数码管静态显示源代码，可以直接调入工程使用(Static digital tube display the source code can be directly transferred to the engineering use)

使用51单片机和cc2530模块组成的路由器程序，可以实现收发和存储功能(51 machines use a single product and get the router module cc2530 program)

ESP8266制作的安卓控制电风扇，内含详细电路即软件。手机APP使用非常简单。智能家居等设备控制均可类似实现(ESP8266 Android-controlled fan, fan after simple modification can be realized, containing detailed circuit software.Mobile APP is very simple.Smart home control can be similar to achieve)

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. )

自动交通控制系统用红、绿、黄三支共两组发光二极管表示交通信号灯，利用单片机模拟有时间显示的定时交通信号灯控制管理。信号灯的变化规律可如下： 1）放行线：绿灯亮放行25秒，黄灯亮警告5秒，然后红灯亮禁止。 2）禁示线：红灯亮禁止30秒，然后绿灯亮放行。 3）当某一方向的红灯亮时，若该方向有车通过，则用扬声器声报警。（撞红灯信号可用3-5V模拟量表示）(Automatic traffic control system using red, green, yellow light-emitting diodes, said a total of three traffic lights, the use of single-chip analog time display on a regular traffic signal control and management. Changes of lights to be as follows: 1) Release Line: green clearance 25 seconds, the yellow light warning for 5 seconds, then the red light is prohibited. 2) ban shows lines: the red light is prohibited for 30 seconds, then the green light to release. 3) When the red light in one direction, if the direction of the car through, the alarm speaker sound. (Hit the red signal available 3-5V analog representation))
