplicat. Astfel, semnalul de iesire al celui de al doilea 555 este modulat de

frecventa primului 555, provocand efectul de sirena. Variatia voltajului aplicat

pinului 5 produce modificarea frecventei celui de al doilea oscillator.

Pe scurt, frecventa semnalului ce iese din cel de al doilea 555 este controlata de

iesirea primului 555.

555 are trei moduri de functionare:

- Modul Monostabil : functioneaza ca un generator

de puls

- Modul Astabil : functioneaza ca un oscillator

- Modul Bistabil sau Trigger Schmidt

In acest circuit 555 functioneaza in modul astabil, astfel ca, 555 genereaza un flux

continuu de impulsuri dreptunghiulare avand o anumita

frecventa.

Rezistorul R1, R2 si condensatorul C1 permit utilizarea in modul astabil, 555

comportandu-se ca un oscillator. In modul astabil, frecvența curentului de puls

depinde de valorile lui R1, R2 și C:

f=

( ) ( )

Aplicand o tensiune la pinul CTRL ( Voltage Control) se pot modifica

carecteristicile de sincronizare ale dispozitivului. In cele mai multe aplicatii pinul

CTRL nu este utilizat. De obicei, se conecteaza un condensator de 10nF intre

acesta si masa, pentru a preveni interferentele.

Condensatorul electrolitic conectat in serie cu difuzorul are rolul de a bloca

component continua, prevenind astfel defectarea bobinei difuzorului.

Circuitul poate fi alimentat la tensiuni cuprinse intre 5 – 15 V.
