51单片机RC522读写卡程序（充值消费功能）

以一个m×n的长方阵表示迷宫，0和1分别表示迷宫中的通路和障碍。设计一个程序，对任意设定的迷宫，求出一条从入口到出口的通路，或得出没有通路的结论。首先用二维数组存储迷宫数据，迷宫数据由用户输入。一个以链表作存储结构的栈类型，然后编写一个求解迷宫的递归或非递归程序。求得的通路以三元组（i，j，d）形式输出，其中：（i，j）指示迷宫中的一个坐标，d表示走到下一坐标的方向（东、南、西、北四个方向所用代表数字，自行定义） (With an m × n the long square maze, 0 and 1, respectively maze of pathways and obstacles. Design a program, for any set of the maze, find a path from the inlet to the outlet, or come to the conclusion there is no path. First of a two-dimensional array to store the data maze, maze data input by the user. A linked list storage structure for stack type, and then write a recursive or non-recursive solving the maze procedure. Obtained access to triples (i, j, d) in the form of output, of which: (i, j) indicates the maze of a coordinate, d represents the coordinates walked next direction (east, south, west, north four directions used on behalf of a digital, self-defined))

本例子涉及到arduino与物联网的连接，包括arduino控制SIM与物联网的连接，使用SIM900A模块，使用GPRS流量包发送数据，使用超声波模块发送数据，利用到了发送函数，可以自动监测超声波传感器的数据，并且上传到网络。
