WT8089 based automatic 16 pattern lantern with eight music controller circuit

Circuit as shown. WT8089 is at the core circuit, it is beautiful electronic music playing at the same time, can produce 16 different patterns of jumps. The circuit consists of the clock pulse generator and pulse shaping circuits beat issued MODE side of the automatic control, control in Four Lantern automatic cycle and jump. Quad 2 input NAND gate integrated circuit CD4011 F1, F2 and RC elements form a low frequency pulse generator, door F3, F4 are connected to form a RS flip-flop, the waveform of the oscillator is trimmed to issue to become the standard The square wave signal, and then added to the IC2 of the MODE terminal (7 feet), to achieve control of the lantern automatically controlled. RC oscillator, the oscillation period:

Icon parameter oscillation period in the range of 4 ~ 16s adjustable. RP1 regulation changes to 16 kinds of lights and the rhythm of electronic music in harmony, beat, and musical flash complement each other, audio-visual effect is good.
