The Materials

Wifly RN-XV

The RN-XV module by Roving Networks is a certified Wi-Fi solution especially designed for customer who want to migrate their existing 802.15.4 architecture to a standard TCP/IP based platform without having to redesign their existing hardware. In other words, if your project is set up for XBee and you want to move it to a standard WiFi network, you can drop this in the same socket without any other new hardware.

Finger Print Scanner - TTL (GT-511C3)

The module itself does all of the heavy lifting behind reading and identifying the fingerprints with an on-board optical sensor and 32-bit CPU. All you need to do is send it simple commands. To get started, just register each fingerprint that you want to store by sending the corresponding command and pressing your finger against the reader three times. The fingerprint scanner can store different fingerprints and the database of prints can even be downloaded from the unit and distributed to other modules. As well as the fingerprint “template,” the analyzed version of the print, you can also retrieve the image of a fingerprint and even pull raw images from the optical sensor!

Arduino Uno - R3

This is the new Arduino Uno R3. In addition to all the features of the previous board, the Uno now uses an ATmega16U2 instead of the 8U2 found on the Uno (or the FTDI found on previous generations). This allows for faster transfer rates and more memory. No drivers needed for Linux or Mac (inf file for Windows is needed and included in the Arduino IDE), and the ability to have the Uno show up as a keyboard, mouse, joystick, etc.

Arduino Yun (Alternative for Arduino Uno + Wifly RN-XV)

Using Arduino Yun is an alternative in using Arduino Uno + Wifly RN-XV since the Arduino Yun already has a built-in Wi-fi in it. Arduino Yun is the first member of a new groundbreaking line of WiFi products combining the power Linux with ease of use of Arduino. The first Arduino Yun is the combination of a classic Arduino Leonardo (based on the Atmega32U4 processor) with a WiFi system-ona-chip running Linino (a MIPS GNU/Linux based on OpenWRT). Arduino embedded the Linux machine directly on the PCB of the Arduino Leonardo and connected the two so that from Arduino it’s very easy to run commands on the Linux side and use it as an Ethernet and WiFi interface.
