Illumination Controller (32)

Published:2011/7/7 6:55:00 Author:Sue | Keyword: Illumination, Controller | From:SeekIC

The 220v ac voltage will provide IC and audio amplier circuit with 5v direct current voltage after it is ruduced by C1, stablized by VS, rectificated by VD2, filtrated by C2,R2,C3. After IC begins to work, it's pin 10-13(L1-L4 terminals) will output trigger control signals. By controlling the working states of VT1-VT4, illumination effects of illuminations HL1-HL4 will be controlled. At the same time, IC's pin 9 will output musical signals which will drive BL to make music after it is amplified by V1,V2. S is the control button which controls illumination effects and volume. When S is pushed, the illumination effects and BL's volume will change.
