Имеется Arduino UNO

стандартный скетч WebServer полностью устраивает только необходимо добавить туда чтобы в вебпанели выводилась информация с rfid(RC522) считывателя, а именно Card UID(номер карты), подскажите пожалуйста как это можно сделать? Спасибо!

002  Web Server
003 
004 A simple web server that shows the value of the analog input pins.
005 using an Arduino Wiznet Ethernet shield.
006 
007 Circuit:
008 * Ethernet shield attached to pins 10, 11, 12, 13
009 * Analog inputs attached to pins A0 through A5 (optional)

02 * ----------------------------------------------------------------------------
03 * This is a MFRC522 library example; see <a href="https://github.com/miguelbalboa/rfid" title="https://github.com/miguelbalboa/rfid" rel="nofollow">https://github.com/miguelbalboa/rfid</a>
04 * for further details and other examples.
05 * 
06 * NOTE: The library file MFRC522.h has a lot of useful info. Please read it.
07 * 
08 * Released into the public domain.
09 * ----------------------------------------------------------------------------
10 * Example sketch/program showing how to read data from a PICC (that is: a RFID
11 * Tag or Card) using a MFRC522 based RFID Reader on the Arduino SPI interface.
12 * 
13 * When the Arduino and the MFRC522 module are connected (see the pin layout
14 * below), load this sketch into Arduino IDE then verify/compile and upload it.
15 * To see the output: use Tools, Serial Monitor of the IDE (hit Ctrl+Shft+M).
16 * When you present a PICC (that is: a RFID Tag or Card) at reading distance
17 * of the MFRC522 Reader/PCD, the serial output will show the ID/UID, type and
18 * any data blocks it can read. Note: you may see "Timeout in communication"
19 * messages when removing the PICC from reading distance too early.
20 * 
21 * If your reader supports it, this sketch/program will read all the PICCs
22 * presented (that is: multiple tag reading). So if you stack two or more
23 * PICCs on top of each other and present them to the reader, it will first
24 * output all details of the first and then the next PICC. Note that this
25 * may take some time as all data blocks are dumped, so keep the PICCs at
26 * reading distance until complete.
27 * 
28 * Typical pin layout used:

Не вижу, чтобы вы пытались обьединить два скетча. Почитайте правила форума, никто за вас это делать не будет, здесь помогают тем, кто пытается решать проблемы сам.

И еще - имхо, сама идея выводить UID карты в Вебпанель - не слишком удачная
