新手求幫助。RFID門禁問題
http://img04.taobaocdn.com/imgextra/i4/178252798/T2taj4XttaXXXXXXXX-178252798.jpg我是這個模塊，現在的問題是還沒解決屋內解鎖問題
我已有按鈕，但不會編寫下一步，求幫助
以下是我的arduino code
#include <EEPROM.h>
#define EEPROM_write(address, p) {int i = 0; byte *pp = (byte*)&(p);for(; i < sizeof(p); i++) EEPROM.write(address+i, pp);}
#define EEPROM_read(address, p){int i = 0; byte *pp = (byte*)&(p);for(; i < sizeof(p); i++) pp=EEPROM.read(address+i);}
char val; // variable to receive data from the serial port
const int ENPin = 2; // 定義使能管腳
int ENState = 1;//初始化使能狀態為高電平
// lock 1
int PWMA = 2;
int LED = 3;
unsigned long ID = 0; unsigned long IDR = 0;
unsigned long ID1 = 0; unsigned long IDR1 = 0;
unsigned long ID2 = 0; unsigned long IDR2 = 0;
unsigned long ID3 = 0; unsigned long IDR3 = 0;
unsigned long ID4 = 0; unsigned long IDR4 = 0;
unsigned long ID5 = 4241884143; unsigned long IDR5 = 0;
void setup()

}
void loop()
{
for(ENState = digitalRead(ENPin) ; ENState == LOW && Serial.available() > 0; ) //判斷使能端是否為低電平，是且串口有輸入，則讀入卡號
{
ID = ID * 10 + int(Serial.read()-'0'); //讀出卡號
delay(2); //加個小延時，讓串口有充裕的時間讀出資料
}
if(ID != 0) //如果ID記憶體的值不為0，則輸出該卡號
{
Serial.println(ID);
if(ID == IDR) Serial.println("welcome! TimYiu"); //判断是否与EEPROM中的卡号相匹配
if(IDR==ID)
{
digitalWrite(LED, HIGH); // set the LED on

}
}
void leftForw(){

{

digitalWrite(PWMA, HIGH); // set the LED on

求指教。。。。
