急救车与交通灯）（1）南北与东西方向，每个方面由红黄绿三个灯控制（2）南北向：　红（30秒），黄（5秒），绿（25秒）　　　东西向： 红（35秒），黄（5秒），绿（25秒）　　　上述基本参数可以根据实际情况自行调整，灯的变化规律与实际路口规律相同，绿灯在最后5秒钟时，黄灯亮，然后红灯亮，不允许两个方面同时亮绿灯。（3）绿灯的时间显示在数码管上进行显示。（4）可以通过一个开关控制，当开关信号为0时，整个交通灯全灭提高要求：（1）设计一个紧急控制开关信号，当紧急开关信号为1时，两个方向的灯全为红灯。紧急开关撤消后，按照开关按下之前的状态继续运行（其参数要保存）。（2）设计一个夜间行车开关，当开关按下后，两个方向都只有黄灯闪烁，其它灯熄灭。（3）设计两个方向的亮时时间可调。-emergency vehicles and traffic lights) (1) North and South and east-west direction, each with three yellow-green from red lights control (2) to the north and south : red (30 seconds), yellow (5 seconds), Green (25 seconds) to things : red (35 seconds), yellow (5 seconds) Green (25 seconds) above basic parameters can be adjusted to the actual situation, the light changes with the actual law of the same intersection, the green light in the final five seconds, the yellow light is on, and then a red light, bright, not two fronts simultaneously bright green. (3) the green light at the time displayed on the digital display control. (4) can be controlled by a

基于51单片机和ad9850实现的信号发生器程序实现输出1k-1m步进可调-51 Based on the AD9850 single-chip computer and realize the signal generator output procedures realize adjustable stepper 1k-1m

由于输出的是方波，比较难听:-) 只能说是非常难听:-)为什么呢？只因为输出的是方波,包含了大量的奇次谐波。 你可以用双龙的"虚拟仪器"分别产生正弦波、三角波和方波听一下，正弦波感 觉就比较纯正，而方波则要多难听有多难听！-As the output is a square wave, more bluntly :-) can only say that it is very nasty :-) Why? Simply because the output is square wave, including a large number of odd harmonics. You can use Shuanglong

这是一个红外报警系统，该系统通过555调制红个发光管，发出38KHZ的红外信号，对面使用一个红外接收头接收信号用来检测是否有人通过，如果有，则声光报警，-This is an infrared alarm system, which modulator 555 through a red light-emitting tube, issued 38KHZ IR signal, opposite to the first use of an infrared receiver to receive signals to detect whether or not it was passed, if so, make a sound light alarm,
