+/* Sweep
+
+   Rotazione di un servomotore tramite la librerio Servo.h .
+
+L'utilizzo della libreria Servo rende inutilizzabile analogWrite()
+sui pin 9 e 10 dato che utilizza i timer associati a questi PIN.
+
+Power: un servo da 9g puo' arrivare ad impegnare 750mA sotto carico
+(se viene opposta resistenza al movimento del servo), un  SG90 prende 
+~52mA se il movimento e' libero. Quindi in fase di test il servo puo'
+essere alimentato direttamente da una scheda Arduino (200ma dal PIN 5v)
+ma per l'uso finale dovra' essere alimentato autonomamente.
