简单的流水灯程序，另外包括按键控制led灯程序，适合初学者(Simple water lights, led lights additionally includes key control procedures, suitable for beginners)

测试电脑鼠各个红外探测器的算法，可自行调试(Test each computer mouse infrared detector algorithm, self-debugging)

智能追踪小车，并且可以用遥控手动控制转弯加前后左右(Intelligent tracking car, and can be controlled manually with the remote turn around Canada)

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.)

全自动可遥控旗帜升降系统以AVR单片机为核心，由PWM对电机进行变频调速，高精度光电编码器测速，闭环式电路控制。能够利用按键输入相应的指令控制旗帜的升降，还可以实现在特定位置停留的功能。利用LCD可以显示旗帜的实时高度和相应的控制命令，用LED指示旗帜是否处于半旗状态，具有语音提示报警功能，并可利用无线模块实现遥控功能，准确均匀地实现旗帜的升降(Automatic landing system can be remote-controlled flag to AVR microcontroller core of the PWM VVVF motor, high-precision optical encoder gun, closed-loop control circuit. Enter the appropriate button to take advantage of the command control of the rise and fall of the flag, but also can stay in the function of a specific location. LCD can display the banner of the use of real-time high and the corresponding control command, the LED is directed at the flag half-mast, and alarm functions with voice prompts, and the use of wireless remote control function module, to achieve uniform and accurate take-off and landing flag)

energy emwin驱动程序，可驱动彩屏及相关LCD控制器(energy emwin)

对ad7685的详细运用。加上12864显示。有电路图、芯片资料(Detailed use of ad7685 plus 12864 shows)
