关于Arduino UNO软复位后的问题提问

对于Arduino，可以用

void(* resetFunc)(void) = 0;
......
resetFunc();

进行软复位。

但是，本人的UNO进行过这一操作后出现异常复位的现象。

laser.h如下：

#include "Arduino.h"
#include 
#include 
#define pi 3.14
#define ir1 16738455
#define ir2 16750695
#define ir3 16756815
#define ir4 16724175
#define ir5 16718055
#define ir6 16743045
#define ir7 16716015
#define ir8 16726215
