Facial recognition and Arduino? Yes - it is possible, however with the aid of a Windows-based computer and a webcam. The process has been explained by Instructables user "shadowinfinity" with an interesting solution to the problem. They use a PC and webcam and Key Lemon facial recognition software that takes care of human-machine interface. When a face has been recognised the software sends a character to the Arduino via USB which commands it to take action - in this example switching a door strike.
If you found the project above interesting - but not sure how to start with Arduino - then the best way to learn is with our Experimenter's Kit for Arduino:
The package includes a wide variety of parts, sensors and modules including: a servo motor, lights, buttons, switches, sound, sensors, breadboard, wires and more. Furthermore a Freetronics Eleven Arduino-compatible board is included to make this an extensive hobby experimenter, inventor and starter kit. However we don't leave you alone to figure it all out, included is a great project and instruction booklet, plus access to a supporting web page and software examples. In other words - this is everything you need to get started for a fun range of electronics and Arduino related projects!
