AN INTRODUCTION TO THE ARDUINO
WHAT THE ___ IS AN ARDUINO?
• An Arduino is a simple, inexpensive, open source platform for the prototyping and development of electronically controlled devices.
2005 Ivrea, Italy by Massimo Banzi and David Cuartielles
~500,000 in use 2012
Fork of Wiring/Processing Projects, descended from MIT
