Description: 多路开关状态指示
如图4.3.1所示，AT89S51单片机的P1.0－P1.3接四个发光二极管L1－L4，P1.4－P1.7接了四个开关K1－K4，编程将开关的状态反映到发光二极管上。（开关闭合，对应的灯亮，开关断开，对应的灯灭）。
-multiple switch state instructions shown in Figure 4.3.1. AT89S51 SCM P1.0- P1.3 then four LED L1- L4, P1.4- P1.7 then switch the four K1- K4, programming will switch the state to reflect on the light-emitting diode. (Closed switch, the corresponding lights, switches off, the lights corresponding to eliminate).

Description: 假设道路交叉口，有红绿黄三色交通控制灯，且要求：
1）。绿灯亮是，车辆可潜行，过30秒，绿灯熄灭，黄灯亮；
2）。黄灯亮5秒后，熄灭，红灯亮，车辆停止前行。红灯亮30秒之后熄灭，黄灯亮；
3）黄灯亮5秒之后，熄灭，绿灯又亮，车辆可通行，如此循环。
-Assuming the road intersection, a red-green-yellow three-color traffic control lights, and requirements: 1). The green light is that vehicles will be allowed to sneak, over 30 seconds, the green light is off, yellow light 2). 5 seconds after the yellow light, off, red light, vehicles to stop before the line. 30 seconds after the red light is off, yellow light 3) 5 seconds after the yellow light, off, green light, bright, vehicles that can use it, and so the cycle.

Description: 单片机C语言教程：流水灯实验
单片机在上电初始后，其各端口输出为高电平。如果我们现在想让接在P1.0口的LED1亮，那么我们只要把P1.0口的电平变为低电平就可以了。想让LED1灭，LED0亮，只需将P1.0升高，P1.1变低，LED1就熄灭LED2随后既点亮！依始类推如下所示8只LED变会一亮一暗的做流水灯了.
P1.0低、P1.0高、P1.1低、P1.1高、P1.2低、P1.2高、P1.3低、P1.3高、P1.4低、P1.4高、P1.5低、P1.5高、P1.6低、P1.6高、P1.7低、P1.7高、返回到开始、程序结束。-SCM C Language Tutorial: water light test of SCM in the initial power-on, its output is high the port. If we now want to take the P1.0 port of LED1 light, then we as long as the P1.0 port into a low level on it. LED1 want to eliminate, LED0 bright, just P1.0 increased, P1.1 goes low, LED1 to LED2 followed by both the light off! Only by analogy as follows in accordance with 8 LED change will be a light to do a dark light of the flowing water. P1.0 low, P1.0 high, P1.1 low, P1.1 high, P1.2 low, P1.2 high, P1.3 low, P1.3 high, P1.4 low, P1.4 high, P1.5 low, P1.5 high, P1.6 low, P1.6 high, P1.7 low, P1.7 high, Return to the beginning, the program ended.

Description: This circuit automatically turns on a
night lamp when bedroom light is
switched off. The lamp remains
‘on’ until the light sensor senses daylight
in the morning. A super-bright white
LED is used as the night lamp. It gives
bright and cool light in the room. When
the sensor detects the daylight in the
morning, a melodious morning alarm
sounds.

Description: 某交通管理部门要求，交通灯要求主干道绿灯至少保持2分钟（其中不包括绿灯闪烁时间），在此前提下，当支路检测到有车或人时，主干道绿灯闪烁3秒，然后黄灯持续亮3秒，红灯再亮，同时支路绿灯亮，红灯灭。当支路连续5秒检测不到车和人时，支路绿灯闪烁3秒，然后黄灯持续亮3秒，红灯再亮，同时主干道绿灯亮，红灯灭，支路绿灯最长持续20秒（不包括绿灯闪烁时间）。若从绿灯闪烁开始禁止支路上行人和车辆通行，则可保证主干道禁止通行的最长时间为26秒。支路可通过仪器来检测有无车辆和行人，对于行人，由于其不定性，需要设置一些仪器，如果有行人想通过，需站在其中一个检测仪下，当任一仪器检测到有车辆和行人要横穿主干道时，发出信号。由于主干道禁止通行的时间至多为26秒，因此，无需检测有无车辆和行人。-
Requirements of a traffic management department, asked the main road traffic lights green for at least 2 minutes (not including the green light flashes the time), in this context, when the slip road vehicle or person is detected, the main road the green light flashes for 3 seconds, then yellow lamp is lit for 3 seconds, then red light, green light at the same time slip, red light off. When the slip is not detected continuously for 5 seconds when the cars and people, slip the green light flashes for 3 seconds, and then the yellow light is lit for 3 seconds, then red light, green light while the main road, the red light off, the longest continuous green slip 20 seconds (not including the green flashing light). If the green light flashes from a ban on pedestrian and vehicle traffic support on the road, you can ensure that the maximum time the main road closed to traffic for 26 seconds.
