 /* Simple Motor
- This sketch use a transistor and a diode
- in order to power a 5v ~150mAh directly from the board.
- Hard thing is to find a suitable motor!
 
- In order to power a more powerfull motor you need to connect
- the transistor to an other power line. 
+Gestione di un motore DC tramite Arduino.
+Elementi richiesti:
+
+- motore DC a 5v per ~300ma
+- transistor NPN 2N2222
+- diodo 1N4001
+ 
+ Schemi:
+ - Breadboard: http://lab.piffa.net/schemi/motor_transistor_diode_bb.png
+ - Schema circuito: http://lab.piffa.net/schemi/motor_transistor_diode_schem.png
