I recently completed an RFID project using an Arduino and the Parallax RFID Serial Card Reader - here are the hardware and software notes on making it all work.

Parts List:

1 - Arduino ( I am using an UNO R3 for this demo)
2 - Parallax RFID Serial Card Reader
3 - Solderless Breadboard

Step 1: Wiring the RFID Reader

Insert the RFID board into the solderless breadboard.

Jumper 5V to VCC on the RFID Board
Jumper GND to GND on the RFID Board
Jumper Digital IO pin 2 on the Arduino to /Enable on the RFID Board
Jumper Digital IO pin 5 on the Ardunio to SOUT on the RFID Board

If you power up the Arduino the LED on the RFID Reader should light green. In the next steps we will load the library and code to make the reader work.
<p>Hello I need to use parallax RFID Reader Serial with WiFi<br>module esp8266 and LCD using pic16f877a. every time I run the circuit the RFID<br>doesn&rsquo;t work</p>
<p>hola.</p><p>espero y me puedas ayudar </p><p>tengo una tarjeta RFID read/write pero no he podido leer unas tags que compre y solo tengo una que es la que traia pero aun asi no se que hacer </p><p>como le haria para que me funcione</p>
