arduino输出乱码与远程控制

最近在做项目，使用arduino控制超声波,pm2.5等传感器，以及继电器等，然后连接wifi进行远程控制

发现代码都正确 ，但是板子串口输出是乱码的情况

一一排查之后发现是超声波的trig口接在了wemos版的d9上，这是一个板子自带的led灯的控制口

超声波传感器总是发出‘滋滋’的声音，吓我一跳

最后改为了，d8,d10才解决，代码如下

#include
#define MAX_SRV_CLIENTS 1
#define dustPin A0
#define Trig  0 //引脚Tring 连接 IO D8
#define Echo 15 //引脚Echo 连接 IO D10
int flower_led=5;//d3
int led_led=4;//d4
int door_led=14;//d5
int power_led=12;//d6
int curatin_led=13;//d7

float dustVal=0;
int ledPower=16;//d2
int delayTime=280;
int delayTime2=40;
float offTime=9680;
float cm; //距离变量
float temp; //



//连接 AP 的账号
const char* ssid = "Tenda_3BFE70";
//连接用的密码
const char* password = "lizhendewifi";
