交通灯控制器主要是利用了一个计数器芯片的计数，当计数器开始有稳定的秒脉冲输入时就开始计数，秒脉冲是用555多谐振荡器产生的，然后再通过各种门电路的逻辑组合实现最后的交通灯功能。-Traffic light controller is to use a counter chip count when the counter started a steady start when seconds count input pulse, second pulse is over 555 harmonic oscillator, and then again through the logic gate combination functions to achieve the final traffic light.
