Illumination Controller (31)

Published:2011/7/7 6:14:00 Author:Sue | Keyword: Illumination, Controller | From:SeekIC

The 220v ac voltage will provide IC with 4.5v direct current working voltage after it is rectificated by VD1-VD4, limited and reduced by R1, stablized by VS, filtrated by C1. After IC begins to work, its pin 1-4 will output trigger control signals. By controlling the working states of VT1-VW, illumination modes of the illuminations will be changed according to actual requirement. At the same time, IC's inside musical circuit will drive HA to make music directly. S is the button which controls illumination modes choice and volume. When S is pushed, the illumination modes are changed and HA's volume is changed.
