这是一个三色灯变换花色，并且大部分是渐变（慢慢变亮与变暗），并且需要几十个这种IC组成一幅大图时，需要几十个IC同步工作，此程序采用了220交流电50HZ的过零同步来实现。-This is a tri-color light color transform, and most of Gradient (slowly brighten and dim), and the need for dozens of such a larger IC components, the need to synchronize the work of dozens of IC, the use of this procedure 220 zero crossing of AC 50HZ to achieve synchronization.
