SH805 based dual-purpose lantern power control circuit with music

Circuit shown in the figure, which consists of voice switches, light control switch, one-shot timing circuits, control circuits and music sound lights circuit. The light control circuit 16 functions procedures, can automatically transform, colorful, and its control is the sound, light double control, the day will not be lit at night only for voice. In the lights flashing, it is also accompanied by sweet waltz music.
