倒计时倒计时板，可以实现倒计时主题修改，时间设置等功能(dajishi)

走马灯，包括原理图和源程序，功能齐全，运用单片机开发的代码(Lantern, including schematics and source, fully functional, use microcontroller development code)

超声波测距，可以通过串口助手显示，当小于设定值时，显示0，当大于设定值时，显示1(Ultrasonic Ranging, through serial aides showed that when less than the set value, 0, when greater than the set value, indicating a)

定时器：设定时间格式（00：:00）后，到时间弹出提示(timer：set time(00:00),then run up)

用89C51单片机控制的直流电机C语言程序，程序简单有中文解释！(89C51 microcontroller with the control of DC motor C language program, the program simple to explain in Chinese!)

这是我做的一款3路LED的RGB控制器，输出接光耦控制可控硅，被控灯具为AC220V的，外接315M接受模块，用市场上一般的PT2262型遥控器无线调节输出的模式和变化速度(This is the RGB controller I do a 3 channel LED, output optocoupler control thyristor controlled lamp, AC220V, external 315M receiving module, general use on the market PT2262 remote wireless control output pattern and speed of change)

使用单片机进行智能小车寻迹控制，使用左右两个传感器。(Using microcontroller smart car tracking control, using about two sensors.)

单片机常用芯片手册,非常实用,初学者适合(Commonly used single-chip chip manual, very practical, suitable for beginners)

使用51单片机以及红外管，这段代码实现小车沿着黑色线路准确行走，但是要自己修改到合适的左右轮速度才能完美转弯。(By using 51 MCU and IR LED light tube, the code can achieve the goal of moving according to the black line. But you need revise the speed data of the left and right tire so that the car can turn aroud perfectly. )
