很好用 因为本设计是交通灯的控制,所以要先了解实际交通灯的变化规律。假设一个十字路口为东西南北走向。初始状态0为东西红灯,南北红灯。然后转状态1南北绿灯通车,东西红灯。过一段时间转状态2,南北绿灯闪几次转亮黄灯,延时几秒,东西仍然红灯。再转状态3,东西绿灯通车,南北红灯。过一段时间转状态4,东西绿灯闪几次转亮黄灯,延时几秒,南北依然红灯。最后循环至状态1。 2. 双色LED是由一个红色LED管芯和一个绿色管芯封装在一起,公用负端。当红色正端加高电平,绿色正端加低电平,红灯亮;红色正端加低电平,绿色正端加高电平,绿灯亮;两端都加高电平,黄灯亮。 急救车和交通灯: 中断服务程序的关键是:1. 保护进入中断时的状态-is useful because the design is the control of traffic lights, first understand the traffic lights change. Assuming a crossroads for the east-west north-south. Initial state of things 0 red light, red light north-south. Then the state opening of a north-south green, red things. For a period of time to state 2-green flashing yellow light switch several times, a few seconds delay, things are still red. Three sub-state, opening things green, red light north-south. For a period of time to state four, several things turn green blinking yellow light, a few seconds delay, the North and the South is still red. The last cycle to a state. 2. Two-color LED is a red LED tube core and a core package of green together, the common negative side. When the red is added to I-Greenpeace-Canada is low-level,
