用PWM方波调节LED亮度P1.1控制LED,低电平点亮K3和K4分别接在P3.4、P3.5,按下时为低电平按K3可调暗LED,按K4可调亮LED(PWM square wave with adjustable LED brightness control P1.1 LED, low light K3 and K4 are connected to the P3.4, P3.5, when pressed by K3 adjustable low dark LED, adjustable by K4 LED light)
3、 题目:输入1842——2006年之间的十进制数。 要求: (1) 要求必须有提示信息,并独占一行。 (2) 判断是否是闰年,如果是输出“yes”,否则输出“no”。 (提示:先除100,如果除尽了再用400除如果除不尽是闰年。(如果刚才的100没有除尽则用4除,除尽则为闰年。) (3) 以二进制输出xxxx年8月29日距离1842年8月29日的月数。 (4) 以十进制输出xxxx年8月29日距离1842年8月29日的天数。 (3, the title: Enter 1842--2006 decimal number between the years. Requirements: (1) requires the existence of a message, and its own line. (2) to determine whether it is a leap year, if the output " yes" , otherwise output " no" . (Hint: first addition to the 100, except if divisible by the then 400 is a leap year if the indivisible (If you just use the 100 is not divisible by 4 except, divisible was a leap year.) (3) in the binary output xxxx August 29 from August 29, 1842 the number of months. (4) decimal output xxxx years from August 29, August 29, 1842 the number of days.)

缺水报警器 硬件 1.主控板上有2个LED灯白色插座,连接2个LED插头 2.主控板上有一个缺水报警探头插座,连接缺水测试探头 3.主控板上有一个蜂鸣器 功能 1.上电后蜂鸣器鸣叫一声,进入工作状态 2.进入工作状态后,利用探头进行自动测试,若发现没有达到一定的水量(检测端口断开),便立刻进入报警状态,红LED闪(蓝灯灭),蜂鸣器鸣叫,LED灯和蜂鸣器的鸣叫频率均为2HZ。(蜂鸣器为4khz的压电式蜂鸣器) 3.或者将探头短接,也将视为有水,则蓝灯长亮(红灯灭,蜂鸣器不叫)。 (Water alarm hardware 1 master board has two LED lights white socket, connect two LED plug 2. The main control board has a water alarm probe socket, connect the test probe is water 3 main control panel a buzzer function 1 after power buzzer sound, into the working condition (2) to enter the work state, the use of automatic test probe, if it did not reach a certain amount of water (test port off), they immediately go into alarm state, the red LED flashes (blue light), buzzer, LED lights and buzzer frequency chirping are 2HZ. (Buzzer piezoelectric buzzer for the 4khz) 3, or short the probe will also be seen as water, the long bright blue light (red light off, the buzzer is not called).)
