As shown in the figure 11-29, the controller is composed of 4-step monostable timing circuit, it adopts interstage head-tail connecting to form ordinal trigger loop. After connected the power supply, only AN button is pressed, it can run. Each step's delay can be adjusted by its potentiometer. Such as the first step, its delay time td=1.1RP1C1,the max delay time, namely, the time of LED1 lighting is about 10s. The other steps are the same.
If this circuit is remodeled, then the output can control the on/off of TRIAC, and it also can control the colored lights, it can be used as dance party lighting cintroller or other time schedule controllers. The amount of cascade connection doesn't matter, it can form pursual loop or multicolour pattern.
