16X16LED汉字显示实验,移动显示“欢迎使用”(16X16LED Chinese display experiment, the mobile displays " Welcome" )
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)
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).)
