RFIDuino Project 3 - Wireless Communication with XBees

Description

This Project will use the same code as RFIDuino_helloworld3. This time however, we will be sending the data over the computer wirelessly using 2 XBees and a UartSBee.

Hardware Required

Instructions

  1. Load the RFIDuino_helloworld3 sketch onto your arduino. You can find this sketch under
    File>Examples>RFIDuino>RFIDuino_helloworld3
    NOTE:You cannot program the Arduino if the XBee is connected. Remove the Xbee or shield when you are programming your Arduino.
  2. Connect your components as shown here. RFIDuino-xbee2_bb1000.png
  3. Connect the UartSBee to your computer via USB. This device will show up as a serial port in the Arduino IDE. Pick that serial port and open a serial terminal.
  4. Attach your RFIDuino to an external power supply like a battery or power brick.
  5. Swipe the 'key' tag across the Rfiduino antenna. The green light will light up and your buzzer will sound. The RFIDuino will also transmit the ID to your computer via the XBee.
  6. Check your serial terminal on your computer. You should will see the tag IDs just as if you had your RFIDuino plugged into your computer.

Explanation

Normally the Arduino uses pins 0(RX) and 1(TX) to communicate with the computer. With our new hardware setup, the XBee will take those pins and use them to transmit wirelessly. The second xbee will pick up that communication and relay it to the computer via the Xbee.
