【求教】关于RFID控制的问题【arduino吧】

以下是我在做一个用RFID控制led灯和舵机的小玩意的程序，功能是当RFID读到ID卡时将LED灯点亮并使舵机旋转75度，过10秒钟后LED灯闪烁两下后熄灭舵机转回原位，现在我想完成让RFID在LED灯点亮时如果读到ID卡就让LED灯和舵机工作的延时重置请问该怎么改才能完成这个目的？跪求大触指导

#include <SoftwareSerial.h>
#include <Servo.h>
SoftwareSerial RFID(3,4);
Servo servo;
const byte taglen = 14;
byte temp[taglen];
String rfidStr = "";
const byte LED = 13;
String tag1="24848484852654968706765663";
String tag2="24848484852654968555250513";
String tag3="24848484852654866524948483";
boolean readTag(){
boolean ok = 0;
if (RFID.available()){
delay(1000);
for(byte i=0;i<taglen;i++){
temp[i] = RFID.read();
}
RFID.flush();
ok = 1;
}
return ok;
}
void setup(){
Serial.begin(9600);
RFID.begin(9600);
pinMode(LED,OUTPUT);
servo.attach(5);
}
void loop(){
if (readTag()) {
rfidStr="";
for (byte i=0;i<taglen;i++){
rfidStr += temp[i];
}
Serial.println(rfidStr);
if(rfidStr==tag1||rfidStr==tag2||rfidStr==tag3){
digitalWrite(LED,HIGH);
servo.write(75);
delay(10000);
digitalWrite(LED,LOW);
delay(100);
digitalWrite(LED,HIGH);
delay(100);
digitalWrite(LED,LOW);
delay(100);
digitalWrite(LED,HIGH);
delay(100);
digitalWrite(LED,LOW);
servo.write(-75);
}else {
digitalWrite(LED,LOW);
}
}
}

用delay()不能實現你的要求，要用輪詢
setup(){
old-time=milli();
}
loop(){
if(millis()-oldtime>1000){ //每一秒運作一次
//工作代碼
old-time=millis();
}
}

#include <SoftwareSerial.h>
#include <Servo.h>
SoftwareSerial RFID(3,4);
Servo servo;
const byte taglen = 14;
byte temp[taglen];
String rfidStr = "";
const byte LED = 13;
String tag1="24848484852654968706765663";
String tag2="24848484852654968555250513";
String tag3="24848484852654866524948483";
unsigned long oldtime,worktime;
boolean readTag(){
boolean ok = 0;
if (RFID.available()){
delay(1000);
for(byte i=0;i<taglen;i++){
temp[i] = RFID.read();
}
RFID.flush();
ok = 1;
}
return ok;
}
void setup(){
Serial.begin(9600);
RFID.begin(9600);
pinMode(LED,OUTPUT);
servo.attach(5);
oldtime = millis();
worktime = millis();
}
void loop(){
if (millis()-oldtime>1000)
{
if (readTag()) {
rfidStr="";
for (byte i=0;i<taglen;i++){
rfidStr += temp[i];
}
Serial.println(rfidStr);
if(rfidStr==tag1||rfidStr==tag2||rfidStr==tag3){
digitalWrite(LED,HIGH);
servo.write(75);
worktime = millis();
if(millis()-worktime>10000)
{
digitalWrite(LED,LOW);
delay(100);
digitalWrite(LED,HIGH);
delay(100);
digitalWrite(LED,LOW);
delay(100);
digitalWrite(LED,HIGH);
delay(100);
digitalWrite(LED,LOW);
servo.write(-75);
}
}else {
digitalWrite(LED,LOW);
}
}
oldtime=millis();
}
}

我成功了！
#include <SoftwareSerial.h>

boolean workmodel;
boolean readTag(){
boolean ok = 0;
if (RFID.available()){
delay(1000);
for(byte i=0;i<taglen;i++){
temp[i] = RFID.read();
}
RFID.flush();
ok = 1;
}
return ok;
}
void setup(){

{

for (byte i=0;i<taglen;i++){
rfidStr += temp[i];
}
Serial.println(rfidStr);
if(rfidStr==tag1||rfidStr==tag2||rfidStr==tag3){
worktime = millis();
workmodel = 1;
}
}
if(workmodel){
if(millis()-worktime<30000){
digitalWrite(LED,HIGH);
servo.write(75);
}else{
digitalWrite(LED,LOW);
delay(100);
digitalWrite(LED,HIGH);
delay(100);
digitalWrite(LED,LOW);
delay(100);
digitalWrite(LED,HIGH);
delay(100);
digitalWrite(LED,LOW);
servo.write(-75);
workmodel = 0;
}
}
oldtime=millis();
}
}
太感谢楼上的好心人了，听君一席话不敢说胜读十年书七八年的分量还是有的

兄弟，rfid.flush();这个函数是什么意思啊
