LM386 making music with a voice-activated lights circuit


Posted on Mar 28, 2007

VD1, VD2, C1 and C2 form a simple half-wave rectifier capacitor step-down voltage regulator circuit, the output of about 12V in straight right current voltage supply manifold LM386 electricity.

LM386 connected to the inverting input terminal 3 feet inside the piezoelectric ceramic sheet B receiving environment acoustic signal and converts it into a corresponding electrical signal, amplifying circuit after the internal manifold by 5 feet output by C4, T bidirectional drive thyristor vs, make vs conduction angle B with signals picked up strength and change, so can make the lantern string H with flashing light and acoustic environment signal strength.
