- 
-When using the sample code, the library files need to be placed in the same folder. (As shown below）

-=== sample code === 
-<code> 
- 
-''/*! 
- * WMNologo 
- * 矩阵键盘 
- * 
- */ 
-#include "Matrix_buttons.h" 
-// 创建对象 
-Matrix_buttons Matrix_buttons1; 
- 
-// 主程序开始 
-void setup() { 
-  Serial.begin(9600); 
-} 
-void loop() { 
-//S信号线接入A0 
-  Serial.println(Matrix_buttons1.get_follow_sensor(A0)); 
-} 
-'' 
- 
-</code> 
- 
-=== result === 
- 
-The serial port prints the value corresponding to the matrix keyboard
