[Arduino] MANY CHANGES!
          * Able to get the speed from the phone. (parsing is better but still a problem)
          * Turn is working from the phone and stop automatically (~75% times) but there is a bug sometime.
          	=> Automatically stop the turn action on forward/backward action to avoid infinite turn. (Some trouble with the socket or else :/)
          * Add a "stopTurn" action to just stop to turn. (don't change the frontWheels)
          * Default honk duration is now 250 instead of 1000 due to change of event listener on the app. (Sounds really better, almost real-time!)
          * Don't stop the wheels before go forward/backward. Managed by the app.
          * BUG: Unable to use the speed for set the rearWheels. I don't understand why but it could be because the value is wrong and this motor reacts differently than the front motor.
