RFIDuino Getting Started Guide

This guide will teach you how to connect and use the RobotGeek RFIDuino Shield.

This guide will refer to the RobotGeek Geekduino, the Arduino Compatible microcontroller recommended for use with RobotGeek products. However this kit will also work with the Arduino Uno, or other Arduino variants like the Seeeduino.

What is RFID?

RFID stands for Radio Frequency IDentification. The RFID system consists of two components, an RFID reader and an RFID tag. The reader interacts wirelessly with a tag to retrieve an identification number. The system can be used for many things from opening doors, to tracking inventory.

What is the RFIDuino?

The RFIDuino Shield for Arduino adds RFID capabilities to your Arduino. The shield fits onto your Arduino and removes the need for external breadboards and circuits. The built in buzzer and LEDs allow you to get stared right away. The shield also allows you to add components to expand your system. You can use this to make your own door locks, inventory systems. The RFIDuino system comes with :

  • RFIDuino Shield
  • RFIDuino Antenna
  • 20cm Connection Cable


  • XBee Socket for wireless communication
  • RFID Antenna is separate from the main board
  • Easy access 3-pin Signal-Vcc-Ground breakout for analog and digital pins
  • Onboard Buzzer and LEDs

Onboard Outputs

  • 1 x Piezo Buzzer - Digital Pin 5
  • 1 x Red LED - Digital Pin 3
  • 1 x Green LED - Digital Pin 2

External Connectors

  • 1 x XBee socket - Digital Pins 0/1 RX/TX
  • 4 x 3-pin RobotGeek Digital I/O Ports - Digital Pins 9, 10, 11, 12
  • 4 x 3-pin RobotGeek Analog Output Ports - Analog Pins 0,1,2,3
  • 1 x 4-pin I2C port - Analog Pins 4/5
  • 1 x 4-pin antenna port

Onboard Circuity

Range and Tag Information

  • The average read range of our reader is 70-100mm. This may vary depending on how much power your giving the system and the type of tag you are using. Learn more here
  • Our tags are read only. Each tag comes with a predetermined unique 40-bit (5-byte) ID number.
  • Our tags and reader use the EM4102 Standard.

Setting up the Arduino Software

Geekduino Getting Started Guide

If you have not already set up your Geekduino/ Arduino compatible board, please see the Geekduino Getting Started Guide. This guide will assist you in getting set up with the Arduino software as well as install libraries and test sketches for the Desktop RoboTurret.
