Two sirens sound with ic 555

Posted on Feb 4, 2014

Operation of the circuit. Circuit is divided into three parts: low frequency production. The manufacturing high frequency and extension of production low frequency is obtained from IC1 connected to astable multi vibrator circuit frequency is set by R1, C2 frequencies that are coming out of pin 3 is about 1 Hz through R2 to be good 5. of IC2, a div

ision produce high-frequency input at Pin 5 will tone the origin of oscillator IC2 is the ripple of voltage from the output of IC1 frequency of IC2 is being set by R3, C3, which, if C3 value. will be very low tone if C3 is less treble The output will have to stand out in three legs of IC2 to stimulate B of Q1 to amplify signals that drive speakers.
