说明：  简单的流水灯控制和外部中断程序和键盘指针的应用(Simple light control and external interrupt water program and the application of the keyboard pointer)

STM32F103C8T6超声波测距报警 OLED显示(Ultrasonic ranging alarm)

步进电机控制程序，可以实现加速 减速 匀速，里面包含两个程序(Stepper motor control program, you can achieve a uniform acceleration and deceleration, which contains two procedures)

说明：  24C08多花样流水，采用51开发板，编程使LED呈流水灯，初学者的好例子。(24C08 multi-pattern, running water, with 51 development board, program the LED lights were water, a good example for beginners.)

以监控和控制为目的的算法因为其数据要在数据中心汇总和处理，大多使用集中式算法，其精度较高，但通信量大。分布式算法是传感器节点在采集周围节点的信息后，在其自身的后台执行定位算法，该方法可以降低网络通信量，但目前节点的能量，计算能力及存储能力有限，复杂的算法难以在实际平台中实现(To monitor and control algorithms for the purpose because of its data to be aggregated and processed in the data center, mostly using centralized algorithm, its high accuracy, but the communication volume. Distributed algorithm is the information collected in the sensor nodes around node positioning algorithm executed in its own background, the method can reduce network traffic, the limited energy of the current node, computing power and storage capacity, the actual complex algorithms difficult platform to achieve)
