The circuit is as shown. This circuit is composed as the core of WT8089, when it is playing a pretty electronic music, it can produce 16 kinds of different parrents dance methods. MODE terminal is actumatically controlled by clock pulse generator and the rhythm pulse is sent by shaping circuit, it can make the four kinds of color lamp control methods achieve automatical cycle and jumping. A low frequency pulse generator is composed of four 2 input terminal and the gate F1, F2 of negation gates IC CD4011 and resistor capacitor component, gates F3, F4 are connected to a RS trigger, it can trowel the waveform sent by oscillator, then it will change into standard square wave singal, it is added to MODE terminal (seven foot) of IC2, it can achieve automatical cxontrol for color lamp control method. The oscillation period of RC oscillator is The oscillation period is adjusted in the range of 4~16s. To adjust RP1, it can coordinate color lamp's 16 kinds of changes and the rhythm of electronic music, good flashing jumping and feeling of music, the audio-visual effect is nice.
