4. What is Arduino®
Arduino®is an open-source prototyping platform based in easy-to-use hardware and software. Arduino®boards
are able to read inputs –light-on sensor, a finger on a button or a Twitter message –and turn it into an output
–activating of a motor, turning on an LED, publishing something online. You can tell your board what to do by
sending a set of instructions to the microcontroller on the board. To do so, you use the Arduino programming
language (based on Wiring) and the Arduino®software IDE (based on Processing).
Surf to www.arduino.cc and www.arduino.org for more information.
5. Overview
VMA100
The VMA100 (Arduino®Uno compatible) is a microcontroller board based on the ATmega328. It has 14 digital
input/output pins (of which 6 can be used as PWM outputs), 6 analogue inputs, a 16 MHz ceramic resonator,
a USB connection, a power jack, an ICSP header and a reset button. It contains everything needed to

VMA102
The VMA102 (Arduino®compatible Nano 3.0) is a small, complete, and breadboard-friendly board based on
the ATmega328 (Arduino Nano 3.x) orATmega168 (Arduino®Nano 2.x). It has more or less the same
functionality of the Arduino®Duemilanove, but in a different package. It lacks only a DC power jack, and
works with a mini-B USB cable instead of a standard one.
