The music lantern control circuit shown in Figure 7-31 is mainly composed of a program-controlled lantern integrated block SH816. It can be used to play 25-tone two-tone, high-quality piano music songs, through the chip 10 feet, 11-pin main and secondary output, to promote 32-ohm speaker playback. And drive the 4-way lantern string to make it flash with the beat of the music. There are 4 kinds of patterns and 8 patterns of flashing patterns. Each time a song is played, a pattern is changed, one cycle.
Circuit principle: SH816 is a large-scale CMOS music lantern flash control dedicated IC, using a chip-shaped vinyl package, there are 15 external lead, 2 of which are above the IC chip, a total of 75K ohms of resistance is directly mounted. The pin function can be seen in Table 7-12.
SH816 memory 1536 notes, 25 world famous songs, composite double sound, piano sound effects, SM816 built-in 4 plus 8 kinds of lantern pattern jump program, using double-key control, connected to the 6-leg case R is the function selection button, At the 5-pin button K1, there are 8 kinds of lamp jump mode locks, and K2 can realize 5 kinds of control functions.
