 /* 
- Simple Motor with variable spped from pot input
+  Simple Motor : Potenziometro con minimo
+  
+ Motore DC con variazione della velocita' impostata 
+ tramite un potenziometro 10k ohms,
+ settato un valore minimo sotto il quale il motore
+ non viene attivato.
+ 
+ Schema: http://lab.piffa.net/schemi/motor_pot_bb.png
  
- This sketch use a transistor and a diode
- in order to poer a 5v ~150mAh directly from the board.
- Hard thing is to find a suitable motor!
-
-
-  This version uses a pot as throttle control,
- serial for debuggin.
-
- Optimized for a minimum throttle value in order to keep the motor off
