See as the following figure, this is a music fancy lantern controller circuit. The controller consists of sound/power switch and amplifier circuit, clock pulse generator, counting circuit and control circuit, etc. The microphone MIC switch sound signal into power signal, and then the signal is added to 4-channel analog switch CD4066(IC3) after it has been magnified by BG1~BG3. The clock pulse generator consists of IC1(555), W1, R1, R2, D1, C1 and so on, the period of signal generating is T=0.693(Rw1+R1+R2)C1, the period corresponding to the figured parameter ranges 0.5~5s, of which the 3-pin output of 555 is added to IC2 as the CP pulse.
