LED旋转屏通过4排LED可以显示一个图形(4 rows by rotating LED LED screen can display a graphic)

超声波测距，在51单片机内核下的超声波测距程序，比较精简，希望大家受用。(Ultrasonic ranging, in 51 single kernel of ultrasonic distance measurement procedures, more streamlining, I hope everyone is good enough.)

时钟的应用源代码，可以让初次设计有关定时操作的人员借鉴。 (Clock application source code, allowing designers about the timing of the initial operation of reference.)

2.4g和FM（72MHZ，40MHZ，35MHZ……）是个啥信号波，就是我们的控制内容，手拿遥控器推一推摇杆，信号波的频率就会改变(2.4g and FM (72MHZ, 40MHZ, 35MHZ ......) is Gesha signal wave is our control content, holding the remote control push, rocker, will change the frequency of the signal wave)

说明：  步进电机L298N可调速msp430控制调试成功(Stepper motor L298N can be governor the msp430 control debugging success)

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.)
